Custom energy-efficiency projects for existing buildings

​When saving energy requires a customized approach, our Commercial Custom Design Program for existing buildings can help. The program provides funding for natural gas energy-efficiency projects tailored to your specific building or facility. 

Are you eligible?*

  1. You must be a FortisBC commercial rate class natural gas customer.
  2. You must be a customer with medium to large commercial, institutional, multi-unit residential or light industrial buildings or facilities.
  3. Your project must have the potential to save a minimum 1,200 gigajoules of natural gas annually.

*You can find a complete list of requirements in the Participant’s guide.

Program rebates

​The program provides several types of funding to help you identify and then implement cost-effective natural gas energy conservation measures in your building.

Energy study funding is offered to help you have a detailed engineering analysis of your facility conducted to identify opportunities for cost-effective natural gas savings. Maximum funding is 50 per cent of the cost of the energy study, subject to  review and approval, to a maximum of $25,000.

Capital incentive funding is offered to encourage the implementation of cost-effective natural gas energy conservation measures identified in the energy study. The funding available is to offset the cost of implementing the approved energy conservation measures over equivalent yet less efficient alternatives.

Implementation bonus funding is offered to participants who successfully implement the approved energy conservation measures. Maximum funding is equivalent to the energy study funding, to a maximum of $25,000.

Benefits of participating

By participating in the program, you can benefit from:

  • a detailed energy study providing justification to replace old, inefficient systems
  • new, efficient equipment that can reduce operating costs and contribute to your bottom line 
  • increased occupant comfort
  • improved operation of existing energy systems 
  • reduced waste and greenhouse gas emissions
