2 Vision NWT Society will become a global leader in clean, efficient, sustainable energy practice. Introduction to AEA Mission To promote and facilitate the adoption of efficient, renewable and carbon neutral energy practices by all members of NWT society. Background not-for-profit, non governmental organization, set up in Yellowknife & Inuvik Offices

3 AEA Areas of Activity We know about: Energy Efficiency Renewable Energy Carbon Offsets We focus on: Residences Commercial / Institutional Buildings Communities Services Free advice Information Promotion Yardstick screening Affordable, high quality audits & pre-feasibility studies Incentive programs Project management Research Monitoring

4 Outline Overview of Energy Use in the NWT Types of Buildings and their Energy Use Energy Efficiency (EE) Standards for Buildings Renewable Energy (RE) Standards for Buildings Implementation & EE/RE Toolkit

5 NWT Energy Profile

6 Energy Use in Buildings Homes Oil, propane, natural gas, wood used for space heat, in some cases domestic hot water (DHW) Electricity for appliances, entertainment systems, lighting Buildings Oil, propane, natural gas, wood used for space heat & DHW Electricity for lighting, heating and ventilation, office equipment, refrigeration systems, etc. How much energy we use depends on our habits, and also the energy efficiency of our home or building

7 Current Building Practice (NWT) GNWT Recent public housing around EGH 75, Committed to build next generation to EGH-80 plus GNWT Northern Building Best Practices ~ similar to MNECB + 25% Non-government Private housing around EGH Yellowknife by-law requires EGH-80 & MNECB+25% Private buildings wide range Small communities taking over infrastructure & new building

8 Energy Efficiency and Renewable Energy Standards Why set standards for Energy Efficiency & Renewable Energy? Energy Efficiency & Renewable Energy mean different things to different people (especially Architects & Engineers!) Limited technical resources in smaller communities (building inspectors, etc) Build better buildings with lower impact on environment

9 Building Energy Efficiency Homes, duplexes, triplexes, small apartments, small bed and breakfasts Energuide for New Houses 80 (EGNH-80) standard Standards Before a house is built, plans need to be reviewed by EGNH advisor House needs to then be checked by an evaluator once built

10 LEED Building Energy Efficiency Standards Large Buildings (footprint area greater than 600 m 2 ) LEED Certified, Silver, Gold, or Platinum Building should use at least 25% less energy than the Model National Energy Code for Buildings (MNECB) reference To be LEED Certified, building also to incorporate sustainable siting, water efficiency, green materials, air quality

11 Building Energy Efficiency Standards Small Buildings (footprint area less than 600 m2) Use 25% less energy than Model National Energy Code for Buildings (MNECB) reference building Use online screening tool by Natural Resources Canada Office of Energy Efficiency to check the design of the building New MNECB coming in 2011

12 Standards for Appliances, Use only Energy Star rated appliances and equipment Use only fuel-fired water heaters in diesel communities Use only low flow toilets, shower heads, and faucets Equipment, & Water

13 Standards for Passive Solar Design Build all homes and other buildings with south facing windows Sunlight comes through the windows and heats the building even during winter! The sun is a renewable energy source

14 Standards for Co-generation A generator only converts 35% of fuel energy (diesel) to electricity; the rest is dumped as waste heat Co-generation means generating electricity andheat from a generator waste heat captured & used Reduce overall GHG emissions in the Community Consider on-site co-generation if base electricity load is 10 kw or greater (large buildings or clusters)

15 Standards for Renewable Energy You can specify a minimum requirement of renewable energy used in each building Could be 5%, 10%, 25%... Promotes use of energy from the sun, wind, and our forests Lower the GHG emissions in your Community

16 Building Energy Efficiency Standards Cost Comparison Yearly energy cost of office buildings 6500 square feet m^2 area Using current Fort Simpson rates for heat & power $70,000 $60,000 $50,000 $40,000 $30,000 $20,000 $10,000 $- Electricity Heat By building better buildings, start saving $ from day one $12,000 $10,000 $8,000 $6,000 $4,000 $2,000 NWT Average MNECB+25 LEED Gold Yearly energy cost of Homes 840 square feet - 80 m^2 Electricity Heat $- EGH68 home EGH80 home

17 Implementation Implement EE/RE standards for the whole Community Resolution or Bylaw Specify EE/RE standards in tenders and proposals RFP Verification Hire a LEED Professional when building a large building (>600 m 2 ); AEA can help with EGNH-80 and small buildings
