It has been quite some time since my last post, and I apologize to anyone off put by the delay! (I think I may be flattering myself with that one...). As business has continued to grow, expand, and time has not begun multiplying itself I fell behind on this blog. However, the months that have passed since my last post have been filled with meeting great organizations and people. The conversations and discussions we have had lead me to hone in some exciting ideas and opportunities to create value in an industry that does a tremendous amount for our communities: Nonprofits!
While I enjoy working with organizations across many industries, markets, and specialties I find that I can be a part of truly impactful conversations when I am meeting with a nonprofit organization. My opinion as to why this is that there is an inherent emotional passion and mission behind the organization's operation. There is a passion there that drives these people to make a difference in the community they are in, the cause they are representing, or the change they are trying to make. I love connecting with this passion, and I love the opportunity to help strengthen their ability to chase that passion. I will share with you today why I am passionate about this industry and how I feel we can change the conversation of how mechanical systems play into operation.
I was in the middle of meeting with a potential client, a nonprofit, recently and we were talking about their current situation. As I find many times their current situation was this: currently had a maintenance contract for the HVAC systems, there was a void in communication when it came to what that contract meant, and there was a feeling of not getting what they needed, and they were paying a lot of money.....and I mean a lot of money. They were looking to see what else was out there, and wanted to know what we could do for them in comparison. They began to ask me about scope of work, how many times per year we would come out for inspection, how many times we would change filters....the standard questions. That's when it hit me-no wonder they are not getting what they want, we are not having the right conversation. The conversation they are used to having in this situation is one of technical specs and maintenance tasks to be performed. Simply put, this is not effective, and it is short-sighted in many ways.
There is not enough information in this conversation to make the most appropriate and impactful decision for the organization. The decision relies solely on what someone tells you "needs to happen"....yea that's not how I make decisions either. The conversation needs to be one of direction, planning, and goals. How can an organization be sure the program they decide is right for them if they have not taken the time to look at how it relates to their mission, their operation, and their long-term goals. Without having this discussion, you are stuck in an expensive sports car when you need a cost efficient SUV....or vice versa!
This conversation and approach is important in every business, but as I mentioned above, there is such an important opportunity within nonprofits. The economy has dried up some funding options, while making others more competitive. Donors' dollars are being pulled in many more directions, government funding is not what it used to be and we are not sure what that will look like down the road. I don't need to tell nonprofit organizations what their challenges are when it comes to raising money and maintaining a sustainable operation-they are in it every day. However, I do have plenty I can tell them about making every dollar on the back-end count, managing the overhead expenses related to the mechanical equipment, and make sure as much revenue as possible is reinvested into the organization to further its mission and service to the community.
In conclusion, nonprofits need to change the conversation they are having about their HVAC maintenance, and all vendors for that matter. They need to look at it on a macro-level and really understand how this impacts their operation on every single level-operationally AND financially. I hope to have this conversation with as many organizations that are doing good in our community and to help them make the best decisions for their specific situation.
I will be diving further into nonprofit challenges as I see them in future postings....and I promise it won't take me four months for the next post!

Man It's Humid in Here!
In my post titled Challenges in Preserving History I discussed the importance of maintaining a specific climate in these spaces, and the benefits of doing so. My focus in that post was more from an operation and financial standpoint, from which I would like to elaborate today in the direction of climate affect and what the climate should be. The information that I will outlay in this post is from the National Park Service Museum Handbook Part 1 (1999), and I will be covering only the "agents of deterioration" that are potential factors resultant to improper air quality and condition. I will get into these agents shortly.
This post is my longest to date, and I have put off publishing it for the past couple of weeks. I couldn't seem to find my voice and get across the information that I wanted to. I enjoy injecting my thoughts, viewpoints, passions, and recommendations into the posts I write. This post is more information and research rich, with less of the personalization that I like. However, this is vital information that I feel compelled to convey in the most straight-forward, fact-filled way.
I have had the opportunity since my last post to work with a number of historical sites, and I am continuing to learn about the absolute importance of maintaining the appropriate climate and environment so that preservation can be successful. History connects us on such a personal level to those who came before us. It gives us insight to why we are where we are today as an individual, a family, a country, and a people. Not to mention, these structures are built with an artistic attention to detail and a charismatic aura that simply does not find its way into our structures today. Do not get me wrong, the buildings that are being built today are the work of engineering genius and they are impressive in so many ways. However, In my opinion, they lack the character that I see in so many historical sites around cities like Richmond, Charleston (SC), Savannah...just to name a few. I want these places and artifacts to be around for generations to come so they too understand the journey that was taken.
The ominously labeled agents that I touched on above (agents of deterioration) are the factors that act negatively upon an object from the time it is created. the NPS says there are four agents related to the category "environment", which are as follows: temperature, relative humidity, light, and air pollution. I will touch on all with the exception of light, as I would be speaking without being educated on this---and I do not make a practice of speaking unintelligent. My goal is to help institutions understand what each one of these agents is, what contributes to the agents' license to kill (yea I went there), and how to eliminate the threat or at least reduce the effects.
Let's begin by laying the foundation of this discussion by going over the types of objects or materials that are housed within these buildings or sites and are vulnerable to these agents. Broadly speaking, there are three categories of materials that make up these historical gems: Organic, Inorganic, and Composite.
Organic objects are derived from plants or animals, and show themselves in wood, paper, textiles, leather, skins, horn, bone, and ivory, grasses, bark, lacquers, plastics, some pigments, shell, and biological natural history specimens. The NPS states these organic items share characteristics such as: containing an element carbon, are combustible, absorb water from and emit water to the surrounding air, are sensitive to light, and are a source of food for mold, insects, and vermin (gross!). These items are vulnerable to deterioration from extreme changes in temperature and humidity.
