If you own a building in New York City, you’ve likely heard of Local Law 87 (LL87), which requires an energy audit and examination of building equipment once every 10 years.
The law, and the mandated audit, has two main goals:
1. Let building owners know how their buildings are currently using energy, including any improvements that could be made.
2. Ensure that all equipment (e.g. heating, cooling, water pumps, lighting sensors) is installed and performing correctly.
The law applies to all buildings larger than 50,000 square feet (or two or more buildings on a single lot with a combined total of over 100,000 square feet). Owners must have a certified energy auditor file a report once every 10 years, based on a rotating schedule.
Not just an obligation, but an opportunity to find savings
Although it may seem like just another regulation to meet, Bay Efficiency urges its clients to view this building energy audit as a powerful opportunity to find savings.
The audit will include a detailed inventory of all lighting fixtures and HVAC (heating, ventilating, and air conditioning) equipment and controls. The certified energy auditor will want to see how the building is operating and point out any places where energy is being wasted unnecessarily.
In addition to an energy analysis, the report will also include a financial breakdown. It will show maintenance costs of keeping the building as is — while also showing potential long-term savings that could be realized through energy efficient projects.
How the process works
When it’s your turn for the audit, contact a certified energy and retrocommissioning auditor (retrocommissioning refers to the part of the audit that looks at how your equipment is performing). Bay Efficiency is one of several energy auditors that can help with this process.)
The auditor will come in and conduct the audit to find potential financial savings, let you know about energy efficiency improvements, and ensure that all equipment is working correctly.
Then, the auditor will submit an electronic EER (energy efficiency report). The process is then complete: You won’t need to submit another EER for another 10 years.
In the meantime, you’ll now have the information you need to consider energy savings project and improve the performance of your building.
