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.
One Innovation Credit for Exemplary Performance is available for LEED-NC Version 2.1 projects that demonstrate 60% or more of the total non-roof impervious surfaces have a reflectance of 0.30 or higher. The project team should consider alternatives to reduce impervious surfaces that could reduce storm water management and heat island while still meeting the hardscape design intent. Utilizing such a design strategy can reduce both heat island and stormwater runoff and potentially increase the project\'s points toward certification. Applicable Internationally.
