After receiving comments, incorporate them into the answer<br>
and send me the final version. I will post it to the FAQ page.<br>

Hi, everyone,<br>
<br>
I've gotten involved in doing a short write-up for the United Nations Environmental<br>
Programme (UNEP) on the energy savings in the building sector due to the implementation of<br>
building energy standards over the past two decades. My thesis is that although the<br>
theoretical energy efficiency of the building stock has improved significantly over this<br>
period, the actual measurable reductions in energy use intensity has been quite small, due<br>
to the following factors - increased amount of plug loads, and improvements in thermal<br>
comfort in lieu of real energy reductions (the so-called "take-back effect" mentioned by<br>
Mark Modera and others). The bottom line is that although one can say that energy use<br>
intensity in refrigerators have gone down by more than 50%, one cannot simply cannot say<br>
the same in either residential or commercial buildings. At the most elementary level, has<br>
anyone documented the change in EUIs in residential and commercial buildings by vintage<br>
based on data bases such as RECS and CBECS for the entire US, or CEUS for California ? On<br>
a more detailed level, does anyone know of studies that estimated the changes in space<br>
conditioning energy use between buildings built before the standards, i.e., 1970's<br>
vintage, and afterwards, i.e., within the last decade?<br>
<br>
I'm throwing the net wide here, because I need to get some ballpark numbers by this<br>
Friday. Thanks.<br>
<br>

I hope the good folks at GE realize that buildings don't use energy, people do.<br>
<br>
But then, as Winston Churchill said, we shape our environment and our environment shapes us. Maybe Project Frog can influence user behavior to use less energy!<br>
<br>
However, in my humble opinion Project Frog doesn't offer anything new what any architect or engineer who is sensitive to energy use in buildings doesn't offer.<br>
<br>
<br>
