Energy Audits & Retro Commissioning

An Energy Audit is a survey and analysis of energy use in a building with the purpose of identifying opportunities to reduce the amount of energy consumed without negatively affecting the operations. Retro-commissioning is the process of ensuring that the energy systems in an existing building are installed as per the design intentions, functionally tested, and capable of being operated and maintained, according to the owner’s operational needs.


Applicable commercial, mixed-use and residential buildings must submit an Energy Efficiency Report (EER) once every ten years. Owners are obligated to submit their EER in the calendar year in which the last digit of the year coincides with the last digit of the building’s tax block number.
