R-2000 Standard has been updated


Natural Resources Canada (NRCan) is pleased to announce the release of the updated 2012 R-2000 Standard, which increases the energy efficiency requirement for R-2000 homes by an impressive 50%. The publication of this Standard once again positions R-2000 as a leading-edge national voluntary standard for energy efficiency in Canada.

Since its inception, the R-2000 initiative has been influential in encouraging, recognizing and supporting innovation in energy efficiency for residential housing. Recent increases in energy requirements in several building codes are placing those codes at near the same energy performance level as the 2005 R-2000 Standard. In order to ensure that R-2000 maintains its place as a best-in class standard for energy efficiency, NRCan initiated the development of the next generation of the R-2000 Standard. With the 2012 Standard’s increase in energy targets, R-2000 continues to play a key leadership role in promoting energy efficiency in the housing sector.
The R-2000 Standard Renewal Committee
The renewal of the R-2000 Standard was led by NRCan in conjunction with a multi-stakeholder committee. The R-2000 Standard Renewal Committee (herein referred to as the “Committee”) met for the last two years with the objective of providing recommendations to NRCan on changes to the technical requirements for the next generation R-2000 initiative. A proposal submitted by the Canadian Home Builders Association (CHBA) to NRCan was used as a seed document. More details on the Committee process, including an excerpt from the Committee Terms of Reference can be found at: http://oee.nrcan.gc.ca/residential/r-2000-next-gen.cfm
Phased-In Implementation
The Committee developed a comprehensive set of recommendations which will be phased in as follows:  
Phase 1 (Standard published in February 2012 and mandatory for July 1, 2012)
Phase 1 will see the re-release of the current R-2000 Standard, with some changes. Key among these is a 50% increase in the energy target. Additional changes are listed below under “Changes to the 2012 R-2000 Standard”.  
Phase 2 (2014, in tandem with the launch of the revised EnerGuide Rating System) Phase 2 will see the release of the fully revised R-2000 Standard.
The phased-in approach enables program participants to test the new energy target of R-2000 in Phase 1, and allows for sufficient time to train builders and energy advisors on all aspects of the 2014 R-2000 Standard prior to its implementation.
Attached is a detailed depiction of the timeline for the release of the new standard in its two phases and the phase out of the 2005 Standard.
The updated 2012 R-2000 Standard reinforces the tested values and benefits of the R-2000 initiative that include third party inspection, licensed builders and home certification by the Government of Canada.
The following is a summary of the changes that have been made to the 2012 R-2000 Standard relative to the 2005 version:
        • Changes to the existing energy target formula in Appendix B: This energy target formula is now multiplied by 0.5 to reflect the increased energy target. 
·       Revisions to the minimum requirements for several Pick List items since some requirements had become obsolete. These items include:
·       Air filtration (A2a) - Additional option of MERV 13 air filter provided. The MERV 13 rating is in line with that recommended by the R-2000 Committee for the 2014 R-2000 Standard;
1       Low-toxicity finishes (A3, A4, A5, A7, B1-4)– re-phrased as third-party certified low-VOC (volatile organic compound) content, with additional choices for the third party;
2       Removal of measures to avoid window condensation measures (A9a) since these are now covered under window performance requirements (4.4); and
3       Cooling Systems (B13) – now need to be ENERGY STAR qualified.
        • Updated minimum requirements for windows as previous requirements were out of date.
        • Revisions to the water conservation requirements since the previous requirements were equal to or lower than code. New requirements are in line with those recommended by the R-2000 Committee for the 2014 R-2000 Standard.
        • Revision of eligible buildings under “scope” to be more precise. Eligibility remains the same.
        • Updated referenced standards where necessary.
        • Updated relevant website links.
NRCan looks forward to working with you and building on past successes to promote the updated 2012 R-2000 Standard in the market. Should you have questions, we invite you to contact your Natural Resources Canada Account Manager.
