But, it could affect your ability to receive ENERGY STAR certification because there are minimum occupancy requirements for certification for these property types:
- Office/Bank/Courthouse/Financial Center – 50% occupancy required
- Hotel - 55% occupancy required
- Multifamily – 75% occupancy required
