New York’s Local Law 87, which goes into effect in 2013, will require insulation upgrades to the piping systems of many buildings.
On December 28, 2009, New York City enacted a new law requiring energy audits and retro-commissioning of many buildings — local law 87. Local law 87 requires many large buildings to “undergo an energy audit every ten years, along with retro-commissioning, to “tune up” the building’s existing systems and ensure efficient operation.”
LL 87 Compliance Summary
Large buildings that are not already LEED-certified, Energy-Star approved, or meet other exception criteria, must take three steps to comply.
1. Energy Audit
Building owners must undertake energy audits to identify energy savings opportunities. The audit covers all base building systems such as HVAC and electrical and must “identify reasonable measures and capital improvements that would result in energy use or cost reductions, the associated savings, cost of implementation, and simple payback period.” The audit must be at least a SHRAE Level 2 Energy Audit and must be performed or supervised by an approved and properly certified energy auditor.
Building owners must also undertake retro-commissioning to correct deficiencies identified in the energy audit. Retro-commissioning must ensure that the building systems meet the criteria identified in section 28-308.3 of local law 87. The criteria include, but are not limited to:
- HVAC calibration and sequencing of hot water and lighting settings
- Cleaning and repair of pipes, HVAC equipment, boiler room components
- Training of maintenance staff and documentation of manuals and permits for HVAC, electrical, and plumbing equipment
The retro-commissioning team must include certain approved and properly certified professionals.
3. Energy Efficiency Report
To complete compliance, the building owner must file an energy efficiency report documenting the energy audit and retro-commission. The due date depends on the last digit of the tax block number; the first emergency efficiency reports (for tax blocks ending in ‘3’) are due in 2013.
Where Insulation Jackets Fit In
Criterion 2.8 in section 28-308.3 of LL87 specifically requires insulation for certain components. Criteria 2.8 states, “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.”
Stay-in-place pipe insulation and pipe wraps may meet the requirements for some simple pipes. However, removable insulation jackets can be the superior choice for pipes and components that require regular maintenance. In addition, many valves and components of highly irregular shape cannot be insulated practically with stay-in-place insulation. Thermaxx provides hot pipe insulation jackets, chilled pipe insulation jackets, and a large variety of valve insulation jackets that can be produced to the exact requirements of those undertaking retro-commissioning efforts for LL87 compliance.
Criterion 2.5 in section 28-308.3 of LL87 requires that, “Steam traps have been replaced as required to maintain efficient operation, if applicable.” We’ve written previously about the importance of properly monitoring steam traps in manufacturing plants. Large buildings reliant on steam heating also stand to benefit greatly from paying attention to steam traps and it seems as though NYC has recognized this in LL87.
–Local Law 87 is a significant piece of legislation to help New York City realize its Greener, Greater Buildings Plan, an aggressive sustainability program targeting the existing large city buildings projected to “reduce greenhouse gas emissions by almost 5 percent, have a net savings of $7 billion, and create roughly 17,800 construction-related jobs over 10 years.”
