House Performance GoalsHouse Performance Goals

• Up to 30% less energy consumed than a house built to the minimum Ontario Building Code 2006

• Up to 1,200 kWhs reduction in electricity use

• Up to 3 tonnes reduction of greenhouse gas emissions


How it worksHow it works

• Homes can only receive an ENERGY STAR® label if they have been enrolled.

• Enrollment is $100 by the builder when the house is sold

• Enrollment provides the homeowner, on behalf of the builder, an ENERGY STAR® Homeowner’s Package which includes the following items:– ENERGY STAR Qualified New Home label– ENERGY STAR Qualified New Home Certificate– Homeowner’s Letter from NRCan– “Look for ENERGY STAR® Product Guide”– “Tips to help you… Conserve Energy and Save

Money” – ENERGY STAR® Plaque (exterior application)
