Can USGBC Improve the Performance of LEED Buildings by Collecting More Data?

Mireya Navarro’s recent piece in the New York Times about the energy performance of LEED buildings does not really shed much new light on a topic that many of us have been paying close attention to for the past two years, particularly in the aftermath of the controversial New Buildings Institute study that claimed LEED buildings performed, on average, 25 percent better than the CBECS database. Nevertheless, Navarro’s piece seems timed to coincide with USGBC’s press release of August 25 that announced a new Building Performance Initiative which will complement the LEED Version 3.0 Minimum Program Requirements’ ongoing performance data reporting obligations in order for projects to maintain their LEED rating and avoid the unsavory potential consequences of decertification. Any commentary on this press release – at least in the blogosphere – appears to have been lost in the August doldrums, but I think it is worthwhile to consider an effort which could ultimately have major repercussions for the underpinnings of the LEED system itself. However, many building scientists will tell you that simply collecting more data does not necessarily translate into improved performance. Consider (after the jump) the following letter that was submitted to the New York Times by ASHRAE Fellow and Distinguished Lecturer Larry Spielvogel, P.E., in response to the USGBC press release announcing the Building Performance Initiative, which Mr. Spielvogel was kind enough to allow us to reprint here at GRELJ.
