Green or Green-Wash? Lessons from building North America’s greenest hotel

Green or Green-Wash? Lessons from building North America’s greenest hotel

Speaker: Tom Rand, MaRS Advisor and Cleantech Practice Lead

Buildings are responsible for more than half of urban carbon emissions. Greening our buildings is clearly a cleantech priority - but what does "green" mean? Which technologies work, and which are window-dressing? What's possible by economic argument alone? This talk will take you through the technologies, decisions and problems of transforming a derelict building on our very own College Street into a modern, clean and green hotel. By "green" we mean an 80 per cent reduction of carbon emissions from business as usual. Planet Traveler will be "North America's Greenest Hotel." Planet Traveler: green, or green-washed?

    • LESSONS FROM BUILDING NORTH AMERICA’S GREENEST HOTEL IN TORONTO Part of the MaRS BEST PRACTICES SERIES Date: Produced by: Generously supported by: July 9, 2009 Moderator: Tom Rand Cleantech Practice Lead, MaRS
    • Carbon Reduction and Climate Change: “climate change … could alter the way we live in the most Fundamental way. … It is life itself that we battle to preserve.”, Margaret Thatcher, 1989, Address to U.N. General Assembly Cleantech = Third Industrial Revolution Global Targets: as Political Responses align with Scientific Realism … 50% - 80% reductions by 2030 – 2050. “Green”: Reduction in energy use, carbon emissions. Buildings: 50%-75% of carbon emissions in large urban centers, 40% overall. ( What about Water? - only 2.4% of Toronto’s electrical consumption is used for water treatment and delivery. )
    • Our Target: 75% reduction in carbon emissions (BAU) on an on-going basis – sustainable operations.
    • Existing Standards: LEED BOMA TRCA Pragmatism: Avoid “paralysis by analysis”: Use existing case studies as first-order feasibility study. Introducing: The “ no-CaRbon.As.by.Product.” Model Platinum: no carbon at all. Gold: Planet Traveler. Fail: Green Hotel Association. The Basic Lessons … Technologies exist, that stand on economic merits. ( If we can do this, anyone can do this. ) The problems are soft, not hard (people, process, capital)
    • Us: Existing shell, limited south exposure.
    • Partnering with the City of Toronto Opening up the Laneways and Parks Savings: 50-70% of heating/cooling
    • 20% of hot water
    • Entire building’s lighting = a two-slice toaster.
    • 10 kw system: All electrical power, except the heat pumps. Easily 10% of total power.
    • Technology Energy Reductions Geo-exchange 40 % Solar Thermal 7.5 % Solar PV 15% (up to 25%) Power-pipetm 7.5% LED Lighting/switching 5% Total: 77.5% (Up to 85%) Cost: < $200,000 = 5% of buildings value Monthly Savings: $ 2500 / 15% return / 6.5 year payback
    • Three Ways to Estimate (besides guessing …): 1. Comparable Building, Comparable Use. 2. Measure performance of equipment. eg. Ground loop, Solar Thermal, Power-pipe 3. Model the building’s energy use. eg. City of Toronto Efficiency grant $2500
    • “Green” Hotels Association, Membership requirements (greenhotels.com) : - Occupancy sensors to control lights, AC/heat, TV - Linens changed between guests or on request only (towels on floor or in tub) Estimated carbon savings: 5-10% The Hotel Association of Canada's (HAC) Green Key Eco-Rating Program Their audit is “administered entirely online” Awarded your key “within minutes!” Estimated carbon savings: ?? If you’re not reducing carbon use – significantly – it’s just ‘feel-good’ marketing.
    • Economic Disconnect # 1: Carbon is still free to emit. Solution: Put a price on carbon. Economic Disconnect # 2: Developers do not pay energy bills. Solution: Incentivize a new Geo-Utility, or Retrofit-Utility.
    • Education: If you don’t know about it, you can’t install it. Solution: Strong third-party support of “best practices” (eg. Manitoba Hydro) Technology support, not vendor support. Visible public advocacy. Capital: Need lots of patient capital. Solution 1: Unlock 5% of property value in a mortgage. Solution 2: Green Bonds! Like a Canada Savings Bonds, backed by government. Money earmarked for building retrofits, Interest paid with savings, Administered by commercial banks. See www.greenbonds.ca
    • Powering Canada’s Cleantech Industry and Economic recovery. Tap 5% of real estate value across the country: - Reduce Canada’s carbon emissions by 30% - - Create jobs and build a Canadian Cleantech industry - (Clean Energy Developments, Enerworks, Power-pipe, Morgan Solar…)
