Benchmarking A Building For The First Time
Benchmarking a building for the first time requires more work, since property information must be uploaded to the ENERGY STAR Portfolio Manager. The exact information needed changes depending on the type of property, but the Portfolio Manager site will give you a detailed list to simplify the process. The following data is collected for all properties, regardless of their occupancy classification:
- Property name
- Property address
- Total gross floor area
- Irrigated area
- Year built, or planned year for completion when applicable
- Occupancy
- Number of buildings
- 12 consecutive months of energy consumption data
The Portfolio Manager will list any additional information required, based on the type of property. In an office building, for example, the following data is required to calculate an ENERGY STAR score:
- Weekly operating hours
- Number of workers on main shift
- Number of computers
- Percentage of the property that can be cooled
If a building has already been benchmarked, you must only review the information that was previously submitted. If anything about the building has changed, the information on the Portfolio Manager must be edited accordingly.
