FIELD SERVICES
Residential and Commercial Blower Door Testing
Residential starting at $300
Listed as mandatory in the past 4 energy codes, this test requires the home’s envelope be tested in accordance with ASTM E779 and test at 3 air changes per hour or less. For this test, we will need access to the home as close to move in ready as possible. The test entails the home to be lightly pressurized and the airflow measured. All exterior doors and windows will need to be installed and no major holes in drywall should exist at the time of test.
Duct Leakage Testing
$300 per system
Listed as mandatory in the past 4 energy codes (some exemptions exist). This test requires the duct system to be sealed and pressure tested to show leakage less than 4 cubic feet per minute per 100 square feet of floor area served. While this test can be performed at final, it is in the best interest of the project to test early in the construction process when the system is most accessible.
Diagnostic Testing
$95 per hour
We have a range of tools and techniques for investigating building envelopes and systems to find causes of deficiencies. Ranging from measuring ventilation flow rates, finding gas leaks or assessing insulation performance.
If your project fails the blower door or duct leakage test, we can quickly identify locations to target for additional air sealing. *2 hour minimum
DESIGN SERVICES
Rescheck or UA Alternative
REScheck refers to a software report that is typically supplied to the building department at the design stage of building or renovating a home. The report tells the building department that the project is not being designed to the "prescriptive" path insulation minimums but that the overall building shell is equal to, or better, than the prescriptive path minimums.
RESNET Quality Assurance
Field and File QA reviews as required quarterly by RESNET. Our knowledge base is up to date with the most recent ANSI 301 amendments and interpretations. We work with high and low volume HERS providers on confirmed and sampled ratings.
IECC Plan Review
While not required by most jurisdictions, a plan review is a good idea to help ensure that your project is being designed to meet the minimums and to identify any testing requirements that may apply to your project. A plan review can go beyond energy code to identify potential issues with air sealing, weather barriers, drainage planes, ventilation, HVAC design, occupant comfort and 3rd party program compliance.
COM Check
Commercial building envelope compliance report. This report tells the local building department that the project is being designed to meet the insulation minimums, similar to the REScheck software but for commercial projects.
