Proposed Change 2044
Code Reference(s):
NBC25 Div.B 9.36.12. (first printing)
Subject:
Energy Efficiency for Houses
Title:
Energy Performance Tier 3 of the Prescriptive Path
Description:
This proposed change provides energy-efficiency requirements for compliance with Tier 3 of the energy performance compliance prescriptive path.
Problem
The 2020 edition of the National Building Code of Canada (NBC) introduced energy efficiency performance tiers in Section 9.36. of Division B, with increasing levels of improvement for buildings and houses, to provide authorities having jurisdiction with the option to adopt the energy performance levels most suitable to their needs.
Although performance modeling is common in the industry, many Code users have requested that prescriptive compliance paths remain in the National Model Codes to provide simplicity in achieving energy compliance.
Failure to develop a prescriptive compliance path for Tier 3 could force Code users to rely on more complicated compliance paths.
Justification
The proposed prescriptive requirements for Tier 3 would provide acceptable solutions for different components of the building to improve the total energy performance. Together with the tiered energy performance path in Subsection 9.36.7. and the tiered points-based prescriptive trade-off path in Subsection 9.36.9., the prescriptive path is one of the compliance options that provide an acceptable means of achieving the performance goal of reducing energy consumption by at least 20% and percent heat loss by at least 10% for buildings with a volume of conditioned space (or “conditioned volume”) greater than 300 m3, and by reducing energy consumption by at least 10% and percent heat loss by at least 5% for buildings with a conditioned volume less than or equal to 300 m3.
In developing the Tier 3 prescriptive solutions, many different possible solutions were considered. These possible solutions were compared against the points-based trade-off path to ensure compliance.
Building Envelope
A Tier 3 envelope package was developed for each climate zone. 240 building archetypes were modeled and categorized by volume, with 219 having a conditioned volume greater than 300 m3 and 21 having a volume of less than or equal to 300 m3.
For the applicable building volume and climate zone, two criteria were used to define acceptable Tier 3 building envelope package solutions:
- At least 80% of the archetypes must comply with the Tier 3 requirement for percentage heat loss reduction.
- On average, the archetypes must have a peak heating load less than their reference building.
There are numerous combinations of envelope measures that meet the above criteria. Therefore, additional selection criteria needed to be defined to reduce the number of prescriptive envelope package solutions to one for each climate and building volume.
The two additional criteria were as follows:
- Solutions should minimize incremental costs.
- Component performance of the building envelope must consistently increase across climate zones.
A fourth criterion was defined to ensure that, when going from a warmer to colder climate zone, the thermal performance of a building envelope component was not reduced. For example, a solution that uses 4.88 RSI for the effective thermal resistance of above-grade walls in climate zone 6 would not be used if the solution for climate zone 5 used 5.69 RSI for above-grade walls.
Airtightness
There is no mandatory airtightness level that must be met to achieve Tier 3.
HVAC and Service Water Heating System
Heat/energy recovery ventilators (HRVs/ERVs) are considered an economical way to save energy; it was proposed that all Tier 3 houses be equipped with HRVs/ERVs with a minimum 70% sensible recovery efficiency. As HRVs/ERVs are required for the Tier 1 and Tier 2 packages, the requirement is maintained in the Tier 3 package.
For buildings with a conditioned volume less than or equal to 300 m3, no upgrades beyond Code-minimum space heating systems are required to achieve Tier 3. For buildings with a conditioned volume greater than 300 m3, upgrades are required when heating with a gas- or oil-fired furnace.
For buildings with a conditioned volume less than or equal to 300 m3, no upgrades beyond Code-minimum service water heating systems are required to achieve Tier 3. For buildings with a conditioned volume greater than 300 m3, upgrades are required when the water heater is gas- or oil-fired.

This proposed change would improve energy performance by providing the prescriptive requirements for building envelopes, service water heating systems and HVAC systems to achieve Energy Performance Tier 3.
Buildings with a total volume of conditioned space of less than or equal to 300 m³ have the following energy performance targets: a percent improvement of ≥10%, a percent energy target of ≤90% and a percent heat loss reduction of ≥5%.
Buildings with a total volume of conditioned space of greater than 300 m³ have the following energy performance targets: a percent improvement of ≥20%, a percent energy target of ≤80% and a percent heat loss reduction of ≥10%.

Enforcement implications
This proposed change can be enforced by the infrastructure currently available to enforce the Code.
This proposed change facilitates effective enforcement of high-performance energy solutions in jurisdictions where complying with the performance path is problematic.
Who is affected
Regulators, builders, designers, engineers, architects, contractors and consultants in provinces and territories where Energy Performance Tier 3 for housing and small buildings is adopted.
