SS PREREQ
CONSTRUCTION ACTIVITY POLLUTION PREVENTION
- Sites disturbing 1 acre or more: EPA (MoDNR) require
a SWPPP & NPDES General Construction Permit.
- Sites that disturb less than 1 acre: To meet LEED, must
develop a SWPPP for sites but do not need to get an NPDES permit.
- StormWater Pollution Prevention Plans
- National Pollutant Discharge Elimination System

SS CREDIT 5 HEAT ISLAND REDUCTION
SOLAR REFLECTANCE (SR) The fraction of solar energy (light) that is reflected by a surface on a scale of 0 to 1. THERMAL EMITTANCE (TE) Ability of a material to shed infrared radiation (heat). Values between 0 and 100% SOLAR REFLECTANCE INDEX (SRI) A measure of a constructed surface’s ability to stay cool in the sun - High SR and TE. How to get values…
- SR and TE values from the CRRC-1 www.coolroofs.com
- ASTM E 1980 gives SRI calculations, and there’s an app
for that too!
- Manufacturer’s are making products to meet the LEED
requirements, and publishing data.

- Shade calculated within 10 years of planting
- Use thee-year aged Solar Reflectance SR value
- f 0.28.
- If aged value not available then use SR of 0.33
at installation.
