NB Power’s New Home Energy Savings Program is a Performance based or a Prescriptive program encouraging builders to reduce their energy consumption by going beyond the minimums prescribed in the National Building Code.
You can aim for either path, but incentives can’t be combined between the two. Projects will get the higher amount of the two pathways.
Aiming for Energy Performance Tier 3, 4, or 5 from the 2020 National Building Code allows for flexibility in terms of the upgrades you build into your project. Other than a requirement on cold climate heat pumps (see below), you have choices about insulation amounts, construction approaches, and mechanical systems, among other things.
The focus of this option is on energy usage and what is called the building envelope. The building envelope is anywhere in the home where heat may escape. This includes the exterior walls, foundations, roof, windows, and doors.
The table below is adapted from the 2020 National Building Code. The energy modelling software used by the registered Energy Advisor will show if the house reaches the targets. The software will compare the house you plan to build to the same house built to code minimums. This code minimum house is called the Reference House.
|House volume Greater than 300 m³||Energy Performance Tier|
|Building envelope improvement (Note 1)||10% or higher||20% or higher||40% or higher|
|Overall improvement (Note 2)||20% or higher||40% or higher||70% or higher|
|House volume Less than or equal to 300 m³||Energy Performance Tier|
|Building envelope improvement (Note 1)||5% or higher||15% or higher||25% or higher|
|Overall improvement (Note 2)||10% or higher||30% or higher||60% or higher|
Note 1 – This is the percent improvement of the building envelope including the roof, walls, floors in contact with the ground, exposed floors, as well as windows, doors, and skylights. This includes the effects of air infiltration and exfiltration as well as mechanical ventilation.
Note 2 – This is the overall percent improvement of the house compared to the Reference House. Everything in Note 1 is included as well as the energy used for space heating, the energy used to heat domestic hot water, energy generated on site from renewables like solar photovoltaics, alongside many other smaller factors. Energy used for lighting, appliances and plug-in devices is excluded.
How to read the table above
1. Start by identifying the volume of your planned house in cubic meters. You can estimate this from your building plans or by talking with your builder. The Energy Advisor will tell you this number when they have completed energy modelling of your plans.
2. Once you know if your planned house is “bigger” (great than 300 cubic meters) or “smaller” (less than or equal to 300 cubic meters), you can find the two percentage targets by moving across the row to the right.
For example, if your planned house is “smaller” and you want to reach Energy Performance Tier 4, then your planned house needs to achieve:
To get a sense of what it might take to reach each tier, see this page for case studies.
The Prescriptive option is specific but still allows flexibility in building energy efficiency into your new home. You must complete at least 5 upgrades from the choices below that include enhancing the building envelope, mechanical systems, or domestic hot water systems. To ensure you choose enough upgrades, you should know that installing multiple units of the same equipment only counts as one of the five required upgrades. For example, installing 3 mini split heat pumps counts as only 1 of the five required upgrades. The maximum possible incentive through the Prescriptive option is $15,000.
These simplified tables outline specific upgrades, requirements, and incentive amounts. See the program guidelines for full details and requirements.
Note: The R values above are effective R values; this means they include the effects of non-insulating materials as well as framing. The term R value describes a material’s resistance to heat transfer; a higher R value means a thicker amount of insulation.
|Building envelope upgrades||Requirement||Incentive|
|Attic/sloped ceiling/flat roof||Effective - R60||$150|
|Above grade walls||Effective - R24||$2,250|
|Below grade walls||Effective - R22||$1,500|
|Basement floor and slab-on-grade||Effective - R20||$1,400|
|Windows/doors/skylights||ENERGY STAR||$20 or $50 per rough opening|
|Air Tightness||ACH 2.5 or lower (ACH stands for Air Changes per Hour and is a measure for how much air leaks into and out of a house.)||Up to $1500 for ACH 0.5 or lower|
|Mechanical system upgrades||Requirement||Incentive|
|Cold climate mini split heat pumps||Air source heat pumps must be found on the Canada Greener Homes Grant list of cold climate air source heat pumps||$400 per system|
|Cold climate multizone heat pump||$350 per indoor head|
|Cold climate central heat pump||$1,500 per system|
|Geothermal heat pump||ENERGY STAR||$2,000 per system|
|Wood/pellet furnace or boiler||US EPA or CSA B415.10||$500 per system|
