C-NY-2 Comfort and Quality: Commercial Building Thermal Envelopes Part 1

COURSE DESCRIPTION

This course will take a deep dive into the requirements for the building thermal envelope in Section C402 of the 2025 Energy Conservation Construction Code of New York State. Part 1 will specifically look at the changes between the 2020 ECCCNYS and 2025 ECCCNYS, as well as the updates to the prescriptive insulation and fenestration requirements, and air barrier, air sealing, and insulation installation criteria along with the requirements for air leakage testing.

LEARNING OBJECTIVES

1. Compare the minimum prescriptive insulation requirements for the 2020 ECCCNYS and the 2025 ECCCNYS.

2. Identify the insulation levels required by the 2025 ECCCNYS for above grade walls, floors, ceilings, slabs and foundation assemblies.

3. Recognize the benefits of air barriers and air sealing the thermal envelope.

4. Describe the air leakage testing requirements in C402.6.2.
