It is everywhere in the media today about “going green” and being more energy efficient in our homes and lives, as well as reducing our carbon footprint and our reliance on oil. For anyone in the energy efficiency field, it is no surprise that a large part of our job is getting the word out about what we do and how the energy assessment is crucial for those that don’t know where to start or what to do. About a week ago, I went to a local “energy efficiency” seminar that was put on by a local HOA (or so I thought) and was excited to see what kind of primer this would be for people interested in making these positive changes. I showed up open-minded and enthused to be around people interested in energy efficiency, but left a bit frustrated when I realized the panel was mainly filled with people pushing their products and not talking about the house-as-a-system approach, or at least helping debunk some of the myths of “green” and energy efficiency.
 

I keep hearing people talk about their high energy bills or condensation on their AC registers, the hot spots in the summer and cold spots in the winter, and of course, the dust and allergens that are prevalent here in Hilton Head and the Southeast. With these problems though, an owner's first thoughts are to call the installers of the products: HVAC, window sales people, insulation contractors, etc... They are not far off, but these subcontractors are probably going to focus on their products and not care how they work together with the rest of the systems. Most HVAC contractors are NOT focused on system peformance and are based in refrigerant charges, amp verification and new compressors. There is more to a home and more to HVAC as they are both systems.

At  the seminar, there was one person who talked about real problems and wasn’t just selling a magic product and that was Paul, a local energy auditor and certified professional. He spoke about airflow and why the airtightness of a house matters. He touched on the diagnostic tools and the process of finding out where you are before you start fixing things, and was excellent in talking about the specifics of infiltration. What bothered me though was the fact that all of the rest of the panel pushed their product and that is what most people heard! We are no doubt a society who craves the quick fix and want fast solutions without having to participate or change!! This type of non-participation is what allows the vultures to feast.

 
After the seminar, Paul spoke to a number of them, and told me later that one man in particular told him, “Thanks for the information” and that he guessed what “he would do is spray foam his house and then call Paul to see what he could do next?!” (More about the problems this creates in a later post and why at least testing your house after foaming is essential for quality control)
 
Paul told him poignantly though that this approach was a bit counterproductive and actually getting him in prior to spraying foam would allow Paul to baseline the house, let him know about the progress after the retrofits, and also ensure that the spray foam was his first logical step. Did this gentleman get it and listen? I don’t know, but if he was searching for that quick fix, probably not.
 
What frustrated me more were the claims that were being made. The spray foam guy stated that you could expect 50% in energy savings from foaming your existing house. WHAT? The HVAC guy said that you could save 10% or so from installing a programmable thermostat. WHAAAAAT??? The window guy ended the night by saying for all those owning existing homes, opportunities were limited and all you could do was change the windows and doors in your house??? What the? I think the window guy was kidding and trying to sell his product like the rest of them, but I don’t think people doubted what he was saying. As we all know, many people mistakenly believe the windows are the best place to start when actually, in many situations, they are not at all! I am so glad there was not a radiant barrier sales person present though, as I may have lost my cool and began heckling for people's sake. All of these products do have potentials, but not to the levels or the simplicity that is spoken to.
 

A little deeper understanding of the seminar was gained the next day though, when it was discovered that the builder who put on the seminar actually has interest in the spray foam company. This builder himself stated that his energy bills were cut in half (YES 50%) from his previous home to his new house due to spray foam. People heard that and I know left thinking this was what they had to do (Paul’s conversations confirmed that this was true). The builder did not once represent that he had a stake in the company and owned the franchise, which in my mind was a little covert. He also never talked about his old 8 SEER unit vs. his 15 SEER unit now (or whatever). Or more importantly his properly sized unit and great ductwork!! He didn’t talk about his high efficiency windows vs. the old single pane aluminum windows (or whatever he had previously). He didn’t talk about his new water heater, appliances, CFL’s, etc…. basically all slices of the pie that make up our utility bill and could weigh apples to apples. This was clear a day later, that he had a mission and that was to sell foam and I think he probably did a good job. What I am getting at here is yes, his bills may have been 50% less at his new house, but it definitely is not from just spray foam, it is due to the system!!

 

The problem I had is this is not the kind of primer course people need on energy efficiency. A lot of people think cutting their lights off will help them the most, or changing out their light bulbs is all they need to do to save money. Although personal habits matter, there is so much more to energy efficiency than just those actions or a single product. Energy efficiency is really fairly simple and all of the “magic” products do have a place in the system, and an important one at that, but they all need to be balanced and considered to make the system perform its best. Each of these products need to be orchestrated properly instead of getting the cart before the horse.

  

I am hopeful, encouraged and invigorated though. I know that it is part of my responsibility, along with other raters and auditors, to get the primer courses out there effectively and non-product biased. We have to get out in front of this wave with good information before people begin making mistakes and hurt all the potential positives that can come from retrofitting these existing houses. I can’t count how many existing homes that have been retrofitted for foam and have horrible condensation problems after the fact due to the spray guy not understanding the envelope, heat transfer, moisture management, and building science basics. We shouldn’t rush and throw around money, we need to allow for a road map to be laid. The hard part about knowing where to end is that you have to know where you are beginning as well, and that is where patience, education and the energy assessment comes into play.

