5 Pathways for deep emissions reductions in buildings Context for low-carbon district energy systems Tom-Pierre CEA webinar, 23 February 2017

6 Leading Canada s transition to a clean energy future The Pembina Institute advocates for strong, effective policies to support Canada s clean energy

7 Context Carbon reduction targets for building sector The role of energy efficiency and fuel switching Tensions between building code evolution and district energy

8 Annual emissions in Mt CO2e B.C. Emissions % BC 2020 target 20-80% 10 BC 2050 target CIMS modeling by Navius

9 Annual emissions in Mt CO2e B.C. Emissions % BC 2020 target -30% from 2005, based on federal target 20-80% 10 BC 2050 target CIMS modeling by Navius

10 Annual emissions in Mt CO2e B.C. Emissions % BC 2020 target -30% from 2005, based on federal target Reference case 20-80% 10 BC 2050 target CIMS modeling by Navius

11 Annual emissions in Mt CO2e B.C. Emissions % BC 2020 target -30% from 2005, based on federal target Reference case CLP + Fed. Carbon price 20-80% 10 BC 2050 target CIMS modeling by Navius (+ forestry credits)

12 Reduction target for building sector?

13 Reduction target for building sector? Env. & Climate Change Canada overall: -80% (below 2005) Stationary sources -87% Trottier, current technology scenario overall: -65% (below 2015) residential - 87% commercial - 76% Trottier, new technology scenario overall: -65% (below 2015) residential -89% commercial -88% Deep decarbonization pathways overall: -89% (below 2015) residential -99% commercial -99% Buildings: -80% to 100% By 2050 i.e. near total decarbonization

14 Proposed building sector targets 40-50% by % by 2050

15 Net Zero Ready Commitments Ontario Code to require Net Zero Carbon for small buildings by 2030 B.C. Code to require Net Zero Energy Ready by 2032 Feds Net Zero Ready code released in 2020 for broad adoption by 2030

16 What about existing buildings?

17 Buildings emissions (Mt) Buildings emissions Base case NZEr building code Shallow retrofits Low carbon pathway

18 Low carbon pathway Efficiency Deep retrofit of 3% of stock / yr (60% reduction) Hybrid Moderate retrofit of 3% of stock / yr (25% reduction) + Fuel switch 1 out of 2 Fuel switching Fuel switching 2% of stock / yr to low carbon fuel

25 Post-audits per month % of eligible stock retrofitted How does that compare? 4,000 Average energy reduction: ~ 25% 7% 3,500 6% 3,000 2,500 2,000 1,500 1, ecoenergy v.i / LSBC v.i ecoenergy v.i LSBC v.ii LSBC v.iii / ecoenergy v.ii LSBC v.iii LSBC v.iv HERO Bonus v.i & ERS 5% 4% 3% 2% 1% 0 0% Data: Gov. of B.C.

26 Tensions between DE and efficiency What is the future of district energy systems if netzero buildings become an increasing share of the building stock? Should developers be allowed to reduce efficiency if the heat supply is from a low-carbon source? Could DE business cases still work if only delivering domestic hot water? Still worth pipes in the ground?

39 Modelling is showing that future Large Scale GHG emission reductions in Toronto may primarily come from two sets of strategies: 1. District Energy w/ Large Renewables + Efficient Buildings 2. Transit + EVs For Cities to achieve a low-carbon future District Energy is to buildings, what Transit is to transportation Environment and Energy Division

46 Discussion What is your local government looking at when in comes to reducing carbon in buildings and what is the role of DE?

47 Proposal to Establish a Canadian District Energy Working Group The goal is to advance the next generation of district energy in Canada: positioning the DE industry for a changing energy system and low carbon economy A diverse set of organizations will be invited to form the DE working group, starting with interested IDEA Canadian Forum members and QUEST subscribers Objectives are to: 1) Advocate for supportive policies and programs 2) Enhance awareness and education Among policymakers at the federal, provincial and municipal levels and with building developers and operators February 23 rd, 2017
