This is a particularly interesting article, written for Fast Company Magazine, as it relates to the current push in many states for a code based energy label for homes.  These labels, often referring to a HERS rating, are based on comparing the energy attributes of a building to the same building as built to current code.  This is also often referred to as an asset rating, as it rates building and not the behavior or actual energy usage.  

While on paper these ratings sound like smart public policy, they are in fact having an unintended consequence, as new homes inevitably have better ratings than older building stock, as new homes are built to current code, the new housing industry has figured out that a HERS rating will in fact drive consumers to buy new home's rather then the existing building stock.  These new homes are generally much larger than older homes (meaning that they may be better than existing homes when compared to code AND still use more actual energy to operate), and of course have major embodied energy, etc.

It is no wonder that, if you have been following RESNET over the last year, there has been a land slide of MOUs with builders across the country.  They realize that a HERS rating will have the impact of driving consumers away from existing homes and into their newly constructed buildings.

I think that as we promote HERS ratings as public policy that there is a real unintended consequence that in many cases may work against our macro energy and environmental goals.

Is It Time To Stop Constructing New Green Buildings?
Making a new building is notably worse for the environment than fixing an old one--no matter how many solar panels you put on it.

By Ariel Schwartz

Step into a new building in certain parts of U.S. and chances are pretty good that it has been built with the environment in mind (and that there is a plaque bragging about it). Maybe there’s natural lighting, a smart HVAC system, or incredible insulation. It doesn’t really matter. No matter what LEED-certified credentials the building can offer, retrofitting the teardown that came before would probably have made more environmental sense.

Preservation Green Lab, a Seattle-based think tank, released a study this week showing that, in the think tank’s words, "the greenest building is the one that’s already built, in almost every case." It’s something that intuitively makes sense, but up until now, the evidence hasn’t been quantified quite to this extent.

The study uses life cycle analysis (a method of measuring impact from cradle to grave) to compare the environmental impacts of reuse and building renovation versus construction over 75 years of use. Preservation Green Lab measured six building types-- single-family home, multifamily building, commercial office, urban village mixed-use building, elementary school, and warehouse conversion--across four U.S. cities with varying climates (representative of Portland, Phoenix, Chicago, and Atlanta).

The results are surprising, if not entirely shocking. It can take 80 years for a new "green" building to make up for the climate impact of its construction process with energy efficient features. If Portland reused and retrofitted all the commercial office buildings and single-family homes it plans to tear down over the next decade, the city could save 231,000 metric tons of CO2. That’s 15% of the country’s CO2 reduction targets for the next 10 years.

The report also presents an alarming statistic from The Brookings Institute: one-quarter of today’s buildings in the U.S. are being demolished between 2005 and 2030, creating massive amount of CO2 emissions. But at least some people are getting the hint. According to the U.S. Green Building Council, most buildings across the world that use LEED certification are now retrofits. Up until December 2011, new buildings claimed more LEED certifications.

There are numerous high-profile examples of LEED retrofits, including the Empire State Building (it expects to cut energy use by 38%) and San Francisco’s Transamerica Pyramid, which saves $700,000 each year in energy costs thanks to an onsite co-generation plant. And yet, there’s still something exciting about a new tricked-out LEED building. It’s a novelty that will hopefully fade with time.

Introducing Green Button
Friday, January 20th, 2012, 12:00 pm Eastern Time

Webinar Description:

U.S. CTO Aneesh Chopra challenged the industry to spur rapid and consistent development of access by consumers to their electricity usage data. Green Button is the voluntary adoption of an industry standard to empower consumers and foster innovation.

Speakers:

• White House, DOE, and NIST officials will brief attendees on the Green Button initiative.
  
• Other industry presenters are expected on how Green Button is to be implemented and applied.

Cost:
Free to all participants.

The ruling describes the process for considering the proposal and poses a number of issues that will need resolution. The process and schedule for obtaining stakeholder input is described in the ruling, along with lists of questions that we anticipate need to be addressed to establish a record for decision in the coming months down the road.

Please note that there is a series of files in this package that you will find at the following direct link: http://docs.cpuc.ca.gov/EFILE/RULINGS/157047.htm  

The ruling also announces the intent to organize public workshops on Feb. 8-10 to discuss issues and seek to reach better understandings and/or consensus on issues that we think need particular expertise not fully represented by organizations that typically are active parties in our regulatory proceedings (finance organizations, retrofit contractors, ...).
