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
Sandeep and Carolyn Sood own several apartment buildings in Chicago, but the 55-unit building at 6731 S. Jeffery Boulevard is special. The building is one of the first in the country to receive the new ENERGY STAR® certification for multifamily buildings.
“For us, it’s an important designation. It shows people that want to live here that we care.…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
After the first week, the ductless heat pump and I became so close that could never even think of her as ugly. But some folks don't like the look.
In an analogy to current medical practice, the mini-split heat pump is fabulous but the side effects are minimal for some people. In those cases, we have a cure for the side effect, the LED sandwich light that mesmerizes the eyes softly and makes heat ugly pumps disappear right before your very eyes.…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.
The Appraisal Institute has developed a Residential Green and Energy Efficient Addendum. The Appraisal Institute Green Addendum is the first residential energy efficiency appraisal report addendum developed by appraisers, for use by appraisers when appropriate. This report evaluates items of high performance housing for consideration by appraisers.
Measuring the Value of Home Energy Efficiency
The Appraisal Institute Green Addendum will serve as a tool for…Continue

Remember, though, improvements must have been installed in 2013, not just purchased, and generally, claims can only be made on your primary residence.
Eligible measures may include doors, windows, and…Continue

Electricity comes at a cost. There’s simply no getting around that problem (short of installing your own solar panels, of course). However, that doesn’t mean that you have to be stuck with high power bills. There are several ways that you can reduce the amount of your electricity cost – and they don’t necessarily involve turning off your air conditioner in the middle of summer, either. Here are some excellent ways to knock those costs down.
Get a Smart…Continue

Often, when homeowners make improvements to an existing house, the most important aspects of home performance – including safety, comfort, energy efficiency, durability, and environmental impact – are literally invisible during key steps of any home sale or refinance transaction.
One result is that energy…Continue
Back in the ‘80s, the Center for Neighborhood Technology and others helped the City of Chicago pass a residential utility disclosure ordinance that required the disclosure of heating bills when residential properties are sold or leased in the city. Why? Heating expenses constitute a significant home expense, and it’s important for consumers and Realtors to have access to this information.
Until now, complying with the ordinance could take up to two weeks: a Realtor submitted an…Continue
Energy efficiency can be a tough sell. Providing detailed information about financial savings and environmental benefits doesn’t always motivate conservation. So when rational arguments don’t work, how can we influence energy behavior? Perhaps by creating an emotional response with inclusive and engaging public art installations, such as the upcoming Northeast Green Light Project.…
Here are some warnings about portable air conditioners to help you to be aware of their low energy efficiency rating when purchasing a new air conditioner. If you already have a portable air conditioner or if a portable air conditioners your only option to get some cooling,…Continue
It says something that Ernest Moniz chose to deliver his first public talk as US energy secretary to an energy efficiency crowd.
His appearance last week at EE Global in Washington, D.C. was a surprise of sorts. And the timing was significant. Moniz had only been confirmed as energy secretary three hours before taking the podium at the Alliance to Save Energy’s annual conference.
Why did he make the stop?
Probably not because of the size of the crowd. About 550 people…Continue
Atlanta, Georgia has a reputation for getting pretty darn hot, but it can also get pretty dang cold (No snickering from you Northerners, please!). Believe it or not, Atlantans use more energy to heat their homes than they do to cool them. The design temperature set by …Continue

Solar panels have become more familiar to us in recent years. At one time you would have been hard pushed to find a set of solar panels on a roof near you. Now it is exceedingly common to find these panels adorning roofs all over your local area, even if you don’t yet have them.
Of course as with any other type of technology,…Continue
