  3. Vision of ERS in the marketplace • The ERS will provide a national system, supporting (and supported by) regional solutions, to: • Help Canadian homeowners, industry and stakeholders, become “energy literate” regarding houses and the decisions related to them • Provide specific, readily accessible energy performance information to support decision making in designing, constructing, purchasing, renovating or operating a house

  4. ERS Objectives • Provide the consumer, industry and other stakeholders with clear, easily understood, home energy information at a reasonable cost • Serve as the backbone of all home energy programming and policy development in Canada • Provide a robust, efficient and effective delivery model • Account for total energy use and production

  5. Straightforward, meaningful portrayal of home energy use Allows comparison of all homes regardless of type or location Good design is reflected in the rating – design matters Positions the house against the same house built to code Energy improvement can be expressed in straight percentages Harmonizes with the appliance scale Fuel neutral, size neutral, seamless with any code and with any code changes • Provide the consumer and stakeholders with clear, easily understood, cost effective home energy information Whole house consumption Energy Rating:

  6. Provide the consumer and stakeholders with clear, easily understood, cost effective home energy information In addition to the energy use figure, provide a “nutrition label” style array of information • Increases energy literacy • Allows the consumer or regulator to extract the selective information they require • Provides information to support policies • The label will be supplemented with a Guide to the Label and a Homeowner Information Sheet. • Additional information will be available through a suite of on-lines services at myEnerGuide.ca

  7. Provide the consumer and stakeholders with clear, easily understood, cost effective home energy information • The My EnerGuide Homeowner Information Sheet will include such information as: • A description of how energy is used in the home • A listing of data that was collected to rate the house incl.: • Airtightness levels • Insulation levels • Window sizes and performance • Mechanical system performance • The next steps a homeowner can take to upgrade the energy performance of their house

  8. Serve as the backbone of all home energy policy and programming in Canada • Standard home evaluation • Streamlined base rating with blower door test • Add-on modules: • Renovation Upgrade Evaluation • Construction Upgrade Service for New Homes • Efficient Living Assessment • Construction Blower Door test • Complimentary to code • Report on GHGs, regionally

  9. Heat Loss Windows, exterior doors and skylights, Ceiling assemblies, with and without attics, Above grade wall assemblies, Below grade wall assemblies, Exposed floor assemblies, Basement slab insulation, and Airtightness. Base house energy use and production Space heating and cooling Hot water Mechanical ventilation Passive solar gains Gains from active renewable energy systems Account for total on-site energyuse and production (1 of 3)

  10. Occupancy driven energy use Set to Standard Operating Conditions Set point temperatures Hot water load Electrical loads Lighting Appliances Other electrical loads (computers, dvd, small appliances…) Use of Base load packages (standard, mid, high) to set the base electrical load Account for total on-site energyuse and production (2 of 3)

  11. Account for total on-site energy use and production (3 of 3) • The rating should cover the house itself, not the property • Large a-typical loads will not be included in the rating but will be noted on the homeowner information sheet (e.g.. pools, hot tubs) • Renewables will be included where it can be shown that renewable supply is dedicated to the home • solar hot water • solar PV • wind

  12. More Information • Development of Next Generation Energy Efficiency Housing Standards: • http://oee.nrcan.gc.ca/residential/housing-initiatives.cfm • To register as an observer e-mail: • ERSsecretariat@nrcan.gc.ca

  13. Next Steps • Finalize recommendations on standard • Public review: March/April 2011 • Pilot • Launch: not before April 2012

  14. Next Generation ERS • Questions?
