Yes. You can apply for ENERGY STAR certification as long as the property maintains an average occupancy at the required level for the 12-month period of assessment.
These property types have minimum Occupancy requirements:
- Office/Bank/Courthouse/Financial Center must be at least 55%
- Hotel must be at least 60%
- Multifamily must be at least 80%
- Schools must be open at least 8 months out of the year (not technically occupancy though)
All other property types do not have specific Occupancy rate requirements. However, some Use Details have minimum annual values to allow a score to be generated. For example, Office properties must have Weekly Operating Hours of 30 hours or higher to receive an ENERGY STAR score.
