Brownfield sites land where development may be complicated by the presence or potential presence

of hazardous

substances, pollutants, or contaminants

Heat island effect increase in air temperature in a developed area compared with an undeveloped

area

Solar reflectivity index (SRI) combines reflectivity with emissivity

high SRI values reduce heat gainthe higher the better

scale is from 0-10the lower the better

Albedo reflection coefficient- !lbedo is measured on a scale from zero "for no reflection of a perfectly
