Inquiry

Exemplary performance in Landscape & Exterior Design to Reduce Heat Islands / Non-Roof. Intent: The intent of this proposed Innovation in Design credit(s) is to show exemplary performance as it pertains to Heat Island mitigation. The project is a Campus Dining facility located on a 3 acre site with heavy pedestrian traffic and thru-way circulation. The sought innovation in design is for taking 2 incremental steps above the 30% LEED compliance totaling 98% High-Albedo surfaces across the entire 3 acre site. Design Approach: The project is proposing to use Concrete paving with an initial reflectance of .4-.5 for 98%, or 36,852 sq.ft., of the sites impervious non-roof surfaces. Only 2%, or 863 sq.ft,. of the site will be asphalt paving. Please note also that 18.5% of this already compliant concrete paving will have additional shading by proposed native vegetation. Lastly, the roof surface is covered by a High Albedo LEED compliant roof surface for a total 91% of the roof surface equaling 16% greater than LEED compliance. This makes 65,604.5 sq.ft. of the 3 acre sites total impervious surface of 69,230 sq.ft. constructed with High Albedo materials for a grand total of 95% (this does not include the added benefit of shading by trees 18.5%). Based on the LEED intent for these credits, we feel as though we are good candidates for (2) or more innovation points for exemplary performance. Please advise.
