ENERGY STAR® for New Homes Standard Version 12.6

April 26, 2015


Natural Resources Canada (NRCan) is pleased to announce the release of the ENERGY STAR for New Homes (ESNH) Standard Version 12.6 which comes into effect on April 22, 2015.

The ESNH Standard Version 12.6 includes the following key changes:

Changes to the ENERGY STAR fenestration requirements in builder option packages

To reflect new technical specifications for ENERGY STAR certified windows, doors and skylights which came into effect February 1, 2015*, changes to the requirements for windows in the BOPs have been made. The changes will be implemented in two phases, as follows:

1. As of April 1, 2015: (i) Allowance to use the next lower climate zone for fenestration in the core builder option packages (BOP) for 12 months and (ii) provision of BOP points for using fenestration that is certified for climate zones that are higher than those in the core BOP.

• For example, Zone 1 windows can be used in lieu of Zone B windows in the core BOP, and BOP points will be provided for using Zone C or Zone 2 windows.

2. Houses enrolled as of April 1, 2016: Fenestration requirements in the core BOPs will increase, however BOP points associated with the increase will apply.

• For example, where Zone B or Zone 1 windows were allowed, the requirement will change to Zone 2 windows but the BOP points for using Zone 2 windows (same points as those for Zone C currently listed in the standard) will be allocated.

Although NRCan research and feedback from the Technical Advisory Committee indicates that window upgrades are a common BOP option, a one year phase-in period is being provided to help ensure builders have sufficient time to adjust.

There is assurance with regard to the energy performance of the fenestration product since (i) the energy performance requirements for the lower zone are at least equivalent if not better, and (ii) the product has still gone through the ENERGY STAR certification process. It is anticipated therefore that there should be no overall impact on the energy performance of the house.

All changes relative to Version 12.5 are summarized in the Preface and are listed in numerical order according to the relevant section of the ESNH Standard. Attached is the ENERGY STAR for New Homes Standard Version 12.6.

The compliance portion of the online system is still under development; further notification will be provided when the system is completed.
