A revision was made to the Global Alternative Compliance Path supplement to the LEED 2009 Reference Guide for Green Building Design and Construction. For credits SSc7.1 Heat Island Effect Non-Roof and SSc7.2 Heat Island Effect Roof, this revision provides more options for credit compliance in locations where product manufacturing data is not readily available. The guidance introduces new strategies to achieve the credit requirements by including more guidance related to in-place testing, lab testing, and using data from a previous project to achieve the credit. The guidance also includes an expanded list of resources for global teams to reference when pursuing these credits.
