PORTLAND, OR — In March 2008, the New Buildings Institute reported the findings of its study on the energy performance of buildings that had received Leadership in Energy and Environmental Design (LEED) for New Construction certification through 2006, according to the Daily Journal of Commerce.
The report asserted that the energy efficiency of LEED-NC projects as a whole compared favorably (25 to 30 percent more efficient) to un-indexed values of existing national building stock, the article stated.
A more troubling inference of the study is that only 121 of the 552 certified projects at that time were included: Most either declined to participate or had not been tracking necessary energy data, the article noted.
According to the article, in the latest LEED-NC version, certified buildings are required to report energy use for an initial five-year period or risk decertification.
As we attempt to drive energy performance to optimum levels through design and technology, the impact of building operations, in both execution and reporting, will become increasingly critical in providing verification of the value of these measures, the article added.
