What Does Local Law 87 (LL87) Entail?

Local Law 87

Local Law 87, shortened to LL87, is a law imposed by the Department of Buildings in New York City, which requires buildings over 50,000 gross square feet to undertake intensive yet periodic energy audits and retro-commissioning measures. Such a requirement forms part of the GGBP (Greener, Greater Buildings Plan).

This simply means that buildings that are less than the specific gross square feet are safe from this requirement. Typically, the law applies to commercial property owners with large buildings. We know that such buildings contribute significantly to pollutions that buildings are notorious in the United States. Greenhouse gases are attributed to large buildings, and measures are put in place to curb such pollutants.

Local Law 87 addresses the problems of polluting the environment by imposing requirements for large buildings to submit the Energy Efficiency Report (EER) by the due date or face $3000 for the first year and $5000 in subsequent years should you fail to honor the deadlines.

Property owners should contract certified energy auditors or professional engineers and architects to conduct the energy audit and retro-commissioning on their behalf. The Department of Buildings gets convinced that the measures are legit if done by professional engineers and certified agents. As we can help you with the energy audit and retro-commissioning measures. We know how financially crippling the subsequent charges of $5000 could be to your business if you fail to submit the Energy Efficiency Report.

Local Law 87 Compliance Steps

Large buildings (over 50,000 sq. ft.) that are not already LEED-certified, Energy-Star approved, or meet other exception criteria, must take following steps to comply LL87:

  1. Energy Audit

will collect building energy data to suggest capital improvements and system replacements to improve energy efficiency.. Typical measures include lighting upgrade, boiler and HVAC equipment replacement Et.

The audit will be executed and certified by an energy auditor.

  1. Retro-commissioning

We help building owners correct deficiencies identified in the energy audit by performing retro-commissioning and ensuring building systems meet criteria identified in section 28-308.3 of local law 87. The criteria includes and does not limit to:

  • Optimizing HVAC controls
  • Testing, sealing, and balancing ventilation systems
  • Ensuring or installing adequate pipe insulation
  1. Energy Efficiency Report

In the final step of LL87 compliance, we finalize and submit the Energy Audit and Retro-Commissioning reports to the NYC Department of Buildings to attain compliance. The due date depends on the last digit of the tax block number.

When Should You Submit Energy Efficiency Report?

The Energy Efficiency Report (EER) should be submitted once in a 10 year period by the 31st of December as indicated by the last number of your tax number. If, for example, your tax number ends with 9, it means 31 December 2019 is your due date for EER submission. If it ends with 8, it means that 2018, 31 December is your due date.

There should be a legit explanation as to why you miss the deadline. Missing the deadlines comes with financial repercussions. For instance, the Department of Buildings charges you $3000 for the first year and $5000 for subsequent years if you miss the deadlines.

Depending on financial hardships you have, you may ask for extensions from the department. However, such extension application must reach the department by the October 1 of the due date of EER submission. Email the extension application to if you are in New York City. Your state housing department should give you similar provisions. Extension fee is $155.

If your building has earned the U.S. Environmental Protection Agency ENERGY STAR certification two of the three years before the due date of EER, you will then qualify for an exemption from energy audit requirements. The same applies when your building has earned LEED certificate. It will also be exempted from the retro commissioning process. In such cases, you will have to submit the EER only without undergoing energy audit and retro

Conducting Energy Audit And Retro-Commissioning


Energy auditing and retro-commissioning are complex measures that require the technical expertise of professional MEP engineers to accomplish. They are arguably the most cumbersome part of Local Law 87 compliance because without proper assessment you may be asked for costly amendments in your Energy Efficiency Report.

Should the Department of Buildings find discrepancies in your EER, it may request amendments which may cost you $145. It is better to stay out of trouble and request services of a professional engineer to carry out the energy audits and retro-commissioning before you get charged for amendments due to incorrect reports.

To conduct energy audits and retro-commissioning measures, we conduct complex calculations of your energy-consuming systems and recommend the best systems that consume less energy and cost you less. Typically, a expert will be tasked with the service by visiting your apartment for an initial assessment. We will request pre-audit documents such as annual energy bills from you to give us a picture of how much you consume.

Our engineers will visit your building to carry out the necessary audits and commissioning measures. We have been offering all types of building commissioning measures, and so this will not be burdensome or cumbersome for us.

In energy auditing, we will assess how much your appliances consume and other systems. We will then recommend the best alternatives if we realize that consumption is unreasonably substantial. The alternatives we recommend have to be implemented before we compile the final energy efficiency report for submission to the Department of Buildings.

