“Why do we tune up our cars but not our far more complex buildings?” asks Evan Mills, a scientist at the Lawrence Berkeley National Laboratory.  He’s talking about “commissioning,” a basket of techniques for increasing the energy efficiency of buildings:

Energy-wasting deficiencies are almost always invisible to the casual observer, and unfortunately also to building designers, operators, and owners. Commissioning is not a widgit or “retrofit”; it is an integrated quality-assurance practice.

….Back in 2004, the U.S. Department of Energy asked my team at Lawrence Berkeley National Lab to build a national database of commissioning experience….The results are compelling. The median normalized cost to deliver commissioning was $0.30/ft2 for existing buildings and $1.16/ft2 for new construction….Correcting these problems resulted in 16% median whole-building energy savings in existing buildings and 13% in new construction, with payback times of 1.1 years and 4.2 years, respectively.

….Applying our median whole-building energy-savings value (certainly far short of best practices) to the U.S. non-residential building stock corresponds to an annual energy-savings potential of $30 billion by the year 2030, which in turn yields greenhouse gas emissions reductions of about 340 megatons of CO2 each year.

In other words, this is a way of reducing greenhouse emissions significantly — and it’s not just free, it saves money.  It’s a no-brainer, and it’s the kind of thing that will become more widespread if the Waxman-Markey climate bill passes.

It’s also why the cost of Waxman-Markey, despite the pronouncements of the doomsayers, is likely to be close to zero.  The CO2 goals in W-M are actually fairly modest (a 17% decrease from 2005 levels by 2020), and commissioning could provide upwards of a thirds of that at no cost.  Other technologies have similar paybacks, and the net result is that we can almost certainly achieve a 17% reduction at a net cost that’s very, very small.  Things gets tougher after 2020, but that’s also the point at which W-M has provided several years of incentives to develop green technologies that will make further cutbacks considerably less painful than they would be today.  Warts and all, that’s why Waxman-Markey needs to pass.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
