New York City, in compliance with Local Law 32, has adopted the NYStretch Energy Code as the basis of the 2020 New York City Energy Conservation Construction Code. As a whole, the NYStretch Energy Code includes significant increases to building energy efficiency that are anticipated to be 11% more efficient than the 2020 NYSECCC.
Below is a non-comprehensive list of changes to the code for both residential construction projects (one- and two-family dwellings, townhouses, and multi-family buildings 3 stories or less) and commercial construction projects (any buildings not defined above as residential, including multi-family buildings 4 stories or more).
Lighting/High Efficacy Lamps
The required minimum percentage of high efficacy lamps (light bulbs) increased from 75% to 90%.
An ERV or HRV is recommended however there are exceptions for balanced ventilation systems that utilize an exhaust fan and a duct connected to the return side of the air handler. Mechanical ventilation is now required to be tested by an approved agency.
Thermal Bridges on Construction Documents
Construction documents required to include documentation of thermal bridges that were not pre-calculated in assembly U-Factors outlined in Appendix A of ASHRAE 90.1-2016.
HVAC Duct Location
Required that all ductwork to be in conditioned space. The ductwork can be located in unconditioned space if all of the following are met.
Hot Water Distribution Systems
Hot water systems distribution system are required to meet one of four energy efficiency requirements; maximum allowable pipe length, maximum allowable volume, drain water recovery, or recirculation system.
Electrical Vehicle Service Equipment
One- or two-family dwellings and townhouses with parking area provided on the building site required to provide a 40-amp outlet in the parking area or panel capacity and conduit for an outlet.
Energy Reduction Index Requirement
The Energy Reduction Index (ERI) is an alternative pathway for energy code homes required to achieve an ERI of 50 from 54.
Insulation and Fenestration Performance
Typical envelope assemblies have increased insulation requirements that all project teams should review early in design. Additionally, balconies and parapets are required to have continuous insulation in coordination with the wall assembly that they interrupt OR include an R-3 thermal break.
Fenestration performance increased significantly, and a provision was added increasing the performance even further for fenestration installed 95 feet high and above.
Blower Door Testing
The NYCECC expands on blower door testing requirements for commercial buildings. Now all new construction and additions greater than 10,000 sq. ft. and less than 50,000 sq. ft. and less than 75 feet in height are required to complete blower door testing.
Instances of thermal bridging are required to be clearly indicated in construction documents.
Whole Building Energy Monitoring
New provisions have been added that require all new buildings over 25,000 sq. ft. and all multifamily buildings with 10,000+ sq. ft. of common space to install measurement devices capable of individually monitoring natural gas, fuel oil, propane, steam, chilled water, and hot water. Additionally, these buildings are required to install a measurement device that can record electrical energy use every 60 minutes.
Lighting Power Densities and Lighting Controls
Lighting power densities have been decreased by approximately 25% to account for the widespread adoption of LEDs.
Lighting control requirements have become more stringent in several ways.
New York State adopted the 2020 New York State Energy Conservation Construction Code (NYSECCC) on December 6, 2019 and it is effective as of May 12, 2020. The 2020 NYSECCC references the 2018 International Energy Conservation Code and ASHRAE 90.1-2016 with amendments.
The 2020 NYSECCC mostly makes incremental improvements to the previous energy code version. Below is a non-comprehensive list of the major changes for both residential construction projects (one- and two-family dwellings, townhouses, and multi-family buildings 3 stories or less) and commercial construction projects (any buildings not defined above as residential, including multi-family buildings 4 stories or more).
