Effective June 16, 2023
Garfield County has adopted the 2018 International Energy Conservation Code (IECC).
The 2018 version of the IECC features minor changes in insulation values and requires a blower door test to be performed on all new homes to check air-sealing.
Occupant ventilation enforced.
Duct leakage testing enforced if any part of the duct system leaves the thermal envelope.
GarCo will be using the 2021 IECC for multi-family projects; including the provision that lets units under 1500 square feet test for infiltration under the easier surface area metric.
We do that…
Please give us a call and we can help navigate the process in the most cost-effective way. And optimize your construction for performance.