Inorganic objects still have a geological origins, and come in the form of metals, ceramics, glass, stone, minerals, and some pigments. These items have undergone extreme heat or pressure in their creation, are not combustible at normal temperatures, can react to their physical environment to change their chemical structure (ex. corrosion), may be porous, and are typically not sensitive to light.
Composite objects, are made up of two or more materials. For example, a book is composed of several materials such as paper, ink, leather, thread, and glue. Depending on the materials, these objects may have characteristics of both organic and inorganic objects while the individual materials react to the environment in different ways.
The actual deterioration of these objects and materials is the change in either the chemical makeup or the physical structure. This deterioration rears it's ugly face of destruction in the form of rusting, corrosion, fading, darkening, rotting, cracking, warping, shattering, structural failure, to name a few.
We touched on what the materials are and what can happen to them, now let's get into what these agents are: Temperature and Humidity. If you're like I was prior to having an understanding of HVAC (albeit still a limited understanding at present) you know when you're hot you turn the thermostat down and when you're cold, you turn it up. That was literally my understanding prior to getting into this business. There is a bit more to it than that so I have found out.....
Temperature and Humidity, these two forces work together to create a climate inside the conditioned space. We feel fluctuations physically in both, and so do the aforementioned objects. It is important to understand what the adverse affect of these fluctuations can be so that preventative action can be take to preserve most effectively.
Temperature is defined as a measure of motion of molecules in a material. When the temperature increases, the molecules move faster and spread out causing the material to expand. When temperature decreases, molecules....you got it....they slow down and the material contracts. At higher temperatures, chemical reactions and biological activity increase-neither of which is a good thing. These chemical reactions can cause extreme deterioration that can go unnoticed for quite a long time, at which point it may be too late to save the object. Biological activity sounds even less fun-creepy crawly critters chewing (say that 5 times fast). Insects eat more and breed faster in warmer temperatures.....*shivers*. Additionally, materials can soften at these higher temperatures. At lower temperatures paints, adhesives, and other polymers can fracture.
A good temperature range to shoot for is, on average, is somewhere between 64 and 68 degrees. Just as important as the actual temperature is maintaining a consistent temperature. Fluctuating temperatures can cause materials to expand and contract rapidly, setting up destructive stresses in the object. Temperature in turn has a hand in determining relative humidity-when temperature varies, relative humidity varies.
Relative humidity is defined as the relationship between the volume of air and the amount of water vapor it holds at a given temperature. Water plays a large role in various chemical and physical deterioration, making relative humidity an important factor in preservation efforts. Excess humidity in these facilities can come from many sources and show themselves in many forms. Exterior humidity levels, rain, bodies of water, wet ground, broken gutters, leaking pipes, moisture in walls, human respiration and perspiration, wet mopping, flooding, and cycles of condensation and evaporation.
As a benchmark for relative humidity, 50% RH means that the air being measured has 50% of the total amount of water vapor it could hold at a specific temperature. It is important for me to note and for you to understand that the temperature of the air determines how much moisture the air can hold. Warmer air can hold more water vapor, because an increase in the temperature causes the air molecules to spread out-creating more space for more water. Relative humidity is directly related to is also inversely related to temperature. In a closed system, when temperature goes up-RH goes down. When temperature goes down-RH goes up.
Since the materials that are housed in or make up these facilities have already endured the elements for many many years, they need just the right environment to survive. Relative humidity that does not fall within the needed range can cause deterioration in numerous ways. When RH is too high chemical reactions increase, just as they do when temperature rises. Metal corrodes, dyes fade, wood swells and warps, adhesives become softer, paper may buckle, canvas paper can slack, and biological activity is supported by higher RH levels. Low RH levels can cause shrinkage, warping and cracking of wood, leather can crack and flake as can photographic. Finally, an environment where RH significantly varies has a large effect on organic materials. Swelling and contracting by constantly adjusting to the environment creates deterioration. These deterioration may come suddenly or may happen over time, and potentially go undetected until a final layer gives way or structural damage occurs. Materials that are at the high risk to fluctuations are laminate and composite materials such as photographs, veneered furniture, and paintings.
The RH range needed for a specific collection is based on what the collection includes. I have included ranges for a number of different materials and objects below. Again, this is an average and actual ranges are on a case by case basis.
Archaeological Materials
Negligible Climate-Sensitive Materials:.................................................................................30%-65%
Climate Sensitive-Materials:..................................................................................................30%-55%
Significantly Climate Sensitive Materials:.............................................................................30%-40%
Metals:....................................................................................................................................<35%
Natural History Materials
Biological Specimens:.............................................................................................................40%-60%
Bone and Teeth:.......................................................................................................................45%-60%
Paleontological Specimens:.....................................................................................................45%-55%
Pyrite Specimens:....................................................................................................................<30%
Paintings:...............................................................................................................................40%-60%
Paper:.....................................................................................................................................45%-55%
Photographs/Film/Negatives:...............................................................................................30%-40%
Other Organics (wood, leather, textiles, ivory):.................................................................45%-60%
Metals:....................................................................................................................................<35%
Ceramics/Glass/Stone:..........................................................................................................40%-60%
Many collections include a vast array of the above materials and objects. With that being said, a good RH to shoot for in a museum setting would be around 45% relative humidity.
We've all heard the phrase: "A picture is worth a thousand words". To conclude this post, I am going to use some visual examples of deterioration to hopefully allow all of these facts and figures to come full circle and make sense. Two thousand words from me to you....
