Residential Energy Efficiency Works. Don’t Make a Mountain Out of the E2e Molehill

American Council for an Energy-Efficient Economy (ACEEE), June 26, 2015, by Martin Kushler.

"The Internet has been burning up these last two days with reactions to a new academic working paper (Do Energy Efficiency Investments Deliver? Evidence from the Weatherization Assistance Program) by researchers at the Energy Policy Institute at the University of Chicago (EPIC) and the University of California, Berkeley, associated with the E2e Project."

Duct Dynasty: Are Smart Vents Really That Smart?

Air Conditioning, Heating & Refrigeration News, May 25, 2015, by David Richardson.

"The concept behind the smart vent goes back to a myth that is decades old. The myth is that if you close the supply registers to rooms you don’t use, you’ll save energy by not heating or cooling those rooms. Sounds logical, right?  To understand some of the interactions these devices can cause with an HVAC system, you have to understand how dampering supply registers affects static pressure and system airflow. It’s also important to know how fans in HVAC equipment respond to these changes in static pressure."

Inverters: Efficient, Comfortable, Quiet: Ductless Technology Moves into Ducted ASHPs

Air Conditioning, Heating & Refrigeration News, May 25, 2015, by Joanna R. Turpin.

"Once the hallmark of high-efficiency ductless equipment, more manufacturers are incorporating inverter-driven compressors into their ducted air-source heat pump (ASHP) offerings. The reasons for this are simple: Inverter technology improves energy efficiency, provides better comfort, and offers quieter operation."

"This report describes the multiple benefits of energy efficiency in multifamily retrofit programs and discusses particular ways of establishing their value so administrators can include them in cost-effectiveness testing."

Defining Indoor Air Quality: IAQ Means Different Things to Different People, Organizations

Air Conditioning, Heating, Refrigeration News, June 8, 2015, by Joanna R. Turpin.
http://www.achrnews.com/articles/129766-defining-indoor-air-quality

The Environmental Protection Agency (EPA), as well as "associations, such as ASHRAE, and individual states, including California and New Jersey, have put forward standards and regulations that address IAQ issues, but the definition of IAQ still remains somewhat nebulous. Perhaps that is because so many factors affect IAQ — everything from poor ventilation and high (or low) humidity to pesticides, mold, and radon. In addition, it can be a challenge to quantify proper IAQ, particularly when occupants in a space have varying tolerances to different contaminants and irritants."

"City authority opens up solar benefits to low-income families through a program of retrofits and new builds."

U.S. DOE Determination Regarding Energy Efficiency Improvements in the 2015 IECC

U.S. Department of Energy, Building Energy Codes Program, May 2015.
http://www.energycodes.gov/determinations#tabs-2

"In May, 2015, DOE issued a determination that the 2015 International Energy Conservation Code (IECC) would achieve greater energy efficiency in residential buildings subject to the code. DOE estimates national savings in residential buildings of approximately:
  • 0.73% energy cost savings
  • 0.87% source energy savings
  • 0.98% site energy savings"

Saving Energy This Memorial Day

U.S. Department of Energy, May 2015, by Erik Hyrkas. http://energy.gov/energysaver/articles/saving-energy-memorial-day

"The first summer holiday is just around the corner, and we know what’s on your minds for your Memorial getaway---fun in the sun, BBQs, and great family getaways to the beach. So how do we get ready for all of the excess fun, and fare with energy efficiency in mind?"
