Calculate your building’s greenhouse gas (GHG) emissions using EPA’s new ENERGY STAR Portfolio Manager Building Emissions Calculator. This tool allows users to estimate their building’s GHG emissions, support GHG emissions inventories, evaluate emissions under local building performance standards, and forecast the impact of changes in building efficiency and energy procurement.
The calculator:
- estimates past, current, and future emissions
- leverages Portfolio Manager data
- allows entry of multiple emissions factors
- complies with industry-standard GHG accounting protocols
- estimates emissions for a single building or entire portfolios in the U.S.