This was a lot of information, and I hope that I laid it out in a way that was easy to follow and comprehend. I have found a passion in preserving history, one that I wasn't aware of until I was immersed in it. The beauty and the story of history is one that I cannot describe with words on a blog. It is something that has to be experienced, has to be taken in, has to be absorbed into the mind, body and soul. With knowledge, we can ensure that these buildings and collections are around for generations to come and give them the gift of history.

Pay It Forward, So We Can #HelpTuckerBreathe
I would like to use this platform today to discuss something far more important than bottom-lines and profits, more impactful than operational efficiency, and immensely larger than any one of us.
Many of you reading this, and myself included, spend an overwhelming majority of our time throughout the day focusing on things such as our careers, bills, and countless other "worries" that we do not take time to appreciate how precious our lives actually are. We get caught up in things that hold such a small significance to who we really are and what adds value to our lives. We are rarely faced with a "life or death" situation, regardless of how pressing something may seem we can almost always recover from it. We can get ourselves out of debt, we can re-establish ourselves after a lost job or failed relationship, we can get back into shape after an injury....the point being, these obstacles, however tough, can be overcome.
Imagine for a moment being 25 years old and facing a disease like Cystic Fibrosis, an incurable monster that attacks your lungs leaving them useless. Imagine being in the ICU for weeks at a time, fighting every single second of every day. Think about having to make the decision to apply for a double lung transplant so that you can continue to be there for your family and friends and experience life. THIS is a real life or death situation. And THIS is real life for my best friend Tucker. The most amazing thing about this is that Tucker is positive, strong, and the only person I know that can get through this.
In the time I have known Tucker he has been a constant in my life. We understand each other is some weird-unspoken way, and I have benefited more than I can express from having the privilege of knowing him. No matter how hard things are, no matter how many times he has gone to the hospital for his "tune ups", no matter what life throws at Tucker-he handles it, and he handles it with a calming positivity that is so inspiring. He has taught me, whether he knows it or not, how to be strong in the face of adversity. How can I complain about my "problems" if he steps up and pushes through everything like he does.
Another thing about Tucker that always amazes me is that he KNOWS EVERYONE! I've been out with Tucker in the Fan, in the Bottom, at Innsbrook After Hours, and everywhere else is Richmond and people are coming up from every direction saying "TUCKER!!" "What's up!?" or Tucker will tell me to hold on so he can say hi to someone, it is crazy! However, I know exactly why that is: Tucker is genuine. He is himself all of the time, and puts on a front for no one. He is a great person and an even better friend. We can all learn a thing or two about being genuine from Tucker, I know I have.
For everything Tucker has done for me and my life, I feel honored to have the ability to do any small token I can to help him. He is facing an incredibly tough time ahead and he needs to the support of his friends, his family, and strangers alike. There will be many challenges in the road for Tucker and his family, and we can all do a little bit to make that easier. I am hope you will take a few moments to look at the following links and see just how special he is and the support that he already has at his back. Once you have done that, I encourage you to act in some way. Whether it be sharing the Facebook group, posting a picture of yourself with the #HelpTuckerBreathe on Twitter or Facebook, donating to the fund that is being collected to help him be accepted by Duke for the Double Lung Transplant, or simply keeping Tucker and his family in your thoughts.

My Humble Offering to Hotel Logistics
I was stopping in to speak with a potential client last week, a beautiful hotel here in Richmond, and spent some time chatting with a gentleman at the front desk. We both happened to be on the same page about numerous issues: love of the city (him-Fan, me-Church Hill), Richmond's great restaurants, and the disdain for people who do not follow simple rules. The latter topic came about while we were on the issue of parking, or lack thereof, in the Fan. I told him a situation I encountered that previous weekend of a less-than-conscientious driver in my beautiful neighborhood while I was on a morning walk with the dog. As Morgan and I are walking Colt down Broad street, we pass Captain Buzzy's (highly recommended for coffee lovers) just as someone pulls into an empty spot along the curb right in front of the shop. For starters, this is a no-parking zone and there was a perfectly legal spot directly across the street. Secondly, he was facing the wrong direction(!!!!).... I am not one that understands or grasps the mindset of being above the law or common rules of humanity, so this situation slightly infuriated me...and on such a beautiful day! In case you are wondering, no he was not the President, Pope, or God (I would have loved to back a tow truck up to his car and move to the other side of the street, but I do not have such resources). This rolled back in the folks who feel that rules simply do not apply to them. I inquired if that came into play while doing his job, and while he was more than professional and politically correct by deflecting a question that would put his guests in poor lighting, it got me thinking about the logistics of a hotel....and how I probably could not deal with that if it were my job.
Just think for a minute about what has to go into a full scale, happening hotel on a day to day basis. The amount of people checking in and out, the rooms that need to be cleaned, the food served, the amount of drinks consumed at the bar, shuttles taking people to and fro (not sure if that is still an acceptable phrase these days). Every hotel has check in and check out times, but who really wants to wait until 3pm right?! I guarantee if you managed a hotel, or had the privilege of fielding the questions such as "Why do I make a reservation if my room isn't even ready!?" (5 hours before check in time) you would never ask that question at a hotel again. My point being-hotels HAVE to be an efficient, well oiled machine to keep their guests satisfied and coming back. (And the hotel I am speaking of does that amazingly).
