Code
ENERGY STAR for New Homes – a prescriptive energy performance brand 25% better than code
R-2000 – a best-in-class performance brand, 50% better than codefor premiere builders, leading energy performance and innovation
Net ZeroNotional future ERS levels (to be determined through consultation) for the NRCan framework and suite of standards and labels
*86 is key point where renewables start to kick in
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
