Carbon Neutral Initiative

Transcription

1 Carbon Neutral Initiative November 2007 Provincial Government passed Bill 44 Greenhouse Gas Reductions Targets Act Reduce BC greenhouse gas emissions by at least 33% by 2020 and achieve an 80% reduction by (Reductions based on 2007 levels) Makes BC a world leader in Climate Action

2 Bill 44 Mandate for Public Sector All PSO s must be Carbon Neutral by 2010 This is achieved by reducing our emissions as much as possible and then purchasing carbon offsets for to cover the gap Current price for Carbon Offsets: $25/tonne

3 Emissions to be Reported Buildings (Owned and Leased) Direct emissions: Natural/Propane Gas Consumption Indirect emissions: Electricity Consumption Vehicle Fleet Direct emissions from car gasoline consumption Paper Consumption Indirect emissions due to paper consumption

4 GHG Emissions Rules for Reporting There is no allowance for increased Building Space ( 20% increase since 2007) CFL S.A. Trades Expansion C of E These is no allowance for increased Enrollment or Staffing ( 20% increase)

5 Okanagan College GHG Emissions Total Emissions 2007: tonnes CO2(e) (Baseline) 2010: tonnes CO2(e) 4% 2020: tonnes CO2(e) 33% 2050: tonnes CO2(e) 80% 2010 Carbon Offsets Purchased: x $25 $47,540 (Plus HST)

6 Okanagan College 2010 GHG Emission Breakdown Electricity 3.9% Fleet 4.8% Paper 4.7% (by source) Natural Gas 86.6 %

7 Okanagan College 2010 GHG Emission Breakdown (by centre) Salmon Arm 8.2% Vernon 13.6% Penticton 10.1 % Kelowna 68.1%

8 GHG Emissions Breakdown - analysis Majority (87%) of Okanagan College Carbon Foot Print is caused by gas fired heating, about 50/50 split between heat lost through building skins and the need to heat fresh air. KLO Campus is responsible for 68% of Carbon Footprint

9 GHG Emissions - KLO Breakdown - analysis

10 Energy/Carbon Dilemma Highest energy cost utility is electricity reducing our electricity consumption will give the biggest bang for our buck but does virtually nothing for our carbon footprint reduction.

11 Initiatives Undertaken

12 KLO Cafeteria HVAC/Lighting Upgrade Expected to Reduced Carbon Emissions in 2011 by 350 tons/yr Reduced amount of make-up air requiring heat: projected savings: 9000 GJ/yr Allowed Central Heating Plant to operate in Heat Pump mode for longer periods Better control of HVAC and lighting Greater comfort levels

13 Exhaust Air Heat Recovery (CFL) Captures Heat from Exhaust Air stream and preheats incoming ventilation air reduces amount of heat required. Still allows for proper amount of fresh air (IAQ requirement) Typically 50% of a buildings heating energy is used to heat ventilation air Could be used on almost all buildings but can be quite costly.

14 Skaha Residence Solar Project Project completed Nov 2010 Expected to reduce Natural Gas usage for DHW by 137 GJ/yr. Reduces GHG by 7 tonnes/yr

15 Other Initiatives Undertaken Implemented Pulse Energy metering on KLO Campus Solar Panels for Domestic Hot Water on the Daycare DDC Controls upgrade focused on reducing heating demand - ongoing Signed on as STARS participant Hired an Energy Manager to identify opportunities and educate college population Purchased 2 Hybrid vehicles Upgrade of all Incandescent and T-12 Fluorescent lighting Replaced Computer CRT s with LCD monitors (approx 2000 College wide)

16 Possible Initiatives Priorities should be directed to reducing gas fired heating loads on the KLO Campus Trades and the Central Heating Plant. Utility providers discourage fuel substitution i.e. change gas fired boilers to electric boilers.

17 KLO Trades Expansion and Upgrade Recent Design Charrette proposed energy upgrade to reduce carbon footprint. Has potential to reduce GHG by 300 tonnes. Number 1 priority on 5 year Capital Planning document Estimated cost $25 million

18 Central Plant Heat Pump Upgrade Would extend operational range of TEW heat pumps Estimated 350 tonnes in GHG reductions Offers flexibility of fuel source Estimate cost $2 million Part of 5 year Capital Plan

19 Welding Shop Upgrade Energy Study Would reduce the amount of heat required for make-up air (capture it with heat recovery) Potential reduces GHG emissions by 24 tonnes 5 year Capital Plan

20 Other Possible Initiatives Schedule classrooms more efficiently - shut down complete HVAC systems or buildings when we are operating at less than full capacity. Reduce reliance on gas fired equipment use more Geo- Thermal, Bio-Mass fuel Increase electronic control of lighting/hvac use of day light, motion sensors Replacement of inefficient equipment Boilers, motors, air conditioners Public awareness to turn off lights, computers, equipment, use double sided copying Car Pools, walk, bike etc (Transportation contributes to 38% of BC s Greenhouse Gas Emissions Use of alternative energy Solar, Wind Investigate possible offsets plant trees, co-generation
