A new study from the National Institute of Standards and Technology (NIST) revealed that poor installation of air conditioning and heat pump units often leads to unsatisfactory energy performance. This research took three years to compile, with the help of surveys, field evidence, and various measurements for modeling. The most common installation errors included leaky ducts, improper refrigerant charge, oversizing of systems, and restricted…Continue

“For us, it’s an important designation. It shows people that want to live here that we care.…Continue
One of the most expensive aspects of being a homeowner, other than a mortgage, is money spent toward heating and cooling your home. It becomes a balancing act of sorts, trying to find that perfect comfort level in your home. As many homeowners know, finding that comfort level proves even more difficult with the more people living in your home.
As homeowners we look for every advantage to achieve this comfort level while at the same time trying to save money on our energy cost. This…Continue

It seems that our public schools are constantly in panic mode, looking for ways to save money and allocate limited resources. So it’s particularly exciting to tell you about a project where aerosealing just a single elementary school building is saving one school district about $45,000 a year. That’s a lot of…Continue

In July 2013, the State Board of Building Regulations and Standards (BBRS) voted to adopt the 2012 International Energy Conservation Code (2012 IECC) and ASHRAE 90.1-2010 with MA amendments as the new baseline energy code. The BBRS allowed for the new regulations to run concurrently with the current energy regulations until July 1, 2014. During that time, either set of energy regulations could be used when applying for…Continue

Mini-Split Heat Pumps are Quirky and Still Effective
The name "mini-splits" generally refers to heat pump systems with one outdoor unit and one or several smaller capacity air handlers. The efficiency of their operation comes via the inverter compressor and variable refrigerant…Continue
Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…Continue

It is all ways great advice for small businesses to diversify, I know it pulled our company through a recession and is solely responsible for us coming up on our 20th year in business.

The Residential Energy Services Network (RESNET) announced its collaboration with the International Code Council last week in an effort to help home builders transition to the new 2015 International Energy Conservation Code (IECC). In the upcoming version of the residential building code, RESNET's HERS Index will be an optional compliance path — some people are saying that this compliance path represents the most significant change coming to 2015 IECC.
What is the…Continue
Brainy light bulbs. Refrigerators that heat dishwasher water. Elevators that use no more energy than toasters. These are just a few of the “Oh Wow’ topics last week at the annual EE Global conference.
But it was growth in cities – and their buildings – that was clearly on the minds of industry leaders, 500 in total who gathered at the Washington, D.C. event, sponsored by the Alliance to Save Energy.
The US spends $432 billion per year on energy for buildings –…Continue

Netflix, you were right. I liked Downton Abbey. And thanks, Amazon I do want to read Michael Lewis’ new book. I still can’t figure out how Google knows I have a new dog.
Even if at times it feels a bit eerie, such ‘consumer-of-one’ marketing is a convenience many of us have come to appreciate. And it’s an approach now embraced by most major retailers.
The exception? You’ve guessed it: the ever-old fashioned electric utility.
Nobody is going to just give you free money for helping their cause, right? Well, when it involves energy, there are ways for you to get some money back!
A little research online these days can go a long way, but many people don't make the time. To them I say, "don't be scared, Google, Bing or Yahoo! won't return results that say, 'no'". You can find anything online today with a little work; rebate and incentives you will find.…Continue
