Home Energy Assessment Eligibility Criteria

Home Eligibility

We can help with rebates and/or financing if your home meets the following conditions:

  1. Is located in Nova Scotia
  2. Is at least 6 months old from the date on the occupancy permit
  3. Is at least one of the following categories:
    1. Single-family homes
    2. Semi-detached homes (i.e. duplex)
    3. Side-by-side row homes (i.e. townhouse)
    4. Year-round cottages
    5. Mobile homes on a permanent foundation
  4. Has all interior and exterior finishes in place (including, for example, siding and drywall) and has a functioning automated heating system.


Product Eligibility

  • Upgrades must be purchased and installed after the date of the initial assessment.
  • Participation in the Home Energy Assessment program precludes homeowners from receiving rebates for the same upgrades in other Efficiency Nova Scotia programs (such as Heating System Rebates). Only rebates from one program will be issued for any upgrade.



  • Rebates or financing are only available when you insulate at least 20% of that component. For example, if you only upgrade 18% of your basement foundation wall area, no rebate will be paid.
  • Rebates are pro-rated based on the percentage of the building component area insulated. For example, if you only upgrade 50% of your attic, you will receive 50% of the rebate.
  • When the roof consists of more than one type (i.e. attic, cathedral ceiling, and/or flat roof), ceiling rebates are pro-rated based on the overall ceiling area and roof type. For example, insulating two ceiling types does not result in obtaining the maximum rebate for each ceiling type.
  • For a semi-detached or end unit row house, foundation and exterior wall rebates are 75% of the amounts shown. For a middle unit row house, rebates are 50% of the amounts shown.
  • Foundation rebates are pro-rated based on the overall percentage of basement wall area insulated. When both a basement and crawlspace are insulated, rebate amounts are combined to a maximum of $1,200.

Heating, Hot Water, and Solar Equipment

Ductless Mini-split Heat Pumps

  • Must be on the Efficiency Nova Scotia Cold Climate Heat Pump product list: efficiencyns.ca/minisplits.

  • Single zone system Heating Seasonal Performance Factor (HSPF) for Region 4 ≥ 11.00 (Equivalent to region 5 HSPF ≥ 9.565)
  • Multi zone system HSPF for Region 4 ≥ 10.0 (Equivalent to region 5 HSPF ≥ 8.696)
  • ENERGY STAR (version 5.0) qualified
  • The Coefficient of Performance (COP) at maximum capacity operation for -15°C outdoor temperature & 21°C indoor temperature must be ≥ 1.75


Centrally Ducted Heat Pump

  • Only ENERGY STAR (Version 5.0) qualified heat pumps are eligible.


Air-to-Water Heat Pumps

  • All air-to-water heat pumps must be third-party tested to CSAC656-05 or ANSI/AHRI 210/240-1994 (EER) or equivalent.
  • Air-to-water systems must meet the following efficiency requirements:
  • Split System
    · SEER greater or equal to 15.0
    · EER greater or equal to 12.5
    · HSPF Region 4 (US) greater or equal to 8.5
    · HSPF Region 5 (Canada) greater or equal to 7.4
  • Single Package
    · SEER greater or equal to 15.0
    · EER greater or equal to 12.0
    · HSPF Region 4 (US) greater or equal to 8.2
    · HSPF Region 5 (Canada) greater or equal to 7.1

Ground Source Heat Pumps

  • The system must be installed and certified by a Canadian Geoexchange Coalition (CGC) qualified installer.


Wood and Pellet Stoves and Furnaces

  • Eligible wood/pellet equipment must meet either the CSA-B415.1-10 or the US EPA 40CFR Part 60 AAA standard. All wood/pellet stoves must be EPA or CSA certified with emissions rating of ≤ 4.5 g/hr for total filterable particulate matter(TPM). All wood/pellet furnaces or boilers must be EPA or CSA certified with emissions rating of ≤ 4.5 g/hr or ≤ 0.40g/MJ for TPM. For a list of potential equipment, visit EPA’s website.
  • All wood/pellet systems must be installed by a Wood Energy Technology Transfer (WETT) certified professional that has either “Technician” or “Sweep” certification. Alternatively, an installation can occur by a non-WETT certified installer, however the entire system must be subsequently inspected and approved by a WETT certified inspector.
  • Outdoor wood/pellet furnaces or boilers are not eligible for rebates or financing.

Hybrid Heat Pump Water Heaters

  • The hybrid heat pump water heater must be ENERGY STAR certified.
  • The equipment must be in a room at least 1,000 ft3 in volume (roughly 12ft x 12ft).


Solar Systems

  • All solar collectors (both Air and Domestic Hot Water) must be certified under one of the following CSA classes:
    • CSA Class 2831-06, 2831-07, 2831-30 or 2831-37
    • CSA Class 8854 (Previously CSA F378/F379)
  • Qualified Solar Domestic Hot Water Systems can be found at Natural Resources Canada’s website – Performance Directory of Solar Domestic Hot Water Systems.
  • The Solar Domestic Hot Water System is designed for year-round operation for domestic water use (although other applications may be incorporated into system design e.g. space heat).
  • The equipment is installed according to industry best practice and manufacturer’s instructions.
  • A minimum of R-3 pipe insulation is installed on:
    • The first 3 metres (10 feet) of the cold and the full length of hot water piping (if accessible) connected to the
      conventional water heater.
    • All piping connecting the solar storage tank to the solar collector.
    • All piping connecting the solar storage tank to the conventional water heater.


Air Sealing

  • Achieve the air sealing target identified in your renovation upgrade report to be eligible for the rebate.


Windows, Doors & Skylights

  • Please note that windows, doors & skylights are not eligible for low interest financing. In the event that you decide to finance other upgrades and still install eligible windows, doors or skylights, they will be eligible for rebates.
  • Windows, doors, and skylights that are ENERGY STAR qualified for climate zone 2 (previously climate zone B), and which are installed into pre-existing rough openings are eligible for rebates.
  • Each qualified model comes with a temporary label/sticker showing the appropriate ENERGY STAR climate zones. Keep these stickers on the windows/doors until your final Home Energy Assessment is complete.
  • Rebate amounts are calculated per rough opening, not per number of windows. For example, a bay window with three window units installed into one rough opening is eligible for only one rebate.
  • Inserting an ENERGY STAR qualified window unit into the existing frame of an old window qualifies for rebates, however, replacing the glass, sash, or door without a frame is not eligible for rebates.


Basement Header Insulation

  • Add ≥R-20 to 100% of basement headers.


Exposed Floor Insulation

  • Add ≥R-20 to at least 150 square feet of exposed floor area (e.g. floor over an unheated garage).


Basement Slab Insulation

  • Add at least R-3.8 of insulation to 100% of the basement slab.


Drain Water Heat Recovery

  • The equipment must have a heat recovery efficiency of greater than or equal to 42% as determined by an independent testing facility.
  • Qualified drain water heat recovery systems can be found at Natural Resources Canada’s website.


Heat Recovery Ventilation

  • Certified by the Home Ventilating Institute (HVI) as a heat-recovery ventilator (HRV) or energy-recovery ventilator.
  • If replacing pre-existing air exchanger, the HVI certified HRV must replace a non-HVI certified HRV.
