Local Law 87 Corrective Measures

Local Law 87 Retro-Commissioning

To keep it Simple… Retro-commissioning is essentially a “tune up” of the building’s base systems. LL87 identifies 28 items which need to be checked for deficiencies and which need to be addressed if deficiencies are found its that simple.

Local Law 87 is both a useful and onerous requirement for NYC owners and managers. The process helps to identify energy savings, but the costs of compliance can be significant. Platinum Energy Groups is better than anyone at closing the gap between the problems and the benefits that this law creates because we not only assist other commissioning agents but performs the necessary corrective measures in-house with our own personnel.

Local Law 87 requires that all New York City buildings greater than 50,000 square feet undergo a professional energy assessment and that the results of this assessment be filed as a report with the New York City Department of Buildings. The law is divided into two components:

Energy Audit Requirement

An assessment of the building’s systems for the purpose of identifying recommended but not required energy savings measures. The recommended measures are to be provided in a report to the building owner and filed with the New York City Department of buildings.

Retro-Commissioning Requirement

An assessment of the building’s base systems for the purpose of ensuring that a building’s systems are operating as intended. Local Law 87 lists 25 “retro-commissioning items” relating to the building and its operations. Items found to be deficient are to be provided in a report to the building owner and corrections can be done in-house or with Platinum Energy Groups Services. The deficiencies and steps taken to correct these deficiencies are to be filed with the New York City Department of buildings. Compliance is Easy with PEG…

The Retro-commissioning measures required to be performed at minimum and filed in the Energy Efficiency Report

  1. Operating protocols, calibration, and sequencing:
  2. HVAC temperature and humidity set points and setbacks are appropriate and operating schedules reflect major space occupancy patterns and the current facility requirements.
  3. HVAC sensors are properly calibrated.
  4. HVAC controls are functioning and control sequences are appropriate for the current facility requirements.
  5. Loads are distributed equally across equipment when appropriate (i.e. fans, boilers, pumps, etc. that run in parallel).
  6. Ventilation rates are appropriate for the current facility requirements.
  7. System automatic reset functions are functioning appropriately, if applicable.
  8. Adjustments have been made to compensate for oversized or undersized equipment so that it is functioning as efficiently as possible.
  9. Simultaneous heating and cooling does not occur unless intended.
  10. HVAC system economizer controls are properly functioning, if applicable.
  11. The HVAC distribution systems, both air and water side, are balanced.
  12. Light levels are appropriate to the task.
  13. Lighting sensors and controls are functioning properly according to occupancy, schedule, and/or available daylight, where applicable.
  14. Domestic hot water systems have been checked to ensure proper temperature settings.
  15. Water pumps are functioning as designed.
  16. System water leaks have been identified and repaired.
  17. Cleaning and repair:
  18. HVAC equipment (vents, ducts, coils, valves, soot bin, etc.) is clean.
  19. Filters are clean and protocols are in place to replace, as appropriate.
  20. Light fixtures are clean.
  21. Motors, fans, and pumps, including components such as belts, pulleys, and bearings, are in good operating condition.
  22. Steam traps have been replaced as required to maintain efficient operation, if applicable.
  23. Manual overrides on existing equipment have been remediated.
  24. Boilers have been tuned for optimal efficiency, if applicable.

Exposed hot and chilled water and steam pipes three (3) inches or greater in diameter with associated control valves are insulated in accordance with the standards of the New York city energy conservation code as in effect for new systems installed on or after July 1, 2010.

In all easily accessible locations, sealants and weather stripping are installed where appropriate and are in good condition.
