Blower Door Test Requirements in Denver
Since the adoption of the 2015 IECC Residential Energy Codes, blower door air leakage testing is now a requirement for most construction projects in the Denver Metro area. This includes new construction and renovations where the addition is 30% or larger than the original home.
ACH Requirements for Residential Blower Door Tests
- Single-family homes – 3 air changes per hour (ACH) or less.
- Townhomes with attached common walls – 4 ACH in Denver County.
- ADUs – 4 ACH in Denver County, different for all municipalities.
- Additions – Required for additions that are more than 30% of the original square footage of the home, not including the basement. A pre-test is performed to determine the air leakage of the original home. This ACH number is the benchmark for the final test post-construction. The final test must be less than or equal to the pre-test. Performing a pre- and post-test is much easier to pass since there is no specific ACH required to pass. If a pre-test is not conducted, then 5 ACH or less is required. We highly recommend that you perform a pre- and post-test to increase your chances of passing.
- Attached multi-unit testing – To aid in passing your air leakage testing on attached homes, we use multiple blower door fans to isolate the shared interior walls. This is called guarded testing. By running multiple blower doors at the same time, we are able to determine the leakage to the outside of individual units negating leakage between units through shared interior walls.
How Much Does a Blower Door Test Cost?
We offer cost-effective pricing for blower door tests. We charge:
- $225.00 for single tests
- $200.00 for additional tests
Pass Your Blower Door Test the First Time!
Failing a blower door test can be expensive and delay timelines. Our pricing includes a framing inspection to pinpoint potential areas of air infiltration before testing begins. This increases your chances of passing on the first attempt, keeping your project on schedule and on budget.
If you are unable to pass your blower door test, we use infrared imaging and zone pressure diagnostics to determine where you are having air infiltration issues so you can address them. We will continue to work with you until you are able to pass your blower door test. Additional testing is $200 per test with 1.5 hours of diagnostics included; additional diagnostics time is charged at $25 per 15 minutes.
