Benchmarking involves measuring meaningful energy usage to determining how a particular building compares to others, and tracking changes over time. The Environmental Protection Agency (EPA) in 2000 launched Portfolio Manager, a nationwide
benchmarking tool that uses energy usage data to provide a score on a 1-100 scale reflecting a building’s performance against comparable buildings. The score is normalized to account for regional differences in climate, operating characteristics, and other factors.
The score can be used to:
- Establish a quick snapshot of a building’s energy performance.
- Target candidate buildings for energy improvement projects.
- Monitor the ongoing performance of a building or a portfolio of buildings over time.
- Communicate with building occupants, management and ownership about a building's energy performance
- Educate landlords and tenants about their building's energy performance compared to other buildings.
