3 VANCOUVER: GREENEST CITY IN THE WORLD BY

4 GREENEST CITY FRAMEWORK 3 HIGH-LEVEL OBJECTIVES 10 GOAL AREAS 4

5 CLIMATE LEADERSHIP Eliminate Vancouver s dependence on fossil fuels World Wildlife Fund 2013 Global Earth Hour Capital for climate protection leadership FCM 2014 Green Champion Award for climate leadership Reduce community-based greenhouse gas emissions 33% from 2007 levels -6% (2013) 5

6 below 2007 levels VANCOUVER S EMISSIONS CONTINUE TO DECREASE: Since 1990 population has increased 32% and number of jobs is up 28%

7 Projected: 7

8 CONTEXT Mild climate comparable to London (with more rain) Low energy prices natural gas = $8.80/GJ electricity = $0.075/kWh Abundant and secure local energy supply Clean power 95% hydro electricity WEAK EXTERNAL DRIVERS TO BUILD EFFICIENTLY GREEN BUILDINGS 8

9 GREEN BUILDINGS Lead the world in green building design and construction Require all buildings constructed from 2020 to be carbon neutral in operations Reduce energy use and greenhouse gas emissions in existing buildings by 20% below 2007 levels -3% (2013) 9

10 CARBON NEUTRAL NEW CONSTRUCTION BY 2020 Vancouver: World Green Building Council 2013 Best Green Building Policy 10

11 Path to Carbon Neutral Construction LEAN CLEAN Reducing energy use and carbon in new buildings 1. Use stepwise improvements to building code to reduce energy demands of building envelopes and equipment 2. Use stepwise changes to rezoning policies to foster innovation and build capacity for meeting future code requirements Reduced Use Of Fossil Fuels GREEN 3. Accelerate the shift to low-carbon energy through the creation and expansion of neighbourhood energy systems

12 REZONING POLICIES Foster innovation and industry capacity for better than code development Require LEED Gold rating or better 22% lower energy costs than ASHRAE90.1 (2010) Landmark Tall Buildings must reduce energy use 45% below code requirement Must connect to lowcarbon district energy if available

13 46% increase in LEED developments in Vancouver since 2008.

14 14 LOW-CARBON DISTRICT ENERGY Neighbourhood heat energy production using waste heat or renewable energy to meet 75% of demand at competitive rates Large site new developments establishing low-carbon district systems for heat energy Low-carbon technology heat plant and expansion of legacy steam systems to lowcarbon technologies at hospitals and downtown in planning

15 Focus - High Density Neighbourhoods Downtown Central Broadway Cambie Corridor

16 VANCOUVER BUILDING BYLAW Regular amendments for improved energy efficiency Large commercial and residential buildings must meet ASHRAE90.1 (2010)

17 VANCOUVER BUILDING BYLAW Models indicate homes built to 2014 code emit 50% less GHG than those built to 2007 code Energy models Efficient windows (USI 1.4) and increased insulation (R-22 effective) air tightness (3.5 ACH) and testing heat-recovery ventilation Efficient heating equipment

18 EMERGING PRIORITIES Critical need for actual performance data (energy benchmarking) New emphasis on improved building envelope design and construction; passive building approaches Increased emphasis on compliance 100% renewable energy target means much greater emphasis on options by building type/location

19 REDUCE ENERGY USE IN EXISTING BUILDINGS

20 2014 Building Code Existing Buildings One and Two Family Dwellings Permit Value Requirement $5000+ EnerGuide Audit $25,000+ Air Sealing $50,000+ Attic Insulation 20

21 21 VOLUNTARY HOUSE RETROFITS Strong historic participation in gas and power utility incentive programs Developing pilot programs to leverage new technologies such as thermal imaging and intelligent thermostats Initiating heritage housing energy retrofit program

22 VOLUNTARY GREEN LANDLORD and COMMERCIAL BUILDING UPGRADES Energy assessments and data management for continuous optimization BOMA BESt Partner energy utilities to catalyze and support apartment retrofits 22

23 BUSINESS Green building and construction jobs: 4,500 Local food jobs: 6,000 Cleantech jobs: 3,200 23