This thought process, once I had some coffee, started to swirl and lead me to think what I could do to assist a hotel in achieving operational perfection. I cannot, nor do I want to, handle those questions from customers. But I can directly impact a customer's stay at the hotel, as well as assist the hotel staff and management in streamlining hotel processes. What we do, in the maintenance contract world, is create a plan to achieve a goal. I am expending much energy getting the topic of mechanical equipment and operation into the discussion of "a means to achieve a goal" so to speak. There is endless amounts of money poured into poorly operating HVAC equipment. Money that could find its way down to the bottom line as PROFIT instead of being paid to energy utilities, repair work, parts, etc. In addition to the back end of this, I can also affect the front end-comfort conditions. If I help develop a plan that has the equipment operating effectively and efficiently then guests will reap the benefits of simply being comfortable, and that goes an incredibly long way.
This entry was more about my personal observations and opinions as opposed to hard data, but I look at this topic as my responsibility and my "masterpiece". The recommendations I propose to potential clients are carefully thought out and crafted with a focus on detail that makes the finished proposal essentially my work of art. If I can affect, positively, an operation with my recommendations and plans then I have succeeded and that gives more satisfaction than anything else.

Just think for a minute about what has to go into a full scale, happening hotel on a day to day basis. The amount of people checking in and out, the rooms that need to be cleaned, the food served, the amount of drinks consumed at the bar, shuttles taking people to and fro (not sure if that is still an acceptable phrase these days). Every hotel has check in and check out times, but who really wants to wait until 3pm right?! I guarantee if you managed a hotel, or had the privilege of fielding the questions such as "Why do I make a reservation if my room isn't even ready!?" (5 hours before check in time) you would never ask that question at a hotel again. My point being-hotels HAVE to be an efficient, well oiled machine to keep their guests satisfied and coming back. (And the hotel I am speaking of does that amazingly).

Begin With the End in Mind
One of the main ideologies or themes that is ever-present when I am working with clients is planning. Planning is the foundation of progress and achieving operational and financial goals. Merriam Webster defines a plan as a "method for achieving an end." For a plan to be effective, it must include looking into the future, or the end, and preparing for what may be encountered or decisions that will need to be made. If you are making a plan to take the vacation of a lifetime, you need to know what that looks like so that you can save money, book lodging, travel, or getting a lay of the land. If your plan is to get in shape, you need to have a visual of what that is so that you select a workout and diet regimen that will allow you to achieve the goal. Without visualizing or understanding you want the future to look like, you will not be doing the things needed today to step off of the plane for that vacation or to see yourself transformed.
In the realm of HVAC systems, the "future" is the visual of a crane replacing a rooftop unit. Meaning, the things we do are to extend the equipment replacement date as far into the future as we can AND prepare for the day that it does. Both of these are exceptionally vital to the long-term planning of any organization with responsibility of their facility's HVAC equipment. This equipment, like any piece of mechanical equipment, does not last forever-and it should not be pushed past it's useful life. Let's look at a loosely-similar analogy, of an old car that has been have recurring issues of shutting off randomly. You may have some sentimental emotions of the car, so you get it repaired once, maybe twice, but it is continuing to happen. Luckily it has not happened to shut off while driving down the interstate...yet. By this point, many of us will look at replacing that car with a new one before we hurt ourselves, someone else, or our wallets. An HVAC unit that is in operation past its useful life, can result in some of the same consequences. Poor indoor air qualify (IAQ), decreased comfort conditions, and increasing repair costs are all potential issues caused by an old unit.
The American Society of Heating, Refrigeration, and Air Conditioning Engineers have conducted a great deal of research that has produced helpful data on the service life of HVAC equipment. I have supplied this information here for you to give you an idea of how long, on average, this equipment is expected to last. Does this mean you must replace every unit you have that is over the listed age? Absolutely not, this should be used as a point of reference and education. I have seen quite a few units around town that have far surpassed this life expectancy. However, going too far past a unit's life expectancy can result in a reactive decision once that unit goes down, not to mention dealing with poorly operating equipment. This information should be used to plan budgets, determine future capital expenditures, and to develop a plan so that you are not caught in a reactive state.
There are some things that can be done to extend the life of the equipment, and I will give you a hint to what that is: It's everything that I write about on this blog! My entire job is developed around extended the life of the equipment and to help it operate more efficiently in the process.
Now, as promised, here is a chart giving you the Life Expectancy of the equipment that you may have at your facility.

Why "Let's Go With the Lowest Price" Doesn't Always Translate to the Least Expensive Program
We see it everywhere: "Lowest Price in Town!", "50% OFF!","HUGE SALE!!", "We Are the Low Price Vendor!"
The low-cost selection is so pervasive in our culture today that it seems price is the number one factor in many peoples' buying decision process. I'll admit, that I have bought a good/service based on lowest price as I am sure everyone who reads this has. While this is perfectly logical when it comes to small purchase of like items, it is not the most effective buying process for many things, especially those that have a significant impact on our lives. Today, I want to look at this issue in the HVAC maintenance contracts arena and the impacts that it has. I truly feel it is in the best interest of the clients that we, as contractors, serve to move away from this sales and marketing angle. I will start off by saying selecting the lowest-cost vendor is absolutely not going to translate to the least expensive maintenance program.
I understand that may seem like a biased statement, based on the fact that I spend a majority of my awake hours selling contracts. However, I see my role and responsibility as more of an educator than a sales person; more of a partner than an transaction agent. As an educator or partner, I want what is best for the party that I am assisting, and that means securing a program that will produce the best results over an extended period of time-not just at the time of signing the contract.
I feel the following phrase has been uttered by someone around us at some point in time: "You get what you pay for." If you have not heard it before, I think it makes sense. How about another phrase to further simplify: "Good Products/Services are not cheap, and Cheap Products/Services are not good" If or when you are in the process of getting quotes on maintenance contracts and one contract is significantly lower than the other, ask why. I have been in numerous conversations where I am the higher-priced vendor, and I have been asked why I am higher than the other contractor. I, in turn, have asked why they are lower. The work needed to correctly service the equipment is the same regardless of who is performing it. So, how can it be done so much cheaper? When deciding based solely on cost, something is typically left suffering. It has been my experience that maintenance is not performed to the needed level, which leads to a whole host of complications (and expensive complications at that). Be sure to compare the scope of work on the contract proposal.
