Mike Singleton of Sustainable Buildings Canada presented an overview on the results of the first year of Enbridge Savings By Design builder workshops. Savings by design aims to help Ontario builders of commercial buildings and production residential projects surpass the energy requirements of the Ontario Building Code by 25%.

1. Savings By Design
Approach and Results
1

2. Savings By Design Program
– Developed by Enbridge Gas Distribution in
2012 – approved by the OEB for 2012-2014
– A “market transformation” program for Part 3
and Part 9 (production) builders and their
design teams
– Includes incentives and support for design
activities and building energy performance
– Delivered by SBC – 2nd year of the program
2

3. Part 9 Residential
– Part 9 Residential program focuses on larger
production builders who build at least 50 homes per
year
– Provides funding for design workshop (“Charrette)
including modelling and input from 3rd party building
science and technology experts
– Design Charrette outcome must demonstrate >25%
better than OBC to be eligible for follow on
incentives
3

4. Part 9 Residential
– Follow-on energy performance incentive of
$2000 per home (max 50 homes)
– Relies on the EnerQuality process to affirm that
homes are built to 25% better than Code
– Can be stacked with OPA incentives
– So far, 1 builder has received a $100 K
incentive

6. Part 3 Commercial/Institutional
– Part 3 Commercial program focuses on
commercial (including MURBs) > 100,000 sq. ft.
– Provides funding for design workshop
(“Charrette) including modelling and input from
3rd party building science and technology
experts
– Design Charrette outcome must demonstrate
>25% better than OBC to be eligible for follow
on incentives
6

7. Part 3 Commercial/Institutional
– Follow-on energy performance incentive of
$.20/m3 of modelled energy savings (up to
$50,000) and a commissioning incentive of up
to $5000
– Uses e-Quest (or similar) energy modelling as
the basis for savings
– Can be stacked with HPNC

9. Savings By Design Program - Summary
– Achieving the 25% threshold is achievable
– Need to consider alternatives at the design
stage
– No significant impact on cost
– Represents an opportunity to lead the industry
and capitalize on available incentives
