ENERGY EFFICIENCY RETROFITS.....IN NUMBERS WE TRUST

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…

Embodied Energy: Minimizing Waste with Off-Site Construction

Matthew Wadlund is adding infill housing stock to the Oceanview neighborhood of Berkeley, California, where he is replacing a single-family house with four single-family, three-story detached houses. The wall panels in Matthew's Oceanview Orchard homes are constructed off-site and craned into place, resulting in maximum material efficiency and near-zero waste. Tom White, Home Energy's publisher, spoke with Matthew about his decision to prefabricate wall panels…

Water Conservation

By now you are probably aware of California’s drought. But other states are experiencing droughts—and where there aren’t droughts, there are probably floods. Water and energy consumption are becoming more and more closely connected, and the situation is not likely to improve. Here are some of the ways our clients experience these connections in their homes.…

Energy bills up? There may be humans in your building

Reposted from i.e., the Center for Energy and Environment's Innovation Exchange blog -- http://mncee.org/Innovation-Exchange/ie/

As you read this blog post, what room are you in? How’s the lighting? How’s the temperature? Do you control their levels — or is someone else, somewhere else, running the show? 



About 40% of energy use in the U.S. is consumed in…

Ching’s series of textbook-size volumes go through conceptual to intimate detail of design and construction for both novice and professionals alike. They’re commonly noted as the best and easiest-to-understand references for design…

Unexpected Blessing

When I received an email from Larry Zarker of BPI, informing me that I had been inducted into the BPI Building Performance Hall of Fame, I thought it must be a big mistake. Then I looked at the list of previous inductees and was sure it was a mistake! I haven’t even done a blower door test all by…

Why Don't Homeowners Spend Money on Energy Saving Upgrades??? Blame "Cognitive Biases"

A great transcript from a recent NPR "Morning Edition" broadcast about a recent California survey on water conservation efforts. The results are exactly what we find with energy conservation... When homeowners were asked what actions will save water, most said "taking shorter showers" (turning down the heat), or "keeping water off while brushing" (wearing a sweater) which of course is a complete mismatch of real saving efforts, like installing low-flow toilets (installing insulation).- which…

Revisiting Electrification

I must admit that I am still having trouble getting my head around this idea. But the arithmetic is fairly simple: an 80% reduction in carbon emissions simply can’t be achieved without drastic cutbacks in residential natural gas use. In the residential sector, natural gas burned on site is responsible for about one quarter of carbon emissions. We can use carbon-free electricity generated…