When the maintenance is not performed to the needed level, the aforementioned complications are three-fold: increased repair, decreased comfort conditions, and decreased equipment life. The increased repair calls are due to the lack of proactive maintenance, that could typically catch the issues prior to it becoming a large problem. When a contract is the lowest-priced, the contractor simply cannot afford to perform the amount of maintenance needed. They are in business to make money, plain and simple. Another reason, and perhaps more controversial, is the practice of selling an extremely low-priced maintenance agreement and then "making it up" on repair billing. Again, with reduced maintenance comes reduced performance. Inconsistent heating/cooling, poor Indoor Air Quality, and downtime due to equipment breakdown are potential consequences of the low-cost contract. Finally, HVAC equipment has an absolute finite life just as any other piece of mechanical equipment. With proper maintenance we can extend the life of that equipment, but without it we can severely limit how long we can claim that equipment as an asset. Think about your car, and how much longer it will last if the oil is changed, tires are rotated, etc. We can expect hundreds of thousands of miles with service and maintenance. However, if we slack on these relatively inexpensive tasks the engine could seize up, or we could require very expensive repairs to keep the car of the road.
Instead of buying and selling based on the bottom dollar price, let's focus on the value we can bring. Be sure that your contractor puts together a program that will help your organization reach its physical and financial goals. Ask questions, be sure you understand what you are paying for. The high price doesn't always mean the contractor is trying to "get one over on you" and the low price doesn't always mean the best "value" or the cheapest overall cost. As the last post outlined, put a process in place to measure the effectiveness of the plan and keep it on track. By acquiring this mindset, I can say with absolute certainty that the costs of your HVAC system will be reduced-and not because you selected your contract based on cost.

The HVAC Success Equation: P+P=P
I am an organized guy, for the most part. I look at a majority of tasks that I find myself faced with as a set of processes. Take my workout regimen for example, at the beginning of each week I plan my workouts down to the exercise and route, develop a loose structure for my meals, and update with current information each day. Throughout the course of the week, I am able to measure how I am performing with relation to my goals (that I have written out and try to read every day). If I find myself veering off course I can implement the appropriate actions (or discipline....I like food) to steer the ship back in the right direction. The point with this example being I find the key to reaching a goal is planning and measuring performance.
I take that same approach when working with my customers on developing a program for maintaining their HVAC systems. It is not effective for me to "propose" a program without having an understanding of what they need. I would not reach my personal fitness goals if someone who had never met me emailed me a workout plan for a world strongman contender (they don't perform well in triathlons or marathons). On that same hand, my customers will not benefit from this approach and frankly I would not enjoy my job if I went about it that way (where is the fun in that approach?). I take pride in my approach, because I know that at the end of the day the customer has all of the information necessary to make the best decision for their company.
That leads us to the "equation":
The term equation may not be the most appropriate, as this is a continuous cycle not a set formula. In this post, I will outline how I go about each one and the factors that I feel are important for companies and organizations to address with respect to their HVAC maintenance program. I will harp on this in every single post:
The HVAC system of a business is more than just hot and cold-it is tied to financial performance, production, employee productivity, reputation, tenant satisfaction. Let's work together to maintain it, prepare for the future, and build on the success of Richmond business. -stepping down from soapbox-
The very foundation to the process is PLAN. This is where the roadmap is formally drawn, so that when the rubber meets the road we head in the right direction. In this stage, the following factors are addressed:
Simply put this stage addresses where we are and where we want to be. Through doing this, everyone is on the same page with what needs to be done and the ability to be ahead of the curve is established. Speaking of being ahead of the curve, it is important to stay up to date on laws and regulations surrounding HVAC equipment (i.e: refrigerant restrictions and changeover-this will be a whole blog post in itself at some point).
Once a plan is in place, it is time to PUT INTO PRACTICE. We have the roadmap, and it is time to accelerate forward. This is where the plan that was created is played out, the systems are maintained, serviced, replaced, and the program is constantly analyzed for execution. When I say constantly analyzed or monitored, I do not mean there is someone designated to do nothing except stand and watch the systems. If done correctly, this is a limited-effort task. Resources such as tasking reports from the contractor display the maintenance performed on specific visits, and electronic service tickets detail work done on a service call (the e-mailed tickets allow for more convenient, and "green", filing). Both exceptionally simple tasks that make an extraordinary difference when it comes to staying on course.
If a plan is not created at the start and followed throughout the day to day operations, everything is in a reactive state. From my perspective, reactive operations are not efficient and effective operations and more importantly-are not performing at their financial peak. With the benchmarks we can plan out equipment replacement so that it falls within the budget period we designated, we monitor equipment to ensure it is operating efficiently, and we keep track of energy usage, repair costs, which units are requiring more service calls, which zones are experiencing more issues than others, etc. Yes, the plans I work with organizations to create are centered around maintenance and the mechanical operation of the equipment. However, I focus on how that impacts the business on a macro level.
To this point we have the Plan and we have Put into Practice. This will lead to Progress, the summation of the first two P's. With the first two done correctly, progress is inevitable-it has to lead to this. It is simple, we defined our goals and our operations were guided by those goals-leading us closer to those goals. At this point, typically at the end of the contract year, we will review the past year taking a look at the whole picture. Having resources that can put that review on paper are priceless, allowing for everyone to understand where we are on the roadmap (think YOU ARE HERE). This gives the chance to revise goals if needed, adjust the direction, and continue with a plan that addresses the needs of the organization at that point in time.
