The International Energy Conservation Code (IECC) constantly evolves to meet current energy efficiency needs. Over the years new requirements have been added to the IECC to make it stricter and increase overall energy efficiency of buildings. Some states are resistant to these changes, and some choose not to adopt an IECC at all. In fact, of the 50 states and the District of Columbia, 10 either haven’t adopted an IECC, or are operating under a code older than the 2006 IECC, according to the…Continue

There has been much ado about the recent paper published by E2e; Do Energy Efficiency Investments Deliver? Evidence from the Weatherization Assistance Program, the final word on which is yet to be written.
Decades of experience and verification prove energy efficiency programs deliver huge benefits to consumers and the environment - and these benefits far exceed the costs. But numbers can be distorted and therein is the bane of Energy efficiency projects.
E2e has some heavy…Continue
I was called in to perform a last minute duct test for a modular home builder. He was all in a dither to have a duct test and a blower door test done on a Friday so that he could get his Certificate of Occupancy (CO) so the homeowner could move in the following Monday. He said that he’d just found out that he needed these tests. The building inspector asked for them at the last minute!
I was glad to do it partially because it’s good to have builders aware of what is going on…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.

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

Homeowners are often aware of the different problems they experience in their homes: uncomfortable rooms, high utility bills, poor indoor air quality, etc. However, homeowners are generally unfamiliar with the concept of Home Performance, the Whole House approach, and how energy efficiency upgrades can address these concerns. We regularly hear these stories and find that by listening, asking the right questions, educating, and providing guidance, we can help homeowners feel…Continue

The WiFi revolution.
Retrotec and The Energy Conservatory - the two giants of pressure diagnostic tools- collaborated to show us the future. A future…Continue

Energy is needed everywhere – be it industry, agriculture, homes, buildings, infrastructure or services. Even as we grapple with the twin-headed monster of rising energy demand and ravaging carbon emission, we are only left with Hobson’s choice – the need to manage energy efficiently.
