Alternative Compliance Paths (ACPs)
Canada ACP – NECB and EnerGuide
For buildings in Group 1. Nonresidential, mixed-use, and multiunit residential buildings four stories or more, projects in Canada may instead demonstrate a percentage improvement in the proposed building performance rating compared with the baseline according to the National Energy Code for Buildings (NECB) 2011. Refer to the LEED v4 BD+C EA prerequisite Minimum Energy Performance Canada ACP for NECB 2011 for additional guidance.
For buildings in Group 2. Single-family residential and multiunit residential three stories or less, projects in Canada may instead demonstrate compliance using the EnerGuide Rating System and additional prescriptive requirements. Refer to the LEED v4 Homes Canada ACP for EA prerequisite Minimum Energy Performance for additional guidance.
To achieve points under EA credit Optimize Building Energy Performance, 90% of the Group 2 buildings must demonstrate performance equivalent to at least 15 points under the LEED v4 Homes Canada ACP for EA Credit Annual Energy Use.
At the end of ND GIB credit District Heating and Cooling credit language, add the following text:
Canadian projects can use the NECB 2011 as an alternative to by ANSI/ASHRAE/IESNA Standard 90.1–2010 for demonstrating the minimum efficiency requirements for equipment:
Each system component that is addressed by the NECB 2011 must have an overall efficiency performance at least 10% better than that specified by the Code’s mandatory limitations. Additionally, annual district pumping energy consumption that exceeds 2.5% of the annual thermal energy output of the heating and cooling plant must be offset by increases in the component’s efficiency beyond the 10% improvement. If a combined heat and power (CHP) system is used to comply with the credit requirements, show equivalence by demonstrating that energy consumption savings from the CHP plant at least equals the energy savings that would result from using a conventional district energy system with components that are 10% better than the NECB 2011. When determining equivalency, take into account the pumping energy as described above.
LEED v4 ND reference guide:
GIB credit District Heating and Cooling: add the following text to the Further Explanation > International Tips section:
Canadian projects using the Canadian ACP for NECB 2011, refer to sections 5.2 and 6.2 in place of ASHRAE 90.1–2010, Sections 6.4 and 7.4, for eligible equipment overall efficiency requirements. In addition, NECB, table 184.108.40.206 must can be used in place of ASHRAE 90.1–2010, Table 6.8.1C for minimum efficiency for water chilling packages."
GIB credit Renewable Energy Production: add the following text to a new Further Explanation > International Tips section:
"Canadian projects teams can use the following to calculate the project’s annual electrical and thermal energy cost when using the prescriptive option under GIB prerequisite Minimum Building Energy Performance:
For Non-residential buildings, use the Survey of Commercial and Institutional Energy Use (SCIEU) data contained within Portfolio Manager Technical Reference: Canadian National Energy Use Intensity By Property Type.
For Residential buildings, both multifamily and single family, use data from the Survey of Household Energy Use from Natural Resources Canada. [http://oee.nrcan.gc.ca/corporate/statistics/neud/dpa/menus/sheu/2011/tab..."
