What material attribute would a project team use to compare different products’ abilities to reject solar heat?
A: Solar Reflectance Index (SRI)
B: Emissivity
C: ENERGY STAR label
D: Environmental Product Declaration (EPD)

参考答案: A

本题解释:
正确答案：A
系统解析: A:Solar Reflectance Index (SRI) indicates a material’s ability to reject solar heat and is the combined value of reflectivity and emittance. Measurements vary from 100 (standard white surface, most reflective) to 0 (standard black surface, least reflective). Materials with the highest SRI values are the coolest choices for paving.

LEED requires materials with certain SRI values to meet the requirements of some credits. Materials come with SRI values to allow comparison.

B:The emissivity of a material is the ratio of energy radiated by a particular material to energy radiated by a black body at the same temperature. It is a measure of a material’s ability to radiate absorbed energy.

C:ENERGY STAR labels are for appliances.
