SS c7.1: Heat Island effect—Non roof
To reduce heat islands to minimize impacts on microclimates and human and wildlife habitats.
Use any combination of the following strategies for 50% of the site hardscape (including roads, sidewalks, courtyards and parking lots):
Provide shade from the existing tree canopy or within 5 years of landscape installation. Landscaping (trees) must be in place at the time of occupancy.
Provide shade from structures covered by solar panels that produce energy used to offset some nonrenewable resource use.
Provide shade from architectural devices or structures that have a solar reflectance index 2 (SRI) of at least 29.
Use hardscape materials with an SRI of at least 29.
Use an open-grid pavement system (at least 50% pervious).
Place a minimum of 50% of parking spaces under cover 3. Any roof used to shade or cover parking must have an SRI of at least 29, be a vegetated green roof or be covered by solar panels that produce energy used to offset some nonrenewable resource use.
Potential technologies & Strategies
Employ strategies, materials and landscaping techniques that reduce the heat absorption of exterior materials. Use shade (calculated on June 21, noon solar time) from native or adapted trees and large shrubs, vegetated trellises or other exterior structures supporting vegetation. Consider using new coatings and integral colorants for asphalt to achieve light-colored surfaces instead of blacktop. Position photovoltaic cells to shade impervious surfaces.
Consider replacing constructed surfaces (e.g., roof, roads, sidewalks, etc.) with vegetated surfaces such as vegetated roofs and open grid paving or specify high-albedo materials, such as concrete, to reduce heat absorption.
Parking under cover, and 100% of the base building on-site parking is located underground or under cover.
Total parking spaces: 07 spaces
Parking spaces under cover: 07 spaces
Qualifying parking spaces: 100%
Roof materials of Parking: SRI = 78
