We would like to bring to our builder and subcontractor’s attention some issues that could occur in the field regarding HERS Verification. The 2016 Energy Code has implemented more and/or tighter regulations when it comes to compliance. Subcontractors need to pay even more attention to the detail of the field installation team. Here are a few suggested items you may want to address with your team:
- Air Flow Testing
- Subcontractors may have issues passing which sometimes is because of the zone system not being adjusted properly. Please make sure your team is pre-testing.
- Refrigeration Charge (RCM)
- Make sure the subcontractors are testing the system prior to the third-party inspectors coming out to verify.
- Equipment Installation
- Make sure the correct equipment is being installed in the correct units and matches the CF1R per plan type.
- High Quality Insulation Installation
- It is becoming common for projects under the 2016 Code to now have a QII verification on the project’s mandatory compliance. The installation must have no voids or gaps and fill the cavity side-to-side, top-to-bottom, and front-to-back. The inspection requires two site visits from the HERS Verification company. One verification is prior to drywall (rough stage) and the other is near final (during all the other verification measures). Please make sure your team is calling us out prior to drywall and following the QII checklist.
- Signing off on the CF Forms
- DuctTesters is a hands-on Energy Consulting Company. We work with, help, train, and follow up with the subcontractors filling out and signing off on the paperwork. Installers are responsible for 100% (each and every home) of respective CF2R documents. There are some areas where trades cross over and issues arise as to who will sign off for what.
- Please note that a builder can always sign off if there are subcontractors refusing to comply. There are items such as a whole house fan where one company supplies it and another installs it.
- There are also areas where QII crosses into drywall and/or framing. Please try to address items prior to work starting by holding a pre-construction meeting and/or list subcontractor cross over area items in scopes of work.
- The forms in the mandatory provider database sometimes only allow one company to sign off on the install. Here are some suggestions of who should sign what form…
Below will have both CF2R & CF3R to complete and sign off:
|HVAC or Electrician
|Indoor Air Quality
|Low Leakage Air Handler (LLAH)
|Quality Insulation Inspection (QII)
|ENV 21, 22, 23
Below will only have CF2R to complete and sign off:
|ENV 02, 03
|Roofer / Framer
(for attic eave vents & radiant barrier)
|Electrician or Lighting
Builders back charge subcontractors for not passing HERS inspections the first time which requires a HERS Verification return trip to pass the second time. It also can hold up a builder’s project to reschedule the subcontractor to fix the mistake and to reschedule the HERS Verification return trip. HERS Inspections are contracted with the builder under sampling protocol. Although we spot check, we process sample groups and provide CF3R documents for each and every home. Our hands are tied if non-compliance is not resolved and/or if installer CF2R documents are not completed.
