LL87 requires large buildings to audit, retro-commission, and submit information to the City. The audit and retro-commissioning information includes the following:
- Basic team information
- General building information
- Existing equipment inventory
- Energy end use breakdown
- Energy conservation measures identified from the audit
- Retro-commissioning measures
In alignment with annual benchmarking, these measures will work to optimize buildings' energy performance.
