    Commissioning for existing buildings, also called “retrocommissioning,” addresses underperforming building systems. At its most basic, this is a tune up of existing equipment to bring its operation back to peak performance. What Taitem adds to this process is an analysis of the current space usage and low/no cost recommendations that will adapt your old systems to the new ways the space is being used. By some estimates, as much as 20 percent of the energy used in an average commercial building is waste associated with poorly commissioned systems. Whether you are considering commissioning on an existing building to comply with NYC LL87 requirements, attempting to get LEED EBOM certification or just want to improve your buildings operating and energy efficiency Taitem can help you.