Solar Is a Part of the Solution, But It Needs to be Behind The Horse!

<img alt=For my first blog entry, I have had countless ideas about what to write and how to present what I am doing with my business, the field of building performance and in general what my beliefs are regarding energy-efficiency. Like so many others in this society, I want to get all my thoughts out right away, but I have to remember the saying “Patience is a virtue”. 

High performance building has so much to offer homeowners and occupants. It enables them to live more comfortably and healthier indoors, provides a more durable building, and saves money on lower bills and future costs all while lessening the burden we are putting on our natural resources. This is something that many in the building performance world talk about daily, but once again, as we are a society who craves instant gratification what I am hearing doesn’t shock me, and is something that should change.
 
Whenever I am talking with people about their energy or building related issues and informing them of all the good things from above, they quickly jump to renewable energy, mainly solar, then wind. So this is what I will write about first, my opinion and belief of efficiency first and where these renewable sources fit in the picture.
 
While there is a significant need for renewable energy and they will play a huge role in pushing our nation toward energy independence, they have a place, and I feel it is behind the horse, or inside the cart. Putting up solar PV panels on a house that is energy-inefficient is like putting lipstick on a pig. You will expend lots of energy holding that pig down while you put the lipstick on, but in the end you will still have a pig.
 
Seeing houses that have PV panels on them, but still have 30% duct leakage, or barely any insulation in the attic or walls, makes me wonder why this is happening? Why are people buying these things without taking the time to look at the low hanging fruit? Why are they willing to spend $35,000 +/- without addressing the things that make our lives better first? I think it is fair to say that solar is incredibly subsidized, through 30% tax credits (with no cap) from the Federal Government, as well as local and state incentives to boot and that may have something to do with it. It seems that our government (local, state and federal) are more interested in pushing money through the system quickly and this gives them that avenue. It is not as enticing to have an energy audit and road map laid out for everyone so we know where we are going and  how effectively the money is being spent because that takes too long. Our elected officials want to show that money is coming quickly, so pushing $10K through via a PV panel install, makes them look so much better?! (I don't agree) That is part of our culture (I guess) and something I believe needs to be noticed and changed. With all of the incentives out there, we are doing good, but we could be doing much better. It may take a little more time than just throwing up PV panels, but in the long run it would be WAY MORE BENEFICIAL FOR EVERYONE!! Using a motto of “efficiency first” is what many in the building performance industry believe, and once that is done, solar, wind or whatever has it’s place, just not in front of the horse!
 

Take a look at Mike Barcik’s 5 Step Program for Solar Energy via Energy Vanguard’s blog. I was trained by Mike and Allison Bailes for my HERS certification at Southface Energy Institute in Atlanta, GA and feel lucky to have had two great people that shared the same beliefs of energy-efficiency. It is a great 5-step process and we should take one step at a time. If you are still not convinced, then watch this video from the Florida Solar Energy Center and their approach to solar - this drives Mike's program home!

On a more local level, I live in Hilton Head Island, SC home of great golf, beautiful beaches and rivers, and lots of gated communities. Although many of these communities are fantastic places to live or retire to, they have strict guidelines on colors of paint, types of roofs, styles of windows, and you guessed it, whether you can have solar or not on your house. This surely will change as electricity prices continue to rise and those who live in these communities are smart people that care about the dollar will demand change. Oddly enough though, this restriction could actually be a benefit in the interim. If, or when, the plantation community’s Architectural Review Boards finally change their minds, solar PV will be better and cost less than it does today, and all of those houses (if they followed the 5 step plan) will be ready to size their renewable systems to fit their true needs and not spend any more money than necessary.
 
For those who don’t want to research energy opportunities and only want to come before the horse, they are asking “What do we do to save electricity if we can’t have solar?” That is easy, you can do is the simplest and smartest thing, improve the energy-efficiency of your home. 
 
  • Seal all of those Air Leaks!
  • Seal all of those Duct Leaks!
  • Make it more comfortable by maintaining a constant temperature and proper humidity level within the building. 
  • Make it healthier to live in by improving the indoor air quality. (Sealing those air leaks and duct leaks will help greatly to achieve this.)
  • Change out the old inefficient water heater. The new water heaters, especially heat pump water heaters and the like, are far superior and can have a short payback period vs. the old existing tank. Remember solar thermal, before solar PV!
  • Replace older appliances and of course, change out those incandescent lights for CFL’s or LED’s. They have gotten much better and are coming down in price, and are the future of lighting.
 
The list could go on and on, but as I stated earlier (or told myself) patience is a virtue and patience is also the key to change.
 
We all can do something today whether it is no-cost, low-cost or a something that costs a bit more to make our houses better before just jumping to solar. I look forward to that day solar PV panels go on top of my house, but until then I will pick up the low-hanging fruit and urge you to do the same.
