How the CF-6R works:

The CF-6R installation certificate is completed during the construction phase of the compliance and enforcement process.  The CF-6R is really several documents in one.  The documents are completed by the contractors responsible for installing the windows, the HVAC equipment and ducts, the insulation, and the lighting systems.

The CF-6R is signed by various installers.

  • HVAC systems. The contractor who installs mechanical equipment signs this part.  Heating and cooling equipment are listed and the energy efficiency, capacity, design loads and other properties of each piece of equipment is documented.
  • Water Heating Systems. This part includes information about the water heating equipment installed in the building, including model number, energy efficiency, tank size, input rating and other properties.  The installer also verifies that faucets and shower heads are certified and comply with the appliance standards.
  • Fenestration/Glazing. This part includes a list of all windows installed in the home.  For each, the U-factor, SHGC, area, number of panes, and number of windows of this type in the building are indicated.  This section is signed by the contractor that installs the windows.
  • Duct Leakage and Design Diagnostics. This part is signed by the contractor responsible for installing the HVAC duct systems and verifying that they comply with the leakage requirements.  On this form the contractor includes the results  of the diagnostics tests, which will later be verified by a third-party inspector (HERS rater)
  • Refrigerant Charge and Airflow Measurement. This part is signed by the contractor responsible for verifying that split system air conditioner and heat pumps have the correct refrigerant charge.  This form contains diagnostic data that are later verified by a third-party inspector (HERS rater)
  • Duct location and Area Reduction Diagnostics. This part is completed and signed by the contractor who installs the HVAC ducts.  It verifies the location of the ducts and/or includes information on duct location.  This form is used only when the default duct area is not assumed.
  • Building Envelope Leakage Diagnostics. This part is completed by the contractor responsible for testing building envelope leakage through pressurization of the house.  This form contains test results that will later be verified by a third-party inspector (HERS rater)
  • Insulation Certificate. This part is completed and signed by the contractor responsible for installing the insulation.  This indicates the manufacturer, brand, and thermal properties of the insulation installed in the roof, ceiling, walls and floor.
  • Insulation Quality Checklist. This part is completed and signed by the insulation contractor when credit is taken for quality insulation installation.  This is later verified by a third-party inspector (HERS rater).
  • Lighting Systems. This part is completed and signed by the contractor responsible for installing hard-wired lighting systems.

Persons signing these CF-6R forms are verifying that the installed efficiencies or requirements meet or exceed those used for compliance with the standards as shown on the CF-1R.  The CF-6R must be posted at the job site in a conspicuous location (e.g., in the garage) or kept with the building permit and made available to the enforcement agency upon request.

When field verification and/or diagnostic testing is required for a home, the builder shall provide a copy  of the CF-6R to the HERS provider/rater and to the building department upon request.

Information from the CF-6R is included with the homeowners manual.  This provides the homeowner with information about energy efficiency features installed in their home.
