Option 2. Heat Island Reduction Policies (1 point)

Adopt one of the following city-wide policies for heat island reduction:

a. Cool Roof Policy: Green roof and/or cool roof coatings on low-sloped roofs (2:12 pitch) for new

roofs and re-roofing. Cool roof material must exhibit an initial SR of at least 0.60 and an initial

thermal emittance of at least 0.75 as measured in accordance with ANSI/CRRC S100 .

b. Cool Wall Policy: Cool wall materials in exterior walls must include guidelines for equator opposing walls. Cool wall material must be opaque to sunlight, exhibit an initial solar reflectance

of at least 0.40, and have an initial thermal emittance of at least 0.75.

c. Cool Surface Policy: Cool and permeable pavements for paved open spaces in private buildings

with materials such as conventional asphalt or concrete pavements and other reflective

payments, such as resin-based pavements, colored asphalt and colored concrete, and vegetated

and nonvegetated permeable pavements.
