One- to three-unit building or individually owned single-family, condominium, or townhome properties. Must be installed by a participating insulation and/ or air sealing Trade Ally. All improvements must follow Materials & Installation (M&I) Standards. Only one improvement per category qualifies for a rebate. Rebates cannot exceed installed cost.
ENERGY STAR® Certified Air Sealing
Pre- and post-blower door testing required.
Home Assessment Report to be provided to the homeowner.
Must be part of a larger project that includes the attic insulation improvement or the wall/framed floor insulation improvement.
Attic Insulation
At least 600 square feet of attic area must be improved.
Open cavity/attic floor with an effective insulation level of R-19 or less; improved to R-38 or greater.
Closed cavity covered floor with an insulation level of R-0; improved to cavity filled with insulation.
Air sealing installed to M&I Standards (see page 20 of the M&I Standards, bullet point numbers one and four).
Knee wall improvement area can be included to meet the 600 square feet requirement.
Foundation Insulation
At least 50% of the total foundation wall, or foundation ceiling area must be improved. Area must include connected crawlspaces.
An insulation level of R-0; improved to R-5 or greater.
Wall/Framed Floor Insulation
At least 600 square feet of exterior wall must be improved: wall cavity with an insulation level of R-0; improved to cavity filled with insulation.
At least 400 square feet of framed floor must be improved: framed floor with an insulation level of R-19 or less; improved to cavity filled with insulation.
Sill Box Insulation
At least 50% of the total sill area must be improved. Area must include connected crawlspaces.
An insulation level of R-0 improved to R-5 or greater
Duct Sealing
Not applicable to ductwork in conditioned space (e.g., basement or unvented crawlspace).
Must be non-sealed, non-insulated ductwork outside the conditioned space; improved to be sealed and insulated to a minimum level of R-8.
Verified Duct Sealing
Pre- and post-duct leakage testing required.
Not applicable to ductwork in conditioned space (e.g. basement or unvented crawlspace).
Must be non-sealed, non-insulated ductwork outside the conditioned space; improved to be sealed and insulated to a minimum level of R-8.
Multifamily Home Installation Requirements
Buildings with four or more units. Must be installed by a participating insulation and/or air sealing Trade Ally. All improvements must follow Materials & Installation (M&I) Standards. Only one improvement per category qualifies for a rebate. Rebates cannot exceed installed cost.
General Requirements
General Requirements (For non-insulation measures, see the Multifamily Catalog)
If more than one heating system type exists in the building, please provide all heating types, their efficiencies, and the approximate areas for each heating type.
For heating efficiency, provide the approximate heating efficiency and units (80% thermal efficiency, 3.0 COP, etc.).
If more than one cooling system type exists in the building, please provide all cooling types, their efficiencies, and the approximate areas for each cooling type.
For cooling efficiency, provide approximate cooling efficiency and units (10 EER, 14 SEER, etc.).
Rebate is not to exceed project cost.
Insulation and air sealing improvements must be installed by a participating Trade Ally.
Air Sealing
Air sealing must be completed at the same time as attic insulation.
Air sealing shall be performed in accordance with building science industry best practices and in compliance with local building codes.
Attic Insulation
Eligible insulation types include but are not limited to: fiberglass batts, spray foam, loose-fill cellulose, or other material provided that it meets local and state building codes.
Only attic area above living space (excludes laundry, storage, garage, etc.) can receive a rebate.
Existing attic insulation must be as specified in the measure description: ≤ R-11, between R-12 and R-19, or between R-20 and R-38 (excluding assembly section).
Existing insulation of R-19 or less must be improved to R-38 or greater.
Existing insulation of R-20 to R-38 must be improved to at least R-49. Square feet of insulation should be clearly listed and labeled with area type (attic or wall) on the invoice.
Wall Insulation
Eligible insulation types include but are not limited to: fiberglass, spray foam, cellulose, or other material provided that it meets local and state building codes.
Only exterior walls in contact with living space (excluding laundry, storage, garage, etc.) can receive a rebate.
Existing wall insulation must be R-5 or less.
Additional wall insulation must bring walls up to at least R-20 of cavity insulation.
The use of R-13 cavity insulation plus R-5 insulated sheathing is considered equivalent to a cavity insulation of R-20. Square feet of insulation should be clearly listed and labeled with area type (attic or wall) on the invoice.
