Thermal Performance and Section J Assessment

For larger developments and commercial buildings, compliance with Section J of the NCC (National Construction Code) is mandatory. Evergreen Energy Consultants provide comprehensive Thermal Performance Assessments and Section J Reports to ensure your project meets regulations for energy efficiency and comfort.

What is Section J Compliance?
Section J sets the minimum energy performance requirements for:

  • Class 2 – multi-residential buildings
  • Class 3 – accommodation (e.g., hotels, motels)
  • Class 5-9 – commercial buildings

 

Part J provisions we cover: 

  • J1 (Energy Efficiency Performance Requirements)
  • J2 (Energy Efficiency)
  • J3 (Elemental Provisions for a Sole Occupancy Unit of a Class 2 building or a Class 4 part of a building)
  • J4 (Building Fabric)
  • J5 (Building Sealing)
  • J6 (Air-Conditioning and Ventilation)
  • J7 (Artificial Lighting and Power)
  • J8 (Heated Water Supply and Swimming Pool and Spa Pool Plant)
  • J9 (Energy Monitoring and On-Site Distributed Energy Resources)
