Update on the Enbridge Savings By Design Program

  1. 1. Savings By Design Approach and Results 1
  2. 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. 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. 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 4
  5. 5. Part 9 Residential – 2013 Results 5 Builder Reference Baseline SBD Design Model % Below Code for SBD Model 1 140.5 GJ/yr 103.6 GJ/yr 73.7 GJ/yr 47.50% 2 168.4 GJ/yr 166.7 GJ/yr 122.5 GJ/yr 27.60% 3 96.2 GJ/yr 94.8 GJ/yr 69.3 GJ/yr 27.90% 4 0.69 GJ/m2 0.53 GJ/m2 0.25 GJ/m2 64.2% 6 121.2 GJ/yr 102.7 GJ/yr 90.2 Gj/yr 25.60% 7 200.3 GJ/yr 213.5 GJ/yr 148.7 GJ/yr 25.80% 8 118.0 GJ/yr 107.3 Gjyr 85.3 GJ/yr 27.70% 9 126.7 GJ/yr 102.4 GJ/yr 83.0 GJ/yr 34.5% 10 99.1 GJ/yr 96.7 GJ/yr 73.9 GJ/yr 25.4% 11 85.9 GJ/yr 83.2 GJ/yr 61.2 GJ/yr 28.7% 12 150 GJ/yr 113.4 GJ/yr 56.5 GJ/yr 62.4% Average 36.1%
  6. 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. 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 7
  8. 8. Part 3 Commercial/Institutional - Results 8 Builder Reference Baseline SBD Design Model % Below Code for SBD Model 1 1,843,469 ekWh/yr 1,802,870 ekWh/yr 1,344,948 ekWh/yr 20.7% 2 0.544 GJ/m2 0.329 GJ/m2 0.271 GJ/m2 50.2% 3 2,600,845 ekWh/yr 2,108,629 ekWh/yr 1,812,284 ekWh/yr 30.3% 4 0.399 GJ/m2 0.330 GJ/m2 0.261 GJ/m2 34.5% 5 1,614,723 ekWh/yr 1,617,300 ekWh/yr 1,074,300 ekWh/yr 33.5% 6 TBD TBD TBD TBD 7 2076 GJ/yr 937 GJ/yr 55% 8 796,2000 ekWh/yr 404200 ekWh/yr 49% 9 5020136 ekWh/yr 3416868 ekWh/yr 32% Average 38%
  9. 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 – Contact SBC or Enbridge 9