I emphatically believe that this process works, and in my mind is quite logical. Logical is the way I prefer to work, and I have seen success in every aspect of my life when implemented-not just HVAC maintenance.

Cooling Season Can Burn up Your Cash
"Yes! It's FINALLY getting warm out!" This was my first thought, as well as the first thing out of my mouth, when I checked the forecast for today. I am completely over cold weather, and I have a feeling I am not alone in that sentiment. I am looking forward to walking the dog in the mornings and not being chilled to the bone, sitting outside in the evenings, and enjoying the beautiful sunsets from Libby Hill. Point being-I am looking forward to the warm weather. While I will take a stab in the dark and say many of you are as well, I will say your buildings, mechanical systems, and bottom lines are probably not sharing that elation. Throughout this post we will take a look at why, and some of the steps that can be taken to make sure the warm weather keeps our spirits, and profits, up.
Commercial HVAC systems come in all shapes, sizes, designs, and applications. However, they share similar features and equipment needed for the heating, cooling, and ventilation demands of the building. It is important to understand they type of equipment that your facility relies on, but it is not necessary for you to know exactly how everything works together-that is why HVAC contractors and technicians exist. I would like to educate you on one specific, and very important, aspect of your system: the coils. The coils are the heat exchangers of the cycle providing the cool or warm conditions felt in the space. On a basic knowledge level, there are condenser coils and evaporator coils. When I began to learn about the workings of HVAC systems, the following schematic helped give me a basic understanding of what these pieces of equipment did.
ASHRAE (American Society of Heating, Refrigeration, and Air-Conditioning Engineers) conducted a study on the financial benefits of cleaning coils. The article that shares the research and findings is called Study Verifies Coil Cleaning Saves Energy. As always, a link to the article is available at the conclusion of the post. The title does not leave any mystery as to what the results of the study are. However, since I realize many people need to see the backup for such a claim, I will give you the hard facts. One of the first paragraphs in the article really hammer home the importance of proper coil maintenance, and sets the stage for the rest of the article.

When I began to learn about the workings of HVAC systems, the following schematic helped give me a basic understanding of what these pieces of equipment did.
As the drawing indicates (it is a very basic visual of the cycle that only displays the function of each coil, not all parts of the cycle) the evaporator coil inside supplies the space with coil air while the condenser coil outside rejects the heat from the system. Think of your home A/C system. Many people have a condensing unit or two outside of the house somewhere. When you hear that fan come on, the condenser is rejecting the heat, and condensing the refrigerant vapor to a cooled liquid state before sending it back through the system. While commercial equipment is much more complex, the basic theory of operation still remains the same.
Now that we got the technical jargon out of the way, let's start to make "cents" of all of this (sorry, I had to). You can imagine that equipment this focal in the heating and cooling process get its fair share of wear and tear. Being outside, the condensing coils are subjected to weather, dirt, debris, among other elements. This can produce a build up that inhibits the ability of the coil to transfer heat, making the system work harder to meet demand. Think about going out for a long run in August, the heat and humidity at a peak. Your body works harder than normal to maintain your core temperature, rejecting "heat" from your skin in the form of sweat. Now picture going out for that same run while wearing a winter coat, long pants, and a gas mask. Your body goes into overdrive trying to meet the demand you need to be comfortable. However, it simply cannot keep up and you put your health in danger (do not attempt this, just visualize). The same thing goes for your HVAC system. When the coils are not cleaned they are essentially running with a gas mask on, reducing efficiency, increasing costs, increasing the likelihood of breakdown, and decreasing comfort conditions inside. ASHRAE (American Society of Heating, Refrigeration, and Air-Conditioning Engineers) conducted a study on the financial benefits of cleaning coils. The article that shares the research and findings is called Study Verifies Coil Cleaning Saves Energy. As always, a link to the article is available at the conclusion of the post. The title does not leave any mystery as to what the results of the study are. However, since I realize many people need to see the backup for such a claim, I will give you the hard facts. One of the first paragraphs in the article really hammer home the importance of proper coil maintenance, and sets the stage for the rest of the article.
"We believe we found a methodology and regimen that proves maintaining air handler components in a clean condition can save energy dollars and improve other building parameter changes and efficiencies such as improved dehumidification and comfort, along with less mold and bacteria. Thus, we are encouraging IAQ environmental parameter improvements, better tenant satisfaction, and increased worker effectiveness"
The study was performed at a 34-story building in Times Square, New York and was conducted by essentially measuring performance of air handlers before and after coil cleaning. Some of the findings from the research are as follows:
- Improvements that will lead to energy savings of up to $40,000 in the year of the study
- Increased thermal efficiency of coil by 25% with respect to ability to transfer its energy to its sensible loads
- Increased thermal efficiency of coil by 10% with respect to ability to transfer energy to its latent loads
- Good maintenance and operation practices can significantly improve energy efficiency and IAQ performance of HVAC systems in a building by 10%-15%
I'd like to share with you two photos before wrapping up this post. The first photo below is what a clean condenser coil looks like.
This coil does show some signs of wear, but is overall clean and operating efficiently.
The coil to the right is extremely dirty and will not be operating efficiently.
To conclude, I hope the data and pictures speak for themselves. A unit that is maintained properly is a unit that operates efficiently, and a unit that operates efficiently is one that operates at a reduced cost. With cooling season approaching quickly, make sure you building's "winter coat" so that it can breath and enjoy the warmth as well.

