Benchmarking for Compliance with NYC Local Law 84

  1. Energy benchmarking for your building and facilities to ensure complete Local Law 84 compliance.

Building Energy Audit & Retro-Commissioning in Compliance with NYC Local Law 87

Energy Audit

  1. Energy audit and retro-commissioning of base building systems Energy Conservation Measures (ECM), including capital improvements that would reduce energy use and/or cost of building operation.



  1. Inspect base building systems for defects valve operation, damper operation, sensor calibration and programmed set points
  2. Parallel systems checked for even load distribution
  3. Lighting levels measured, and deemed appropriate for their operation.

Energy Audits will be performed by Certified Energy Managers (CEM) or certified High Performance Building Design Professionals (HPBD), Building Energy Assessment Professionals (BEAP) and Registered Design Professionals (PE)

Retro-commissioning will be performed by certified Commissioning Process Management Professionals (CPMP) and Registered Design Professionals (PE)

Answers to Frequently Asked Questions

What is Local Law 87?
The law applies to all NYC buildings over 50,000 square feet and requires a professional energy assessment of the property as well as a "tune up" of its base building systems.
When do I need to comply with Local Law 87?
The date of compliance depends on the last digit of your tax block number. Those buildings with tax block numbers ending in three are required to file an energy efficiency and retro-commissioning report by the end of 2013, those ending in four are required to file by the end of 2014, and so on. The exact schedule is shown below:

Compliance Year











Last Digit of Tax Block











Do you supply out of town services?
We do out of town too...
What are needed to be performed and submitted to the NYC Buildings Department for compliance?
As a building owner, you need to submit two reports before the end of the year.
  1. Energy Audit and Energy Efficiency Report (EER)
  2. Retro-Commissioning and Retro-Commissioning Report
What is an Energy Audit?
An energy audit details a building's energy usage, identifies the systems responsible for this energy usage (heating, air conditioning, lighting, domestic hot water system, etc), and proposes ways to reduce this energy usage. It provides an assessment of the building's base systems including but not limited to boiler and domestic hot water equipment, ventilation, and lighting. Based upon this assessment, an energy efficiency report (EER) is filed with the Department of Buildings. This report includes an inventory of all systems, a breakdown of the energy usage by system, and a list of recommended but not required energy saving measures.
What is Retro-Commissioning?
Retro-commissioning is essentially a "tune up" of the building's base systems. LL87 identifies over 20 items which need to be checked for deficiencies and which need to be addressed if deficiencies are found. Retro-Commissioning requires that certain minor deficiencies in the buildings base systems be identified and addressed. Major, capital intensive repairs such as replacing a boiler are not required. The deficiencies and steps taken to correct these deficiencies will be included in the retro-commissioning report which will be filed with the Department of Buildings as part of the Energy Efficiency Report.
What does the term 'base building systems' mean?
Base building systems are the systems or subsystems of a building that use energy and/or impact energy consumption including: The building envelope ; The HVAC (heating ventilating and air conditioning) systems; Conveying (elevators) systems; Domestic hot water systems; Electrical and lighting systems
Who performs this Audit and Retro-Commissioning?
The law requires the involvement and supervision of a registered design professional (Professional Engineer or Registered Architect) as well as professionals holding specific energy related certifications including but not limited to "Certified Energy Manager"(CEM), "Commissioning Process Certified Professional (CPMP), Buildings Commissioning Professional"(CBCP), Building Energy Assessment Professional (BEAP) and High Performance Building Professional (HPBP).

HRM Engineering Services, PC energy team have all the registrations and certifications required to perform all Local Law requirements, including performing all the engineering and design for recommended system modifications if required.
Do I need to spend a lot of money to implement proposed "energy savings" recommendations?
NO. The recommendations on the Audit and Retro-commissioning reports are not mandatory.
How about retro-commissioning, do we have to spend money on this?
The law requires certain deficiencies be corrected. These include minor deficiencies such as pipe insulation or thermostat adjustments. Capital-intensive work such as, replacing an existing boiler, total building control system, replacement of windows, or a roof systems are NOT required.
Are there any penalties imposed if I fail to comply?
Fines will range from $3000 to $5000 for every year that the building is not in compliance with Local Law 87.
