Saskatchewan Energy Code Compliance for Residential Construction
The Saskatchewan Energy Code for residential construction is embedded within the Saskatchewan Building Code (SBC), which adopts the National Building Code of Canada (NBC) 2020 with province-specific amendments. Effective January 1, 2023, Saskatchewan mandates compliance with NBC 2020 Part 9 (Housing and Small Buildings) and Part 11 (Energy Efficiency), as modified by the Saskatchewan Regulations under The Uniform Building and Accessibility Standards Act. These requirements apply to all new single-family homes, duplexes, townhouses, and low-rise residential buildings (≤3 storeys). Compliance ensures reduced energy consumption, improved occupant comfort, and alignment with provincial climate action goals—including Saskatchewan’s Net-Zero Emissions Target by 2050.
Overview
The Saskatchewan Energy Code for residential construction is embedded within the Saskatchewan Building Code (SBC), which adopts the National Building Code of Canada (NBC) 2020 with province-specific amendments. Effective January 1, 2023, Saskatchewan mandates compliance with NBC 2020 Part 9 (Housing and Small Buildings) and Part 11 (Energy Efficiency), as modified by the Saskatchewan Regulations under The Uniform Building and Accessibility Standards Act. These requirements apply to all new single-family homes, duplexes, townhouses, and low-rise residential buildings (≤3 storeys). Compliance ensures reduced energy consumption, improved occupant comfort, and alignment with provincial climate action goals—including Saskatchewan’s Net-Zero Emissions Target by 2050.
Key Requirements
Residential projects must meet minimum thermal performance standards: walls (R-22.5), above-grade floors (R-27), ceilings (R-50), and basement walls (R-17.5). Air leakage must not exceed 1.8 ACH@50 Pa (air changes per hour at 50 pascals), verified via blower door testing. Mechanical ventilation systems must be installed in all dwellings and sized per CSA F326, with heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs) required where applicable. Electrical installations must comply with CSA C22.1:23 (Canadian Electrical Code, Part I), including dedicated circuits for energy-efficient appliances and proper grounding. Lighting must be ≥90% LED or equivalent efficacy; recessed luminaires in insulated ceilings require IC-rated, airtight housings. All insulation must be installed without gaps, compression, or thermal bridging, and ductwork must be sealed and insulated to R-6 in unconditioned spaces.
Step-by-Step Process
1. **Design Phase**: Engage a licensed designer or energy advisor to perform preliminary energy modeling using approved software (e.g., HOT2000 v10.4+ or E-Quest). Confirm compliance with SBC Table 9.36.2.1. and Part 11 prescriptive or performance paths. 2. **Permit Application**: Submit plans—including insulation details, air barrier drawings, mechanical system specs, and electrical schematics—to the local municipal authority or Saskatchewan’s Office of the Fire Commissioner (for rural areas). Include completed NRCan EnerGuide Rating System forms if pursuing performance compliance. 3. **Construction & Inspections**: Schedule mandatory inspections: rough-in (framing/insulation/air barrier), mechanical/electrical rough-in, and final (blower door test + ventilation commissioning report). Third-party verification by a NRCan-licensed energy advisor is required for EnerGuide labeling. 4. **Certification**: Upon passing all inspections and tests, obtain the Certificate of Compliance from the authority having jurisdiction (AHJ) and register the home in the EnerGuide database.
Costs
Compliance typically adds 2–5% to baseline construction costs. Key cost drivers include high-R-value insulation (e.g., spray foam or dense-packed cellulose), HRV/ERV units ($1,800–$3,200 installed), airtight drywall/advanced sealing systems ($800–$2,000), and energy modeling/verification services ($600–$1,500). Rebates are available through SaskPower’s Residential New Construction Program (up to $2,500) and federal Canada Greener Homes Grant (up to $5,000), partially offsetting these expenses.
Common Mistakes
Failing the blower door test due to unsealed penetrations (e.g., plumbing stacks, electrical boxes, rim joists); installing insulation with gaps or compression—especially around windows and headers; omitting continuous air barriers on all six sides of the envelope; undersizing or improperly balancing HRV/ERV systems; and submitting incomplete electrical documentation that omits CSA C22.1 grounding and arc-fault protection requirements for bedrooms and living areas.

Is a blower door test mandatory for all new homes in Saskatchewan?
Yes. Per SBC 2020 Part 11 and Saskatchewan Regulation 112/2022, every new residential building must undergo an on-site blower door test conducted by a NRCan-licensed energy advisor prior to occupancy. Results must be documented and submitted to the AHJ.
Can I use the prescriptive path instead of energy modeling?
Yes—the prescriptive path (SBC Table 9.36.2.1.) is permitted for standard designs meeting all listed R-values, air leakage limits, and equipment efficiencies. However, complex geometries, high-performance goals, or custom assemblies often require the performance path with modeling.
Who is authorized to sign off on electrical compliance?
Only licensed electrical contractors registered with the Saskatchewan Apprenticeship and Trade Certification Authority (SATCA) and certified under The Electrical Inspection Act may install and certify electrical systems. Final sign-off requires inspection by a provincial Electrical Safety Authority (ESA) officer.
