Energy Code Hotline

NYSERDA sponsors a hotline to provide quick answers to questions on interpreting and applying the Energy Code. This service is available five days a week between 8:30 AM and 4:30 PM. Call (518) 377−9410 or E−mail


Duct Leakage Testing - Residential (three stories or fewer)

Section 403.2.2 of the ECCCNYS 2010 specifies that "Duct tightness shall be verified …" This video demonstrates how to perform duct testing using a duct blower.

Energy Code

Know the Energy Code

The Energy Conservation Construction Code of New York State (ECCCNYS) addresses the design and construction of energy-efficient building envelopes and mechanical, lighting and power systems for new and existing buildings.

Commercial Buildings  

Must meet requirements of the International Energy Conservation Code (IECC) 2012, which permits alternative design using ASHRAE 90.1-2010, as modified by the 2014 Supplement to the New York State Energy Conservation Construction Code.

Residential Buildings  

Must meet requirements of the Energy Conservation Construction Code of NYS 2010.

Major Code Changes Effective October 3, 2016! 

On March 9, 2016, the State Fire Prevention and Building Code Council completed major updates to the Uniform Fire Prevention and Building Code (Uniform Code) and State Energy Conservation Construction Code (Energy Code).  Effective October 3, 2016, all buildings must meet the requirements of the IECC 2015, which permits alternative design for commercial construction using ASHRAE 90.1-2013, as modified by the 2016 Supplement to the Energy Code.



Testing Building Envelope Tightness - Residential (three stories or fewer)

Section 402.4.1 of the ECCCNYS 2010 specifies that the building thermal envelope shall be sealed to limit infiltration. How tight do we seal it? The easiest way to demonstrate envelope tightness is with a blower door.

Building Envelope Tightness Visual Inspection - Residential (three stories or fewer)

Section 402.4.2 of the ECCCNYS 2010 offers two ways to comply with air sealing requirements. In this presentation, we look at Subsection 402.4.2.2, the visual inspection option. (The second option is blower door testing covered in a separate presentation in this Resource Library.)

Building Techniques for Code Compliance

In this video presentation series, Rick Arnold, an award winning Energy Star for Homes builder, gives a hands-on overview of the air sealing and insulating requirements of the ECCCNYS-2010. Arnold illustrates specific Energy Code requirements using full-scale construction details and demonstrations.

Moisture Management

In this presentation, we discuss how moisture moves in and out of homes, and explain best practices for controlling moisture problems, including mold.
