About LL87

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.
