8 Building sector emissions US nearly half of emissions Canada around 1/4 of emissions Growing faster than any other sector 10

9 Urban renewal Over 900 billion ft 2, will be built and rebuilt in urban areas by 2030, an area roughly equal to 60% of the current global building stock. If construction standards do not evolve rapidly, inefficiencies will be locked in and could lead emissions from the building sector to double by

38 What is needed? The technologies, products and practices already exist Moving to the norm still requires a shift in industry practice The pace required calls for public and private mobilization 40

39 Common barriers 1.Political vision and regulation 2. Industry capacity 3. Business case and financing 4. Supply chain 5. Public and industry awareness of passive design and benefits 6. Quality assurance Photo: Roberta Franchuk, Pembina Institute 41

40 Early Strategic Actions 1. Buildings on the ground 2. Liberate energy information 3. Free up capital 4. Training, education, sharing 5. Prepare the market for future regulation 42

41 Q: Which strategic actions can we influence? A: All of them! Direct influence at the micro level + Advocacy at the macro level 43

42 Strategic Actions: Top-down and bottom-up

43 1. Get more passive buildings on the ground Public procurement policy Rezoning incentives and removal of barriers Incentive for low-cost, high-performance exemplary buildings 45 Photos: Passive House Canada