The same applies with retro commissioning where our professional MEP engineer will assess all your building systems’ functionality. This helps map out the best strategy to retrofit best energy-efficient and high-performance systems to curb your annual costs and environmental pollution. Retro-commissioning is of course a comprehensive retrofit process for existing buildings. It may not be as easy as commissioning for a new construction, but worth taking, nonetheless.

What Should The Energy Audit And Retro-Commissioning Entail For EER Submission?

The energy audit and retro-commissioning reports have to be comprehensive and all-inclusive of performance metrics. We have stressed such importance enough now. With a professional engineer, you should not worry about missing any metric because they are well-rounded with such processes and know exactly what to include and how to measure.

Ideally, the audit and retro-commissioning measures should include the following:

  • Overall building information
  • Equipment inventory
  • Energy consumption breakdown
  • Energy optimization methods as recommended by the professional engineer
  • Retro-commissioning metrics

will make sure that the report is all-inclusive of all energy audit and retro-commissioning measures.

The Benefits Of Local Law 87


Although Local Law 87 is mandatory for the covered buildings, it bears massive benefits for building owners. Instead of viewing it as a financial burden, owners should be thankful for this law since it helps them keep track of their buildings’ energy consumption.

Local Law 87 requires energy audits and retro-commissioning measures. This, in turn, helps owners know how much their base building systems consume on a yearly basis so that they can take corrective measures. Without such a mandatory law, property owners seldom consider energy audits until the energy costs impact on their finances extensively. Also, without this law, property owners might be hesitant to consider retro-commissioning of their equipment.

This law helps owners have a deeper understanding of their buildings’ performance. Once you know how much you consume and how much it costs you, you will be able to take measures to optimize your systems. That will be a relief to your yearly energy bills. Also, you will be contributing significantly to greenhouse gas reductions into the atmosphere. Large buildings, the same covered by this law, contribute immensely to greenhouse gas emissions. One might view this law as a government initiative to take a stance against such emissions hence the mandatory requirement of energy efficiency report.

will be glad to carry out a comprehensive analysis of your building systems’ energy consumption and performance. By performing retro-commissioning we are able to spot problematic systems and appliances that need high-performance alternatives. You will then have a high-performing commercial building in the long run. The process is repeated every 10 years, which is the ideal period for the durability of most inventories.

Our engineers can also help you beyond the requirements of the Local Law 87. We can help you with a holistic approach in optimizing your building systems following a retro-commissioning process. Furthermore, our energy audits can help you reconsider renewable energy systems if you do not have them. For example, we are experts in net zero energy, which is an initiative to incur zero costs on your energy bills. This is possible through buildings that produce as much as they consume. Conventional electricity will only incur huge costs in a long run. Let help you reconfigure your energy grid.

Costs Of Local Law 87

Local Law 87 filing fees are not that exorbitant considering the benefits the law yields for property owners. Initially, you have to pay $375 to comply with LL87. Extension and amendment costs are $155 and $145, respectively.

The Department of Buildings will email the instructions on how to pay for a filing fee after you have submitted the EER. Additionally, you have to consider the costs of hiring professional engineers or energy audit agents as per LL87 requirements. A wrong choice could lead to unnecessary costs.

With you are safe from unnecessary exorbitant costs. We offer quality services at affordable services without over-engineering. Moreover, our services are fast-paced than our competitors without compromising quality.

Our engineers can help you keep up with the deadlines. We will conduct the energy audit and retro-commissioning at a faster rate without compromising the quality of course. We will then help you file the EER electronically. Most importantly, we guarantee you the accuracy in our energy efficiency report. Thanks to our experience and expertise.

Can You Compile Energy Audits And Retro-Commissioning On Your Own?

We know that some homeowners are accustomed to DIY services where they supposedly save lots of money. Yes, DIY services save you lots of money but not everything can be fulfilled through DIY. Energy audits and retro-commissioning are complex processes that require the technical expertise of professional engineers to fulfill.

Well, if you are a professional engineer then probably you may consider doing that on your own. Nonetheless, it is better to entrust the services to a professional MEP company that houses highly-qualified and experienced engineers to expedite the process for you. Inaccurate EER can attract $145 worth of amendments as requested by the Department of Housing. Avoid such costs by employing professionals whom you can hold liable should such amendments come.

Similarly, Local Law 87 compliance is complex to be carried out by amateurs in engineering services. The department requires energy audits and retro-commissioning from professional engineers or certified agents. Certified agents also have to pay for certification purposes. Professional engineers, do not have to pay anything. We are automatically qualified to provide these services.
