One aspect of the HVAC industry that I believe many contractors are yet to embrace is that of utilizing comfort as a selling point. And by not doing so, they are missing out on potential business and falling farther behind the leaders of the industry. What I mean by this is that, over the past two decades, understanding of the indoor environment, indoor air quality and the interrelation of building systems has increased dramatically. Think AHRAE 55-2010, and the factors effecting human…Continue
We celebrated Groundhog Day earlier this month. Naturally, that means we held our annual juggling festival here in Atlanta, but some people associate groundhogs with their weather forecasting ability. My question this year was, How can Punxatawney Phil (the weather predicting…Continue
Many pros already know that a standard upgrade is to install a Honeywell IAQ thermostat! That's why you simply must take a look at this analysis on the Thermostat Wars, Honeywell versus Nest, which now threaten to pre-empt even the infamous browser wars, and cause consternation within the industry:…Continue
On Friday, The New York Times published an article titled "In Fuel Oil Country, Cold That Cuts to the Heart." The article, about the Hartford's, an elderly couple in Maine who can't afford to pay for the oil needed to heat their (rather leaky) home, is both heart-wrenching…Continue
What does it mean if the furnace filter collects lots of lint just like what the dryer makes???...Perhaps the dryer is venting inside and the filter is askew and leaks in the return air or filter gap are pulling it into the furnace. Check 'em.
What does it mean if the filter has three-dozen oak leaves pressed onto it?? Today I found an unusually high bill and a handful of foliage fallen from the neighboring trees. In the attic I found a donut of leaves under the vent where the screen…Continue
Nick Magrisso recently posted a blog on the NRDC website highlighting the Carpenter Training Center in Elk Grove Village in Illinois as part of his series of exploratory video blogs on how energy efficiency is creating jobs in Illinois. It has been long recognized that a large amount of energy is wasted through improper or outdated building techniques. In addition to creating jobs,…Continue

This is cross posted from the Energy Circle PRO Blog.
Everyone wants more and better leads, and a lot of people have been asking me recently about Lead Generation Services, particularly since I open sourced the Cost per Acquisition Model for Home Performance Businesses.
No, I’m not thinking of your grandfather’s hand saw . . . the one that cuts on the push stroke instead of on the pull stroke like the excellent Japanese hand saws.
Nor am I thinking of the beautiful (cast aluminum?) circular saws made by Rockwell right here in Syracuse for many years, but long since largely replaced by inexpensive tools made out of plastic and chewing gum.
(There are of course plenty of…Continue
I've made my living solely as a home energy pro since 2004, and I was building a high performance home for two years before that. For six of the past eight…Continue
This is the era of Big Oil. Could the next be the era of Big Efficiency?
A new report by the American Council for an Energy-Efficient Economy suggests the possibility. Re-invented with today’s smart energy technologies, energy efficiency could displace 40 to 60 percent of our total energy needs by the year 2050, according to The Long-Term Energy Efficiency Potential: What the Evidence Suggests.
Sound far-fetched? ACEEE says history backs its…Continue
Vermont has a new comprehensive energy plan that is full of thoughtful - though non-binding and unfunded - ideas. The plan calls for meeting 90% of the state's energy needs through renewables by 2050.
Energy professionals know that it makes sense to dramatically reduce the energy requirements of homes and meet a large portion of remaining needs with renewables. We know how to do the work, what we don’t know is how to pay for it – solar panels and insulation are just…
Please read the article and catch the screen cast at the end of the article.
Earlier in the week, I spoke about construction flaws and how builders have a tendency to build energy waste right into the structure of a home. The contractors really don't mean too, we all understand that, but , never-the-less, poor construction design, short cut methods, and lack…Continue
Americans tend to beat themselves up over their imperfections. We eat too much, watch too much TV and owe China too much money. Despite all of our sloth, we can feel good about one area: our progress saving energy.
A report issued this week by the Institute for Electric Efficiency found that we saved enough electricity to power almost 10 million homes in 2010 (about 112 MWh). That’s 21…Continue
So you have decided you want to earn or become a LEED AP. There is just one small issue, unless you have or are working on a LEED project, just how are you supposed to gain the experience & show documented involvement on a project registered or certified for LEED? (AKA a letter of attestation) As some well know, finding or being able to gain the needed project experience can be a rare opportunity. Fortunately though, the chances for many looking in have an opportunity through a…Continue

So, I was getting ready for my morning bike ride to the coast and decided I needed some calories. Part of my choice was some tortillas. I placed them in the toaster oven and went about my morning. This included drinking my morning coffee and checking my email.
Mmm what is that smell? I had inadvertently put the…Continue
I don’t believe this is an industry specific issue but we do seem to have an excess of acronyms.
For example we have RESNET, HERS, BPI, LEED, CSG, ACCI, ANSI, OSHA, WISHA, OMG, & LMAO!
Confused yet? No – then let’s try these on for size… ACH50, ACHNAT, SIPS, DMHP, HP, WH, HVAC, CFM, ELA, SLA and IECC, MEC, ASHRAE but don’t forget NYC!
BTW can you name EPA, HERC, OSB, PVC, ABS, BD, DB, MDF, MDO, SEER, HSPF, HRV’s, ERV’s, DOE, NGBS, BIA, PV, UV, UVA, UVL, DHW, IAQ,…Continue
2011 was a challenging year for the operators of the Texas electricity grid. 2012, however, isn’t likely to be any easier. This according to ERCOT who holds the responsibility of insuring the reliability of the Texas grid. There are a large number of power plants that are scheduled to be decommissioned over the…Continue
Perhaps the greatest challenge to promoting energy efficiency is that you can’t see it. People understand electricity produced from a PV collector on the roof, and a kWh meter can easily report precisely how much energy was generated. But with more-efficient products, savings cannot be directly measured; instead, one must reckon the difference between a real and a hypothetical situation. This complexity creates a lingering uncertainty whether the promised savings did or did not actually…Continue

Got a phone call from a Son today, he was down at the local Mall looking to exchange a shirt he got for Christmas. This is one of those times when I wish that cell phones would just go away. Why do we need to be in constant touch with everybody all the time?
"Yes son, I bought the shirt there and I don't know why I cut the tag off and I don't know what happened to the…Continue
Passive-solar has been known to work well but certain things about our architecture fail the thermodynamic efficiency test and there are reasons why.
First is heat-transfer through conduction, the wood, drywall, sheathing all having rather high heat-transfer coefficients. Next is convection from a heat-riser which takes the warmth of the floor and moves it to the ceiling.
Until these are dealt with they cost a lot of energy, if one is trying to not require external heating for…Continue
