Inquiry

The requirement for compliance with SSc7.1 Heat Island Effect Non-Roof Option 2 listed on page 89 of the LEED-NC v2.2 Reference Guide states that "Any roof used to shade or cover parking must have an SRI of at least 29." The first sentence of that paragraph defines "cover" as consisting of any of four possible types of parking cover, of which "under roof" is one of the four choices. From this we would conclude that the only condition with an SRI restriction is "under roof" and that there are no restrictions governing the SRI of cover materials for the other three types of cover, namely; underground parking, parking under decks, or parking under a building. For example, our project has more than 50% of the parking underground (95% of parking is underground). The underground parking is "covered" by a combination of pedestrian-oriented hardscape, vehicle-oriented pavement, and a 65-story office tower. Please confirm the intent of the credit indicates that cover materials for underground parking, parking under decks, and parking under buildings do not need to meet the SRI > 29 requirement and that only roofs covering parking are required to meet the SRI>29.
