NYSERDA Codes & Standards
Client: NYSERDA
Project Date: 2019-Ongoing
Policy Development and Analytical Support
The Resource Refocus team has been conducting residential codes research and analysis for NYSERDA’s Codes team since 2018. Most recently, the team was selected to lead the 2023 NYStretch residential code development. The project has involved developing code language that specifically encourages electrification and clean energy technologies in new homes, as well as working with stakeholders to ensure the language is clear, enforceable, and aligns with local municipalities’ goals. The team recently completed the energy savings and cost-effectiveness analysis of the residential provisions of the 2020 NYStretch Energy Code. These analyses compare the stringency and cost-effectiveness of different residential code versions for the State minimum code and the 2020 NYStretch Energy Code. Most recently, the analysis has been updated to reflect the rapidly changing landscape of inflation rates as well as material, labor, and fuel costs.
Development of the residential 2023 nystretch and uniform building codes

The 2023 NYStretch residential code development began with evaluation of RFI responses for measures that aligned with energy-efficient and low carbon residential building development, a survey of existing energy codes for simple and effective code designs, and alignment of the previous NYStretch code with new measures that push the code further towards zero carbon buildings. With input from a working group of stakeholders and industry experts, the team has drafted the code language for public comment and will perform a cost effectiveness analysis on the proposed code.

Resource Refocus is also supporting the 2023 New York State Uniform Code development through the identification, prioritization, and analysis of residential electrification and grid interactivity measures.
ENERGY SAVINGS AND COST-EFFECTIVENESS ANALYSES OF THE 2020 NYSTRETCH ENERGY CODE RESIDENTIAL PROVISIONS
Project Team: Resource Refocus
This analysis was conducted to assist with the adoption of the 2020 NYStretch Energy Code. It evaluates the energy savings and cost-effectiveness potential of the residential prescriptive and mandatory provisions of the 2020 NYStretch code when compared to the residential provisions of the 2020 Energy Conservation Construction Code of New York State (ECCC NYS) and the 2016 New York City Energy Conservation Construction Code (NYCECC).
The analysis included a qualitative assessment of code changes proposed by the 2020 NYStretch code, including a determination of which impacts could be quantified through an energy analysis. An energy analysis was then conducted by creating customized energy models tailored to the code requirements for New York State. The energy savings from the energy analysis were combined with the incremental construction costs associated with the changes to determine the simple payback, the 10-year net present value (NPV) of energy cost savings and the 30-year Life Cycle Cost (LCC) savings.
ENERGY SAVINGS AND COST-EFFECTIVENESS OF THE RESIDENTIAL PROVISIONS OF THE 2018 INTERNATIONAL ENERGY CONSERVATION CODE, AS MODIFIED FOR THE PROVISIONS OF THE 2020 ENERGY CONSERVATION CONSTRUCTION CODE OF NEW YORK STATE
Project Team: Resource Refocus
This analysis was conducted at the request of the New York State Energy Research and Development Authority (NYSERDA) on behalf of the New York State Department of State (NYSDOS) as part of an effort to support the 2020 Energy Conservation Construction Code of New York State (2020 ECCCNYS) Rulemaking process. The 2020 ECCCNYS is an energy code published by the International Code Council which is based on the 2018 International Energy Conservation Code, subsequently modified by the NYSDOS.
The analysis includes a qualitative assessment to evaluate anticipated energy impact of code changes proposed by the 2020 ECCCNYS, including a determination of which impacts could be quantified through an energy analysis. An energy analysis was then conducted by leveraging the 2015 IECC DOE/PNNL models to create customized energy models tailored to the code requirements for the State of New York. The energy savings from the energy analysis were then combined with the incremental construction costs associated with the changes to determine the simple payback, the 10-year net present value (NPV) of energy cost savings, and the 30-year life cycle cost (LCC) savings.
