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.

During the first homestand of the season at $1.6 billion New Yankee Stadium, baseballs flew out of the ballpark at an unprecedented rate; the 20 dingers that were clocked during last weekend’s series against the Cleveland Indians were the most ever in a four-game set to open a new stadium in baseball history. Last season, Old Yankee Stadium saw 160 home runs; the current pace would yield a mind-boggling 351 round-trippers for the entire 2009 season. The Yankees did not anticipate that their new ballpark would turn into a Little League bandbox; dimensions at the new park are the same as they were across the street and engineers performed a wind study in advance of construction that did not suggest any major changes in currents or speeds. So, after witnessing several routine fly balls to right field land halfway into the lower deck last Saturday, it struck me that there are some parallels between what’s been happening thus far at the new ballpark in the Bronx and some of the building performance issues that we frequently discuss here at GRELJ.
