A cool roof consists of materials that effectively reflect the sun's energy from the roof surface. Cool roofs must also have high emissivity, which allows them to emit infrared energy.

Energy Efficiency
The practice of using energy resources in an efficient way so as to require less to be used.

Energy Star
A rating system to help consumers compare items that they might purchase.

Scope 1 Emissions 
Direct emissions from owned or controlled sources 

Scope 2 Emissions
Indirect emissions from the generation of purchased energy

Scope 3 Emissions
Other indirect GHG emissions, such as the extraction and production of purchased materials and fuels, transport-related activities in vehicles not owned or controlled by the reporting entity, electricity-related activities not covered in Scope 2, outsources activities, or waste disposal.


SEER
Air conditioner efficiency standard; higher is better.
