RESIDENTIAL LIGHTING DESIGN GUIDE

There are four basic layers of lighting: General lighting, also called ambient, accent lighting, task lighting, and decorative lighting. Measured in footcandles, the IESNA has illuminance level recommendations based on the type of lighting, the type of space, the type of people, and how the lighting will be used (Page 14).

Energy Conservation Building Code-2017

• For qualifying as a cool roof, roofs with slopes less than 20°shall have an initial solar reflectance of no less than 0.60 and an initial emittance no less than 0.90. • Solar reflectance shall be determined in accordance with ASTM E903-96 and emittance shall be determined in accordance with ASTM E408-71 (RA 1996).