Managing Energy Costs in a Hospital Setting
I am constantly on the look out for literature, articles, or other blogs that will allow me to learn as much as I can about this industry. I am a fervent believer than in order to best serve my customers, I must always be a student to trends, challenges, and how these systems work. I spend time each week feeding this thirst for knowledge, and this week's search lead to a topic that I have some personal connection to. The research article from www.esource.com that I used to write this blog focuses on managing energy costs in hospitals, and the link to that article is at the conclusion of the blog.
My fiancé and mother are both nurses, and my fiancé works at one of the largest hospital systems in Virginia-VCU Health Systems (previously MCV). Whenever I go visit her for lunch I am amazed at the complexity of the infrastructure and the magnitude of the campus. It is hard not to notice the hospitals presence in the skyline coming in and out of the city, and I often wonder what it takes to operate on a facilities level. Upon reading the facts, figures, and data in this article I feel I have a surface-level understanding of how much goes into keeping these facilities operating so that they can save and repair lives.
There is an immense amount of equipment and systems that consume energy in a hospital. The U.S. Energy Information Association (www.eia.gov) states that a 200,000 square foot, 50-bed hospital spends $680,000 on electricity and natural gas. That is roughly $13,611 per bed. Let that sink in for a second. For comparison, VCU Health Systems has approximately 780 beds throughout the facility. Wow! Does that figure floating in your head shock you as much as it does me? Does that help put health care costs into perspective a little bit? (That's another topic completely...) With energy costs consistently and exponentially rising, how can hospitals reign in consumption and combat horrid utilities bills?
Before a plan can be made to manage costs, one must understand where the costs are coming from. Below is a breakdown of where the energy goes by percentage:
Electricity: Natural Gas:
Water Heating: 1% Cooking: 4%
Office Equipment: 1% Other: 9%
Space Heating: 3% Water Heating: 30%
Refrigeration: 3% Space Heating: 57%
Computers: 4%
Cooling: 14%
Other: 15%
Ventilation: 16%
Lighting: 43%
We a baseline of consumption laid out, we can begin to take a look at cost reduction. There relatively inexpensive strategies that are more geared towards immediate impact, and there are long term strategies that could potentially involve substantial capital expense, but drastically increase energy efficiency. I am going to focus my thoughts on the more immediate strategies.
A common practice in my household, as I am sure it was in many others, as a kid was to "turn the light off when you're not in the room." Well, it's a theme that can be simple to implement and effective in reducing consumption and in turn-costs. The article suggests posting "Please turn the lights off when not needed" stickers above light switches. The hospital could implement a "green" initiative that rewards units or departments for showing a reduction in energy consumption, if that is something that is monitored on that level. Still in reference to a "green" initiative, a campus campaign utilizing signage, email blasts, and social media could be effective, yet inexpensive, in promoting conscious lighting usage. De-lamping, where light bulbs where the is excessive lighting are physically removed, could also be a method employed. The installation of lighting controls, if none exist, is an excellent way to curb overuse. Automatic controls utilize sensors, timers, and dimmers to save energy and reduce maintenance costs.
Aside from lighting reduction, powering down computers and effectively utilizing sleep mode for desktop computers can be helpful in reducing consumption. Energy Star Power Management program (www.energystar.com/index.cfm?c=power_mgt.pr_power_management) provides free software that places active monitors into a low-power sleep mode through a local area network. Once again, a simple and inexpensive solution that can amount in substantial savings.
The HVAC systems in hospitals are typically responsible for 33% of the electrical consumption, and 56% of the gas consumption. It is my experience, and it is noted in previous posts, that many organizations underestimate their HVAC systems. However, the numbers speak for themselves-this equipment needs to be recognized as a massive asset to be protected. Inversely, this equipment is can also be a liability if not kept up with. Regularly schedule maintenance and tune ups save energy and extend the useful life of the equipment. Tasks such as coil cleaning, equipment calibration, component inspection and replacement, filter changes, etc. will ensure equipment operates as efficiently and effectively as possible. By establishing the correct preventative maintenance program, energy cost reductions of between 10% and 20% could be realized on the HVAC equipment alone.
In addition to creating a preventative maintenance plan, there are a few other areas within the HVAC realm that can result in more effective energy cost management. Many air conditioning systems utilize an economizer. An economizer is a dampered vent that draws in cool outside air when it is available to reduce the need for mechanically cooled air. Through periodic inspections to ensure the linkage is operating correctly, the likelihood of the economizer being stuck in the fully opened position decreases. If that issue occurs, there is a constant flow of outside air coming into the system-regardless of the need. This will result in the need for mechanical conditioning to bring the air to the requested temperature. You guessed it-that inflates the energy consumption, and negates the purpose of the economizer. When it comes to the chilled water system, facilities can sequence the chillers on and off and operate multiple cooling towers can make the most of the systems and operate in the most energy efficient method.
To conclude, these systems are a testament to human ingenuity and innovation. I am constantly amazed at how the technology comes together to work effortlessly at the push of a button. I can see components of this complex system every day on my way home from work and I now have a deeper understanding of the impact it has on the hospital. I've outlined the expenses incurred, and I've given a couple ideas of how to reduce consumption and cost. What I haven't done yet is put the impact into perspective. My responsibility to clients is to develop proactive methods to reduce their operating costs and expenses. In many cases this results in an increase in net profits, which is great-that is the goal in business. In a setting such as this, a not-for-profit health care center, that responsibility transforms into something completely different. Each dollar of operating costs we can reduce is another dollar that can go towards researching cancer treatments, obtaining rehabilitation tools and resources, or improving patient care and experience. I hear about the back-end of those improvements from my family and the people they help. Knowing that I had a small part in making that happen is a satisfaction that cannot be put into words.

