Energy Code Transition

ReVireo successfully guided design, development and construction professionals in New York through the 2015 IECC transition three years ago. The ReVireo team is dedicated to assisting all New York professionals with the energy code transition to 2018 IECC effective May 12th, 2020.

ReVireo can manage the compliance of your projects from early design through occupancy. ReVireo’s team includes RESNET Certified HERS Raters & Rating Field Inspectors, IECC/HERS Compliance Specialists, AEE Certified Building Commissioning Professionals (CBCP), ASHRAE Certified Building Energy Modeling Professionals (BEMP), and Licensed Professional Engineers (PE).

2020 NYC Energy Conservation Code (NYCECC) NYStretch Energy Code

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).

Residential Projects

Lightning/High Efficacy Lamps

The required minimum percentage of high efficacy lamps (light bulbs) increased to 90% from 75%.

Mechanical Ventilation

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.

  • The air handler is located in conditioned space.
  • The duct leakage is measured to be 1.5 CFM per 100 sq. ft. total leakage when measured at rough or leakage to outside at final.
  • The insulation around the duct is equivalent to the insulation specified in the ceiling.

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.

Commercial Projects

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 are required to complete blower door testing.

Thermal Bridging

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 different ways.

  • The timing for automatic shut-off of lights has been decreased from 20 to 15 minutes
  • Egress illumination and corridors are required to include occupancy sensors
  • The threshold for daylight zone controls has been decreased from 150 W installed in the daylight zone to 100W

2020 New York State Energy Conservation Construction Code (NYSECCC)

New York State adopted the 2020 New York State Energy Conservation Construction Code (NYSECCC) on December 6th, 2019 and it is effective as of May 12th, 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).

Residential Projects
  • Increased prescriptive fenestration requirements for U-Factor and Solar Heat Gain Coefficients (SHGC).
  • Amount of high efficacy lighting fixtures increased to 90% from 75%.
  • The Energy Reduction Index (ERI) threshold for compliance became more stringent in all climate zones.
Commercial Projects
  • Solar Heat Gain Coefficients (SHGC) have been lowered in some instances.
  • Garage doors now have their own thermal performance requirements.
  • Some mechanical equipment, such as room air conditioners, gas and oil-fired furnaces less than 300,000 BTUh and gas and oil fire boilers, have increased efficiency requirements.
  • Water heater efficiencies have been updated to match federal standards.
  • Lighting power densities have been decreased by approximately 20% to account for the widespread adoption of LEDs.
