1. Overview of Energy Efficiency & Renewable Energy (Draft version) Prepared by Natural Resources Canada in association with Indian and Northern Affairs Canada Ressources naturelles Canada Natural Resources Canada CANMET- EDRL

2. Purpose u To provide information on Energy Efficiency (EE) and Renewable Energy (RE) measures and technologies u To illustrate how EE and RE can serve community energy needs u To increase awareness about EE & RE technologies how EE and RE save money how EE and RE save money introduction of EE and RE into decision process introduction of EE and RE into decision process implementation considerations implementation considerations

3. Reasons u Environmental climate change and local pollution climate change and local pollution u Economic life-cycle costs life-cycle costs depletion of fossil fuels depletion of fossil fuels reduced drain of $$$ from community reduced drain of $$$ from community u Social employment generation employment generation energy independence energy independence security through diversification of energy supply security through diversification of energy supply contribution to sustainable development objectives contribution to sustainable development objectives less $ out from community less $ out from community

4. Contents u Overview u Energy Efficiency housing and buildings housing and buildings communities communities  Renewable Energy electricity generation electricity generation space heating and cooling space heating and cooling u Information Sources IndustryBuildings Transportation Energy Demand in Canada

5. How and Where Energy is used u Buildings (lights, appliances, heating, cooling) u Communities (waste heat, district heating) u Off-Grid (fishing camps, water-pumpers, communications) u Industry u Transportation Water Heat Light/appliances Space Heat House Energy Use

6. Definitions u Renewable Energy: using non-depleting energy resources to do the same task u Energy Efficiency: using less energy resources to do the same task Other Residential Space Heating Non Residential Space Heating Power Generation Energy Expenses in a Remote Community

7. Introduction u Common characteristics of EE and RE: low to high initial costs low to high initial costs low to no operating costs low to no operating costs environmentally clean environmentally clean no resource depletion no resource depletion cost effective in many cases cost effective in many cases reliability and longevity reliability and longevity

8. Deciding on EE / RE u Relevant factors: local environmental considerations local environmental considerations economics economics keeping money in community keeping money in community local employment benefits local employment benefits desire for energy independence desire for energy independence aesthetics aesthetics operational simplicity operational simplicity

9. Cost of an Energy System u Cost effectiveness = doing things RIGHT from the start in new construction in new construction in renovations in renovations in other opportunities to upgrade in other opportunities to upgrade  replacing windows,  light bulbs, etc.

10. Concept of life-cycle cost

11. Cost of an Energy System u Cost of purchase  total cost of system u Total cost of energy system (life-cycle cost)  purchase cost + installation cost + annual fuel costs + operation expenses + maintenance & repair costs + major overhaul costs + replacement at end of life + decommissioning costs

12. Reduce energy consumption for the same level of comfort EE in Housing & Buildings

13. u Introduction 55 % of energy demand is for heating in remote communities 55 % of energy demand is for heating in remote communities all communities and buildings can benefit all communities and buildings can benefit schools often largest energy user schools often largest energy user applies to new and existing buildings applies to new and existing buildings must respect air tightness concerns must respect air tightness concerns

14. EE in Housing & Buildings u Factors affecting EE application climate climate building design, construction and siting building design, construction and siting occupancy occupancy condition of buildings condition of buildings sources of energy and energy using equipment sources of energy and energy using equipment

15. EE in Housing & Buildings u Benefits of EE occupant comfort, health and safety occupant comfort, health and safety reduced operating cost and fuel requirements reduced operating cost and fuel requirements increased building longevity increased building longevity

16. EE in Housing & Buildings u Energy auditing analyzing energy demand analyzing energy demand identifying improvements identifying improvements

17. u Low cost measures: lower hot water tank temperature lower hot water tank temperature add insulation to water heater add insulation to water heater install hot water flow restrictors install hot water flow restrictors turn off lights turn off lights caulk/seal leaks caulk/seal leaks set-back thermostat set-back thermostat service/clean heating system service/clean heating system Energy Efficiency in Existing Housing & Buildings

18. u Medium cost measures : add insulation to basement, attic, walls, floor add insulation to basement, attic, walls, floor upgrade windows and doors upgrade windows and doors add air-to-air add air-to-air heat exchanger heat exchanger install high install high efficiency lights efficiency lights Energy Efficiency in Existing Housing & Buildings

19.  High cost measures: New heating equipment New heating equipment Add vapour and air barriers to whole building Add vapour and air barriers to whole building Install high efficiency heating equipment Install high efficiency heating equipment

20. Energy Efficiency in New Housing & Buildings u Conventional measures use good house/building orientation use good house/building orientation increase insulation levels increase insulation levels use modern air sealing and ventilation techniques use modern air sealing and ventilation techniques

21. Energy Efficiency in New Housing & Buildings u R2000 / C2000 exceeds conventional standards exceeds conventional standards in widespread use in widespread use 40 % energy saving 40 % energy saving quality, quiet and comfort benefits quality, quiet and comfort benefits builder training and qualification builder training and qualification payback - less than 7 years payback - less than 7 years

22. Energy Efficiency in New Housing & Buildings u Advanced housing exceeds R2000 standards exceeds R2000 standards demonstration units only demonstration units only common features common features emerging technologies emerging technologies u Green housing applies in new/retrofit housing applies in new/retrofit housing water saving devices water saving devices Ecologo products Ecologo products waste treatment systems waste treatment systems recycling recycling

23. Energy Efficiency in Communities u Community energy audits energy audits energy plan energy plan u Diesel efficiency u District Heating Ouje-bougoumou

24. Renewable Energy Primary RE Resources Used in Canada: Sun, Water, Biomass, Wind and Earth Energy Sources Renewable Energy currently supplies 17 % of Canada’s energy supply
