NYC LOCAL LAW 87 ‘2009

NYC LL 87 mandates that buildings larger than 50,000 sq. ft. are required to file an Energy Efficiency Report with the DOB. This Energy Efficiency Report includes details of the energy audit results and retro-commissioning measures. An energy audit is an inspection, analysis, and report of energy flows to improve energy efficiency in a building studying building systems (building envelope, HVAC, conveying systems, domestic hot water systems and, electrical and lighting systems. 

While Retro-Commissioning is a detailed look at how well HVAC and lighting controls are working. The Energy Conservation Measures uncovered during retro-commissioning typically involve reprogramming controls, repairing dusty dampers, and replacing faulty actuators, valves, variable speed drives, and sensors. Building retro-commissioning will also take a thorough look at how building operators are using the controls since poor operational procedures usually lead to energy waste. ECM discovered typically are low-cost or no-cost measures. The purpose of retro-commissioning is to optimize existing system performance through fine-tuning and upgrades rather than relying on major equipment replacement.

Your NYC LL 87 deadline is fast approaching, so act NOW or incur penalties!

According to NYC LL 87, the compliance date is determined by the last digit of the building’s tax block number. For example, if the block number ends in ‘3’ that indicates the report is due in 2013, similarly a number ending in ‘4’ would indicate 2014. After filing the initial report on the designated due date, the law requires that the building files an energy efficiency report every 10 years.

Reduce GHG emission and save up to $50,000 every year in energy costs.
