Mid-2024 Program Changes: What Builders Need to Know

Programs, like the seasons, change at a steady pace. Fortunately, unlike springtime in the Rockies, they are more predictable. Here is a summary of changes and a little bit on what each means to us.

Key takeaways:

Sunsetting of sampling protocol
No longer able to remove sections of drywall for insulation inspection – all drywall must be removed if it’s missed
Less Rater discretion on several topics

It’s important to note that while builders can still achieve ENERGY STAR under v3.1 in 2025, v3.2 is required for tax credit compliance.

Key takeaways:

Sunsetting of sampling protocol for townhouses
No longer able to remove sections of drywall for insulation inspection – all drywall must be removed if it’s missed
Less Rater discretion on several topics
Electric resistance limitations do not apply to heat pumps with integral supplemental or emergency electric resistance heat
A rate of 50 CFM of continuous kitchen exhaust is permitted to be used, rather than 5 ACH, where the exhaust fan or intake grill is located within 10 ft. horizontally of the edge of the range
Common spaces & Central Systems: outdoor air is not required where a building has ≤ 250 ft² of corridor space and does not contain any of the other common spaces which require outdoor air

Key takeaways:

Must use ENERGY STAR MFNC 1.2
2021 IECC insulation requirements for opaque areas
100% high efficiency lighting in dwellings
Builder supplied clothes dryers must be ENERGY STAR
IAP V1 allowed until 1/1/26 then must be IAP V2
H/ERVs in very cold climates (CZ 6-8)
Provide EVSE, EV Capable, and EV Ready spaces for 20% of units or automobile parking spaces with designated capacity and connections as established by the EV-Ready Checklist.
HPWH ready - Dedicated circuit is installed and energized for each installed fossil fuel water heater in a dwelling. Space is reserved for a future electric (heat pump) water heater.
Heat Pump Space Heat ready - A dedicated circuit outlet or conduit, and condensate drain, are installed to facilitate a future heat pump installation for dwellings with installed fossil fuel space heaters.
