(For properties with electric cooling)

  • All required documentation must be postmarked within 90 days of completion of the qualifying product or service purchase
  • Work must be completed by a Qualified Contractor
  • Incentives are available for existing multifamily properties only and may be installed by a qualified contractor or self-installed by property owners or landlords
  • Duct sealing and duct insulation services can be performed by multiple trade allies and must be performed at the same time to qualify
  • Ducts must be located in an unconditioned space. Definition of unconditioned space: an unconditioned space is any space outside of the thermal envelope of the building that is not intentionally heated for occupancy
  • Must have a minimum of 10 linear feet of exposed ductwork located in an unconditioned living space
  • Property must have an electric heating system serving at least 80 percent of the home’s conditioned living space
  • Duct sealing must reduce duct leakage to outside by 50 percent with a 100 CFM minimum reduction
  • Duct insulation must be installed after ducts are sealed
  • Ductwork must be insulated to a minimum of R-8 or replaced all existing insulation to a minimum of R-8
  • Pre-existing insulation must be non-existent or less than R-2

Conditioned vs. unconditioned space - clarification notes

  • For the most part, basements are conditioned spaces. Basements are not usually thermally isolated from the main living area and contain space conditioning ducts. Basements are also used for storage and frequently contain laundry facilities and other living spaces. Ducts serving unfinished basements are not always equipped with dedicated supply registers, although single registers at plenums are not unusual.
  • An unconditioned basement would have these properties: Thermally isolated from the main floor by insulation in the floor. Insulated, weather-stripped door (if above floor plane) and insulated stairwell walls where thermal plane penetrates floor, air sealed (caulked, foamed penetrations) wiring plumbing, sealed duct penetrations and sealed, insulated ducts. No supply registers.
  • While a crawlspace is unconditioned space, the floor must be insulated prior to or at the same time ducts are sealed and insulated to thermally isolate the crawlspace. Failure to do this will increase the heating load of the home and potentially cause comfort issues.

      • Specific street address or account number
      • Complex name
      • Contact at the complex and phone number where they can be reached
      • Measures that are being requested to be inspected​
    • Once this information is received, an inspector will assess the complex to verify whether it qualifies and if it would benefit from our incentive offerings.
    • Your contractor will be notified of the status of the inspection. If the complex qualifies for any of the Home Energy Savings program incentives, the contractor will schedule a time with the property manager to complete the work.

Contractor completes energy upgrades:

  • The contractor will perform the necessary work for the project to qualify for an incentive. Consult with your contactor to get a clear understanding of the work being performed and how long it will take. Also remember to notify your tenants about the work being done.

Application is submitted:

  • Once the work is completed, the contractor submits one incentive application for the entire multifamily property to the Home Energy Savings program.
  • All units listed on the application must be verified on the landlord account (units may need to be added if they are not under the landlord account at time of review).
  • One itemized invoice detailing the work performed for the property must be submitted.
  • A completed W-9 form for the person or entity receiving the incentive check must be submitted along with the application for tax purposes. For changes to account name, contact Business Solutions at 1-866-870-3419.

  • Applications cannot be processed if any required documentation is missing.
  • The property is then queued for a post-work inspection.

Post-work inspection:

  • After receipt of a completed incentive application the program will schedule a post-work inspection to verify all program requirements have been met.
  • A minimum of 25 percent of the units that received an energy efficiency upgrade must be inspected
  • Tenants should be notified of this post-work inspection beforehand.
