Presentation Notes
Vancouver has adopted aggressive targets and has dedicated staff and financial resources toward meeting our 2012 community targets. Despite increasing population, jobs and economic activity in the City, emissions have been declining since the Community Climate Protection Plan was adopted in 2005. The main reasons for these declines are the landfill gas recovery project combined with a reductions in natural gas consumption in buildings and light duty gasoline fuel sales. The gasoline sales reductions are attributed to Vancouver’s compact, mixed used development planning, its focus on providing priority for walking, cycling and transit infrastructure, as well as improvements to vehicle efficiencies.

Green Transportation

Compact mixed-use communities withEasy access to work, shopping & recreation

11

Land Use and Transportation

Clean Vehicles • Requiring electric vehicle (EV)

charging infrastructure for 20% of parking stalls in multi-family homes

• Launching public parking charging program to support EV owners

• Forming agreements with leading automakers to deploy their EVs sooner in this region

• Working closely with BC Hydro and BC Gov’t to accelerate actions

Presenter
Presentation Notes
Vancouver is becoming ever less reliant on the private automobile. In the past decade, overall, trips have increased by 23%, yet car trips in to Vancouver have declined by 10%. Even to our Downtown, the economic centre of the region, car trips are down by 7%. We are also about to embark on a cycling trial for the Burrard Bridge, which reallocates one lane of traffic for cycling, we’ve just doubled our funding for cycling infrastructure in the City and we are exploring a demonstration public bike share system for the Metro Core.

Green Building- Push & Pull

EcoDensity and Green Rezoning• LEEDTM gold for all rezonings• Green roofs for rezonings• For rezonings on sites greater than 2

acres:– District Energy Feasibility Study – Stormwater Management Plan – Low-carbon TDM Strategy

• Priority permitting for ultra-green developments

• New housing types including laneway houses and suites within apartments

Presenter
Presentation Notes
EcoDensity is an initiative to plan our communities in a way that makes them greener, more liveable and more affordable. We’ve made “green” performance a new baseline for rezonings, including requirements for energy, stormwater and transportation demand management (TDM). We’re also developing a program for expedited permitting for ultra-green developments and assessing opportunities for expanding district energy systems on redevelopment sites that are greater than 2 acres Work is also underway to bring forward new options for laneway housing, for secondary suites in apartments and for new housing types for single-family neighbourhoods.

Green Buildings

Retrofitting Existing Buildings

• Moving toward requiring energy performance for retrofit permits

• Work with utilities to develop new financing tools for energy retrofits and renewable energy technologies (e.g. on-bill financing)

• With financing tools, City can regulate improvements more aggressively

Presenter
Presentation Notes
THIS IS ONE OF TWO KEY SLIDES/CONCEPTS TO SHARE WITH TERASEN The key for Vancouver to achieve these new and existing building energy and GHG reduction targets without crippling the development and real estate industries will be the development of new tools for financing building energy improvements. Even with today’s energy prices and technologies, a 20% reduction in existing building energy use can be achieved in a financially sustainable fashion. The challenge will be to connect the benefits of improved energy performance (in terms of energy cost savings or new revenues for renewable energy) to investors with patient capital instead of burdening building developers or owners who have much shorter investment time horizons. While Vancouver is starting to explore mechanisms whereby third party investors could recover their investment in building energy projects through an incremental property tax charge, there are additional financing mechanisms that will be required. The City wants to work with innovative utilities that are interested in long term investments in financially sound building energy initiatives. We envision a distributed utility that rents roof space from building owners to install solar hot water systems and recovers its capital investment through the sale of hot water to that or even adjacent customers. We envision a model where utilities finance the incremental costs of defined and proven energy efficiency improvements for existing buildings such as condominiums and recover this investment through their utility billing. Once financing tools are established and proven for specified energy initiatives, the City can move towards requiring these improvements within the building code ensuring a significant market opportunity for participating utilities. The City is actively seeking to establish a market for these approaches. Developers seeking rezoning of large land parcels must undertake a renewable energy study to determine if and what energy supply options would be economically viable using a life-cycle assessment. As there opportunities become more evident, the City will seek utilities to fulfill this market niche.

Green Buildings

Green Homes Program (for one and two family dwellings)“The best code on the continent”

• R-20 Insulation in walls• In-suite energy use displays• Energy Star Windows• Insulated hot water tanks and pipes• 40% non-incandescent light fixtures• Direct vent gas fireplaces• Heat Recovery Ventilation• Mandatory Energuide audit• Pre-piping for renewable energy• Dual flush toilets• Electric vehicle Charging

Presenter
Presentation Notes
The Green Homes program is a series of prescriptive requirements that we designed to add no more than 2% to the construction costs of building a new home Most of the requirements have real paybacks to the owners Its competitive with the most progressive European building codes

Energy Management

• Use only the energy that you need

• Using the same principles as financial management to track energy use

• Once energy use audited, recommend upgrades– Major Equipment Upgrade

– Minor Equipment Upgrade

– Automation System changes

– Behaviour changes

21

Spending to Save

• Paying for investments with Energy Savings

• Payback (PB) is

• GHG impact less relevant when speaking in $

• City of Vancouver’s long-term vision allows for deeper investments:– Private Sector – 3-5 year payback

– Public sector ~ 10 year payback

– City of Vancouver is 20 years

Presenter
Presentation Notes
In 2004 energy performance contracting was identified as most expeditious means of acheiving desired GHG reductions The capital investment was self-funded, with the annual savings repaying the loans over 20 years.

Building that generates as much energy as it consumes

• LEED Platinum Community Centre• Green roofs (50% coverage)• Solar hot water systems• Rainwater capture and reuse• Low parking and car-sharing• Neighbourhood Energy Utility based on sewer

heat recovery, the first of its kind in North America

Presenter
Presentation Notes
In pursuing our own aggressive GHG targets, the City is demonstrating leadership in the Southeast False Creek neighbourhood. We are using projects in the Olympic Village such as the Net Zero social housing building, the LEED Platinum Community Centre, green roofs, solar hot water systems, rainwater capture and reuse systems and district energy using sewer heat recovery to catalyze local experience and capacity around green technologies. This community has provided unique opportunities for our local development and green building industry to explore and test new concepts that push the boundaries of green design.

District Energy in South East False Creek

Neighbourhood Energy Utility

• Heat distributed via network of hot water pipes to in- building heat exchangers

• Sewer Heat Recovery- 70% of Energy from Sewage

• Supplementary: Solar Thermal

• Peaking & Back-up: Conventional Gas Boilers

• Over 65% less GHG

Presenter
Presentation Notes
The SEFC NEU began providing heat to the Olympic Village this fall using temporary boilers and we are just in the process of operational commissioning of the Energy Centre heat pumps and back-up boilers. Our work on the NEU has revealed the importance of load density and timing as well as the importance of appropriate sizing and phasing of infrastructure investments. In SEFC, the sewer waste heat pumps are only sized to provide baseload heat demands – conventional boilers were an ideal solution to meet peak demands and to provide for back-up. Due to the tight timelines, the City built and is initially owning and operating the NEU. That said, the City believes there will be a role for private utilities as we move forward with renewable district energy.