Challenges in Preserving History
Yesterday morning upon arriving to the office, my brain at full power from the copious amounts of coffee, I had a completely different topic for the blog entry I am writing now. However, one of my meetings yesterday inspired me to switch it up and discuss something completely different, so the other topic will just have to wait!
As my "about me" section states, I love the city of Richmond. The rich and deep history that is all around us is inpsiring and thought provoking. I live in an old house just a few blocks from where Patrick Henry gave his famed "Give me liberty or give me death" speech. I constantly find myself thinking about how life was at that time in my neighborhood, and it absolutely fascinates me. There is a tremendous amount of history throughout our state, and I had the opporunity to spend some time with an organization that is doing a fantastic job preserving the history of their town and educating others in the process. It was a great experience on many levels. Professionally, I enjoy the opportunity to meet with a potential client and learn about their operation and if there is something I can recommend that would further push them towards their goals. Personally, I soak in the experience of learning about a new place and the people and events that have shaped it.
When we visit historial sites, museums, buildings, etc. as tourists, I do not feel we have a full grasp of everything that goes in to making that experience happen. How many of us think about how the temperature of the room is affecting the painting we are looking at? Or how the sculpture we are posing beside is reacting to the humidity of the air or the oil from our skins (yes, the signs say don't touch, but I've come to realize people typically do not read well in public settings). What about how the instituion you are visiting is open for business. There is not an endless supply of money in these organizations, and many of them are non-profit-meaning what ever comes in goes right back into the organization. Sure there are grants, donations, and government assistance in some situations but there are many administrative challenges that are created by this financial structure.
I am not a preservation speciliast, nor am I claiming I have all of the answers. However, there are some practices that can be put into place that can help us keep these landmarks around for future generations to learn and explore history.

I am not a preservation speciliast, nor am I claiming I have all of the answers. However, there are some practices that can be put into place that can help us keep these landmarks around for future generations to learn and explore history.
- Temperature Control and Humidity Control:
- As mentioned above, the collections housed in musuems are very vulnerable to the elements-temparture, humidity, human touch, etc. It is extemely important that these factors are reduced as much as possible. It is the reason that many artifacts are enclosed in glass cases, and there are those signs posted near ones that are not.
- ASHRAE, or the American Society of Heating Refrigeration and Air Conditioning Engineers, published a chapter in the ASHRAE Handbook titled "Museums, Libraries, and Archives"that outlines the temperature and humitidy requirements based on the type of facility or collections housed. There is a great amount of information in this publication, which I will not go into great detail about but I highly recommend it. It can be found on ASHRAE's website: www.ashrae.com and there is an abstract of it http://www.getty.edu/conservation/our_projects/science/climate/paper_michalski.pdf.
- Budgeting:
- The need for budgeting is imperative in any business, but especially important for these organizations. Many have set budgets for mechanical system maintenance and repair. From my experience, the budget for repairs are significantly higher than that of maintenance. This is a reactive state of maintenance, and one that is very difficult to budget for as the frequency or cost of repairs are unpredictable. This creates a roller coaster cost situation, and in my opinion is not ideal. I focus on recommending a maintenance plan that allows for consistent budgeting, with the priority being maintenance. This is less costly over time, and is more much predictable when it comes budget time-allowing for the financial focus to be on the exhibits and artifacts.
- Proactive Maintenance:
- Putting these practices together in a cohesive plan or program is the most effective and efficient way to accomplish success. By doing this, the organization will ensure that the mechanical systems are operating at their best, allowing for temparture and humidity control. Equipment issues will be fixed before catastrophic breakdowns occur, putting the collections in harms way and potentially disrupting the flow of the facility. Repair costs are reduced, as the equipment is operating efficienty and small inexpesnsive problems are fixed as opposed to costly repairs. Life of the equipment is extended, leading to less unit replacement over the life of the facility. Simply put, it is the best interest of these organizations to take a proactive approach to their mechanical systems, as they play such an important role in the preservation of history and education.

Welcome!
Welcome to EverythingHVACRVA!
This blog is produced with the hope that I can shed light on current trends facing Richmond, Virginia businesses in the realm of building maintenance, efficiency, and operational costs. This is not a technical blog, rather it is a business blog. The focus will be on how mechanical systems impact the most important thing in any business-the bottom line. It is written for business professionals, by a business professional.
Professionally, I am a Commercial Maintenance Solutions Consultant (mouthful, I know!). It is my responsibility to analyze the current practices and procedures of potential clients with regards to their mechanical systems, learn what they are facing on a day to day basis and how that impacts their ability to perform at their peak, and develop a baseline of their overall operational costs. From there, we develop a plan together to get them exactly where they want to be.
It has been my experience that the mechanical systems are not at the forefront of many business leaders' minds (this experience comes from working with businesses, and also being one of these business leaders in a previous life). Since these pieces of equipment are not often in plain or common sight, they only come to the light when there is an issue-a breakdown, system failure, or temperature control complaints (too hot or too cold). This often leads to a reactive state of maintenance, which can be extremely costly. For one, there is the cost of the actual repair including replacement parts, materials, and labor. Secondly, there could be lost production, or a lack of productivity due to mechanical equipment being offline.
It is imperative that a proactive approach to facility maintenance is adopted by every business out there. In this economy, it is not only the company who produces the best product or service that comes out on top. It is the company that produces stellar goods and services AND proactively manages the cost of doing business.
$1 dollar in revenue hits the bottom line at a fraction of that dollar, while $1 in costs reduced hits the bottom line at 100% of the reduction. This is the idea that drives my process when meeting with the businesses I work with.
