3. The path of continuous improvement – 1960 to now The 2017 Code update will see an improvement of 15% over OBC 2012 and forecast the 2022 level

4. Lighting currently makes up approximately 10% of the Home energy use however CFL and LED technology uptake is reducing this. Lighting Space Heating 60% Lighting 5% Water Heating 20% Appliances 10% A/C 5% Although Canada is a heating dominated climate, forced air cooling is common in homes and accounts for approximately 5% of annual energy consumption Air Conditioning Major Appliances, including refrigerator, dishwasher and laundry account for approximately 10% of household energy use Major Appliances Water heating makes up approximately 20% of the Homes energy consumption. Averaging 225L/day, water heating is most often provided by storage type tanks with minimum efficiency of.57 EF Potable Water Heating Space Heating makes up approximately 60 % of the Homes energy load. Forced air furnaces make up the majority of applications with minimum efficiency of 90% Space Heating Canadian Home Energy Use

6. Building Code 2006 Provincial Building Code is the baseline for comparison. As Code improves, so does the baseline Energy Star Benchmarked against the Building Code, an Energy Star Home is approximately 20% more energy efficient R-2000 An R-2000 Home is approximately 50% more energy efficient than a code built home Net Zero Ready The Net Zero Ready Home is approximately 80% more energy efficient with additional features to allow for installation of solar thermal and PV. Builder Path to Net Zero 20% better Ground zero 50% better 80% better Produces as much energy as it consumes 100% better

10. Net Zero Energy Housing Council CHBA’s Net Zero Energy Housing Council (NZC) supports innovation in our industry with the goal of creating a market advantage for CHBA builder and renovator members pursuing Net Zero Energy performance. The Council's work will help to meet the housing aspirations of Canadians, and renew Canadian leadership in high performance housing.

11. A NZE home is one that is designed, modelled and constructed to produce as much energy as it consumes on an annual basis. Designed for use in new construction, low rise production housing. Includes space heating and cooling, ventilation, potable water heating, lighting and major appliances. Assumptions on plug load based on national average electrical consumption. Uses on site renewable energy, no offsetting. Allows for net metering and/or on site storage.
