NYC Local Law 87 (LL87) mandates buildings larger than 50,000 square feet to submit an Energy Efficiency Report (EER) every 10 years. It reports energy audit results & retro-commissioning measures that validate the operating conditions of building systems.
An energy audit is a survey of energy equipment, systems, envelope and operations in a building. It identifies energy efficiency improvement opportunities and provides recommendations on energy saving strategies. Retro-commissioning focuses on fixing existing systems or equipment. Take HVAC system as an example. As the chart displayed below, more than 40% of a commercial building’s energy is consumed by HVAC system. Therefore, it’s imperative to check the HVAC system’s operating condition and identify any deficiency.
The Energy Conservation Measures (ECMs) uncovered during Retro-commissioning typically involve reprogramming controls, repairing dusty dampers, and replacing faulty actuators, valves, variable speed drives, and sensors. Retro-commissioning also takes a thorough look at how building operators are using the controls, as poor operational procedures usually lead to energy waste. ECMs discovered 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 (which energy audits sometimes do).
According to Local Law 87, the compliance date is determined by the last digit of a buildings’ tax block number. It repeats every 10 years. For example, if the block number ends in 2, the EER report is due by the end of 2022 and the next compliance is due in 2032. Non-submission automatically results in violations, which charge a fine of $3,000 in the first year and $5,000 every year after.
1. Buildings that waste energy can result in high energy costs. The earlier you fix any deficiency, the more you save on energy bills.
2. An energy efficient building increases building and occupant comfort, while maintaining indoor air quality. It improves your building’s value and helps you achieve high occupancy rate.
3. As the NYC Local Law 97 sets limits on buildings’ Greenhouse Gas emissions, it’s urgent to study your building thoroughly and identify any energy waste. Remember, a failure to stay below the limits can result in hundreds of thousands of penalties.
