The Challenge

� US – nearly half of emissions

� Canada – around 1/4 of emissions

� Growing faster than any other sector

Building sector emissions

10

� Over 900 billion ft2, 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 2050.

Setting the vision

12

The good news – we are positioned well

13

Proposed building sector targets

40-50% by 2030

80-100% by 2050

14

How do we get there?

� Retrofits at scale

� Electrification, and…

� Resilient, zero emissions-ready new construction

Enabling Policies

Vancouver

� Previously removed barriers to Passive House construction

� Now, Passive House certification will be required for all new city owned buildings

34

Vancouver’s Zero Emissions Building Plan

2016: 50-64% GHG reduction2020: passive house performance* (for rezoning)2025: zero carbon

2016: 60% GHG reduction 2020: near passive house performance2025: zero carbon

2014: 50% reduction in GHG intensity2020: 70% reduction in GHG intensity2025: zero carbon, thermal load <30 kWh/m2/yr

(9.5 KBTU/sf)

* i.e. Thermal load intensity < 15 kWh/m2 (4.7 KBTU/sf)

Collaborative Design

Pan-Canadian Framework on Clean Growth and Climate Change

� Net-zero energy ready model building code by 2030

� Retrofit model code by 2022

� Mandatory energy labelling by 2019

� Improvements to equipment and appliance standards

Barriers and Solutions

What is needed?

40

� 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

Common barriers

41

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

Early Strategic Actions

1. Buildings on the ground

42

2. Liberate energy information

3. Free up capital

4. Training, education, sharing

5. Prepare the market for future regulation

Q: Which strategic actions can we influence?

� A: All of them!

� Direct influence at the micro level +

� Advocacy at the macro level

43

Strategic Actions:Top-down and bottom-up

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

More Passive Houses, and more diversity

2. Ensure markets and decision makers have access to energy information� Benchmarking, reporting and disclosure

� Universal home energy labelling

3. Free up additional capital to cover incremental cost� Repayment mechanisms:

� PACE � On-bill financing� Energy service agreements

� Credit enhancements� Loan loss reserves� Loan guarantees� Interest rate buy-downs

� Infrastructure banks
