Field Lab Green Features

Nearly all (94.28 percent) of the Field Lab roof has an SRI of 29. The USGBC's required value for a steep-sloped roof is 29.

The Solar Roof Index (SRI) is used to evaluate a cool roof. SRI incorporates reflectivity and emissivity properties into one easy-to-read, standardized measure. The greater the surface ability to reflect solar heat, the less heat is transferred into the building, and thus requiring less energy for cooling. SRI is calculated with a complex formula to produce a scale of 1 to 100 measuring the roof's combined thermal properties. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100.
