INTRODUCTION The greening of North American building seems to be taking hold.The intended market transformation of the LEED^(TM)Certification system appears to be working.Statistics show that the numbers of certifi ed green buildings in both the United States and Canada are increasing at an exponential rate.The proposed changes to the USGBC version of LEED^(TM)-2009/V.3-are intended to support changes in the system that recognize differences in credit values as well as regionalized differences in the required approach to green building.The introduction of LEED^(TM)for Homes and Neighborhoods has extended the potential infl uence of the program beyond the original commercial building marketing target.ASHRAE’s proposed Standard 189.1 is also taking aim at increasing the standards for high-performance Buildings of a non low-rise residential variety.
