5. 5 Process: Home Energy Assessment Walk Through Gather Data Air Leakage Test

6. 6 ecoENERGY Retrofit Homes  What is an energy assessment?  Walkthrough of the home (all heated spaces)  Take measurements  Identify efficiency of space heating and water heating equipment  Basement to attic included  Blower door test and air leakage identification  Discussion with homeowner  Demonstration of stand-by power  Modeling of the home  Modeling of recommended upgrades  Report to homeowner (incl. pictures)  Information kit to homeowner  Time: 60-90 minutes  Cost:  Pre-assessment ~ $200 to $350  Post assessment ~ $150 to $200

7. 7 ecoENERGY Retrofit – Homes: Grants  Grants are measures-based  ENERGY STAR qualified heating equipment  Heat pumps: air-to-air, geothermal  Wood-burning appliance replacement  Electronic thermostats (electric heating)  Domestic hot water heaters (gas, solar)  ENERGY STAR qualified cooling  Ventilation: heat recovery ventilators  Insulation: attic, walls, basement, crawl space,  exposed floors  ENERGY STAR qualified windows, doors and skylights  Air leakage remediation – professional  Water usage – low-flush toilets  Drain-water heat recovery systems

8. 8 Provincial, Territorial & Utility Collaboration  11 organizations collaborating on home retrofit programs  Many subsidize cost of evaluation  Ontario – 50% up to $150 (to homeowner)  Québec - 50% of pre-assessment, 100% of post to service organization  British Columbia – 50% of pre-assessment, payable after the post-retrofit – paid to homeowner.  Coupled with a variety of incentives:  Full or partial matching grants (i.e. measure specific)  Loans (with or without interest)  Savings (i.e. cubic metres of natural gas)  Points improvements (i.e $100 per point after 2 points)  Grant can be combined with other incentives provided no more than 100% of costs covered  Support from gas, electric utilities (check locally)  Tax free  One stop shopping for administration – one signature

9. 9 ecoENERGY Retrofits - Homes  Program reach:  2008-09: 257,400 home evaluations and 76,368 received incentives  Apr 2009 to Feb 15, 2010: 302,770 evaluations and 162,130 received incentives  ecoENERGY total: 581,900 homes evaluated and 256,140 qualified for incentives  Popular with homes built before 1990 – almost 88% of all evaluations

10. 10 Retrofit Measures  Replace heating system with ENERGY STAR qualified model: 67%  installation of 92% AFUE furnace with energy efficient motor  Add insulation to attic: 27%Insulate basement: 28%  Reduce air leakage (air sealing): 45%  Replace windows, doors with ENERGY STAR qualified units: 35%  Homeowners typically undertake more than one action  Solar DHW ~ 950 installations  GSHP ~ 6,745 installations

11. 11 Indicators  581,900 pre-retrofit evaluations since April 1/07 (a total of more than 800,000 homes since 1998)  80 Service Organizations licensed to date  1,880 active energy advisors  Available across Canada  Target for providing homeowner service within 2 weeks  Energy Efficiency  Energy savings ranging from 32 to 98 GJ/year – average 50 GJ/year/house – about 22%  Improvement in Rating – average 10 points  GHG emissions – 3.1 tonnes per house per year  Federal incentive ~ $1,400 per house (matching incentives added in most jurisdictions)  Homeowners have 18 months to complete upgrades and apply for grant

12. 12 Next Generation EnerGuide Rating System

13. 13 Development of the Next Generation EnerGuide Rating System  NRCan initiated revision process for the EnerGuide Rating System (ERS).  Vision  The vision for the next generation EnerGuide Rating System (ERS) process is to develop the most effective energy rating system, supported by the best tools and acceptable to and recognized by all stakeholders.  Parameters  able to rate existing and new houses including net zero homes on the same scale  only rate energy and factors that are related to energy use in the home  ability to account for electrical loads, air conditioning and renewable energy  complementary to energy codes.  offer stability for stakeholders using the system  able to help homeowners make informed decisions  Process and Progress to date:  First meeting of the ERS Policy Advisory Committee will be on March 11 and 12.  Consultations and committee formation based on a Standard Council of Canada type of process  Completed the background studies  Initiated survey of existing stakeholders

14. 14 R&D Energy Technology Highlights … Comparing Performance of Mechanical Systems

15. 15 Performance of House Mechanicals  Objective  Energy efficiency and system effectiveness performance of residential space heating, hot water and ventilation systems  Three different systems  Conventional separate components: condensing furnace, induced-draft DHW and HRV  Combo: boiler, air handler and HRV  Integrated Mechanic System (IMS): space heat, hot water and HRV all integrated in a one unit  Method  Side-by-side testing at Canadian Centre for Housing Technology (CCHT)

16. 16 Performance Verification at Canadian Centre for Housing Technology  Government of Canada test facility (www.ccht-cctr.gc.ca)  Research quality testing  Side-by-side comparisons  Commissioning -> benchmarking -> experiment

17. 17 The Standard System  condensing natural gas furnace  AFUE 90%  power-vented natural gas hot water tank  EF of 0.58  heat recovery ventilator (HRV)  SRE of 69% at 0 C, and 62% at -25 C

18. 18 The Combination System  Boiler - 90% AFUE, Energy Star® qualified.  Air handler  Pump between storage tank and boiler  Storage tank - 40 G (151L).  HRV - SRE - 69% at 0 C, and 62% at -25 C.

19. 19 Integrated Mechanical System  Condensing boiler provides both space heat and hot water (Boiler AFUE 93%)  Integrated air handler has ECM motor  Integrated HRV with sensible recovery efficiency of 60% at 0 o C
