Energy efficiency includes requirements affecting building envelope, heating, ventilation and air conditioning (HVAC), and service water heating.
These are intended to address:
- Air leakage
- Uncontrolled thermal transfer
- Unnecessary energy demand or consumption for heating and cooling, service water heating, and electrical equipment and devices
- Inefficiency of equipment and systems
- Unnecessary rejection of reusable waste energy
The same provincially-trained and certified Safety Codes Officers who issue building permits and inspect construction also administer the new energy codes.
The following paths are available to achieve the energy efficiency requirements:
- Prescriptive Path
- Prescriptive with Trade-Off Path
- Performance Path
- Tiered Performance Path
- Tiered Prescriptive Path
Learn more about the paths in the NBC(AE) 9.36 Energy Efficiency Requirements Guide.
