What is Local Law 87?

Starting in 2013, Local Law 87 requires all buildings in New York City over 50,000 square feet to meet an energy-auditing and retro-commissioning requirement. Compliance deadlines begin Dec. 31 2013.

Audits are performed depending on the last digit of your tax block number. Refer to the chart below:

What exactly do I have to do to ensure compliance?

There are three basic steps to ensure compliance with Local Law 87:

  1. Energy Audit: The energy audit is performed by certified engineers at the building. At its most basic, the audit consists of a comprehensive evaluation of all of the building's energy systems. This can include heating, water, lighting, electric and any other system that may be contributing to the building's overall energy usage. After gathering this information, our engineers construct a thorough audit that evaluates the building's performance and makes recommendations on how to increase energy efficiency and related performance efficiences.
  2. Retro-Commissioning: Using the information gathered from the audit, a retro-commissioning engineer identifies certain deficiencies in the building's base energy systems that must be fixed or upgraded. Typically, these are low-cost to no-cost fixes. The goal of retro-commissioning is to optimize the performance of existing systems without having to completely replace them.
  3. Energy Efficiency Report: This report consists of both the energy audit report and retro-commisioning report. This is submitted to the city's Department of Buildings.

iAG's Energy Audit

has given us a completely new view of how we can save money at our building. Many of the energy upgrades are actually kind of minor in scope and we have already implemented almost half of them. We have already seen savings within the first four months and the residents are happy to be living in a building that is getting "greener" by the day.

iAG Technicians

were extremely quiet and careful while working inside our building. Our building is a hotel, so we were conscious of not making the process an inconvenience for our guests and iAG followed through. Totally professional and will recommend.

Energy auditing proposal was less than half that of the closest firm. The job was done quickly and efficiently and we are now compliant with 87 for the next decade. We know great value when we see it and we would absolutely recommend iAG Energy's services.

iAG Energy's strength

is giving clients a lay-person's understanding of the energy audit results and retro-commissioning process. We were initially not interested in upgrading our energy systems but after consulting at length with iAG engineers it became clear that we could not afford not to upgrade our facilities. Our property group represents over a dozen buildings in Lower Manhattan and they are all scheduled to be audited and recommissioned by iAG.
