Aerators

Aerators are attached to faucets and showerheads to mix air into the water stream, maintaining pressure and reducing water usage.

Albedo

Albedo is synonymous with solar reflectance.

Alternative Fuel Vehicles

Alternative Fuel Vehicles use low polluting, non-gasoline fuels such as electricity, hydrogen, propane, compressed natural gas, liquid natural gas, methanol, and ethanol. In LEED, efficient gas-electric hybrids are included in this group.

Aquatic Systems

Aquatic Systems are ecologically designed treatment systems in which a diverse community of biological organisms treat wastewater.
