Below are the expectations and requirements of the HERS rater to inspect and blower door test. The project must adhere to all drawing sheets indicating air sealing and caulking in the construction set. CONSTRUCTION ADMIN PROCEDURE & REQUIRED VERIFICATIONS: Oakwood Construction will notify Home Energy Services in writing, 1-1/2 weeks ahead of time when the following can be reviewed:

    1) Post framing inspections “before insulation install” HES Review will consist of looking at complete exterior air barrier installation. HES will review and provide a report and identify if corrections are needed.

    2) Pre-drywall inspections “Insulation is installed to proper levels and at Grade I quality” HES will review and provide a report and identify if corrections are needed.

    3) Final performance testing, at substantial completion, including:

    -Air barrier leakage testing (blower door each dwelling unit) -Total duct leakage testing (duct blaster) -Duct leakage to the outside (3rd floor units)

    -Zonal Pressure Balance Tests -Exhaust Ventilation Rate Verification Tests -HVAC supply and return static pressure tests -HERS modeling, documentation and submittal of final ratings.
