1. Next Generation R-2000 Standard Presented to: Technical Research Committee February 23rd, 2011 1

2. Standards and Labels Notional future ERS levels (to be determined through consultation) for the NRCan framework and suite of standards and labels 100 86* 83 80 Net Zero – R-2000, as best practice, serves as basis right up to Net Zero *86 is key point where renewables start to kick in EnerGuide Rating Scale R-2000 – a best-in-class performance brand, 50% better than code for premiere builders, leading energy performance and innovation ENERGY STAR for New Homes – a prescriptive energy performance brand 25% better than code Code

3. R-2000 Standard Renewal Committee • Standard Council of Canada based approach with Advisory Committee • Committee in place since December 2009 • Best-in-class performance brand, for premiere builders, at the forefront of energy performance and innovation • Vision: To provide the home building industry and consumers with a technical standard that represents the leading edge of commercially-viable new home construction, based on available and proven technology, products, materials and building techniques • Recommendations on Technical Standard

4. Key Recommendations • Increase energy target by 50% • Increased from ERS 80 to ERS 86 • Additional interim building envelope target • Must meet ERS 82 using standard mechanical conditions (calculated automatically by software) • Airtightness Requirement • Detached: keep 1.5 ACH @ 50 Pa • Attached: under discussion

5. Key Recommendations • Account for AC • Energy target will account for AC when: • the cooling load > 2.0 MJ/m3 and • Indoor temp > 25.6oC for more than 75 hours/month for at least 2 months in a year. • not necessary to install an AC unit • Account for Renewable Energy • SDHW & geothermal currently accounted in hot water and space heating in software • New equation will credit electricity from on-site renewable electricity sources (e.g., PV, wind)

6. Key Recommendations • No minimum performance requirements • Exception: fenestration must be ENERGY STAR (due to auditing; but no specific climate zone requirement) • Broader Pick List • Current: Choose 3 of 12 IAQ items; 2 of 15 environmental items • Proposed new list: Choose 8 of 27 items • IAQ: 5 items • Energy Efficiency: 7 items • Environmental Stewardship: 7 items • Resource Management: 4 items • Water Conservation: 4 items

7. Next Steps • Finalize recommendations on standard • Public review: March/April 2011 • Exploring option for a Pilot

8. ESNH • First Committee meeting took place in December 2010 • Vision: to provide consumers with access to energy efficient new homes and builders with a means to building these homes in a timely, simple and cost-effective manner using common building practices. • Committee Goal: make recommendations on national minimum requirements and provincial BOPs • Initial work to be complete by December 2011
