ENERGY STAR® for New Homes Standard

ENERGY STAR for New Homes is promoted by the Office of Energy Efficiency of Natural Resources Canada as an initiative designed to encourage energy efficient construction in new housing, which helps reduce greenhouse gas emissions.

The initiative is supported by the ENERGY STAR for New Homes Standard which sets out requirements that enable new homes to be approximately 20% more energy efficient than those built to the Provincial or National Building Code. The increased energy efficiency of these homes translates into reduced energy costs for homeowners.

Opaque Assemblies

The Tables for Calculating Effective Thermal Resistance of Opaque Assemblies provides a method for calculating the effective thermal resistance of opaque assemblies. It is currently being used to demonstrate compliance with the prescriptive approach under the ENERGY STAR for New Homes Standard, and is also referenced in the National Building Code of Canada as a source for calculating additional assemblies and configurations.

This document provides easy-to-use look-up tables for the effective thermal resistance of assemblies containing both framing member and cavity insulation.
