HUD Energy Efficiency and Weatherization Standards 3

Question 1

What energy modeling software is most commonly referenced for demonstrating compliance with the IECC performance path in HUD-assisted projects?

Accepted Answer

REScheck or COMcheck

Answer

REScheck (for residential) and COMcheck (for commercial) are DOE-developed tools widely used to demonstrate IECC compliance, and are accepted by HUD.

Question 2

According to HUD standards, what is the recommended maximum air leakage rate for new construction, expressed in ACH50 (air changes per hour at 50 pascals)?

Accepted Answer

3 ACH50

Answer

HUD and IECC 2021 target a maximum of 3 ACH50 for new residential construction, and high-performance programs like Energy Star require even lower rates.

Question 3

Which HUD program specifically provides funding for energy and water efficiency improvements to existing HUD-assisted multifamily housing portfolios?

Accepted Answer

Green and Resilient Retrofit Program (GRRP)

Answer

The Green and Resilient Retrofit Program (GRRP) was established under the Inflation Reduction Act to fund energy, water, and climate resilience improvements in HUD-assisted multifamily properties.

Question 4

When a HUD inspector evaluates a building's vapor retarder installation, what is the primary function of a vapor retarder in a wall assembly?

Accepted Answer

To slow the diffusion of water vapor through the wall assembly

Answer

A vapor retarder slows the diffusion of water vapor through the building assembly, helping to prevent condensation within the wall that could lead to mold and structural damage.

Question 5

Under HUD's energy standards, what efficiency rating must a new gas furnace meet to be installed in HUD-assisted housing?

Accepted Answer

80% AFUE minimum

Answer

The federal minimum AFUE (Annual Fuel Utilization Efficiency) for new non-weatherized gas furnaces is 80%, which applies to HUD-assisted housing installations.
