Recognizing Success

Energy Use & Greenhouse Gas Emissions in Canadian Homes

1990 – 2010

Canadian Renovators’ Council, October 2012


Three part report

Three Part Report:

  • CHBA’s Annual update on Residential Sector performance.

  • Closer examination of how new homes have changed based on CHBA/CanmetENERGY analysis.

  • Future potential for energy retrofitting.

How have new homes changed

How Have New Homes Changed?


Comparing apples to apples

Comparing “Apples to Apples”

  • Total stock trends are useful, but they don’t tell us much about how new homes have changed over time.

  • Existing home energy performance is a ‘moving target’.

  • When comparing old and new homes, what do we learn if we base this on the ‘as built’, rather than ‘as found’ specifications?


Our apple

Our “Apple”

  • 2,100 sq. ft. two-storey home in Ottawa circa 1973 (Four-Square).

  • Initial “As Built” specifications from CMHC/HUDAC costing studies of that time.

  • Additional specifications generated by CanmentENERGY, OBC 2012, R-2000 (2012).

  • Only envelope and mechanical specifications altered to those ‘typical’ of new construction in each period.

  • ‘As Found’ specifications from initial (pre-grant) ERS evaluation.

  • All data generated using HOT2000 V. 10.51


Recognizing success

  • ‘As Built’ = ERS 41

  • ‘As Found’ = ERS 63 = 28.7% improvement

  • ‘Post ecoENERGY Grant’ = ERS 72 = 44.5% improvement

  • Same home built to 2012 OBC would consume 66% less energy than mid-1970s spec.

And the impala s a success story

. . . and the Impala’s a ‘success story’


On apples to apples basis

On “Apples to Apples” Basis:

15.8% Increase in ‘Combined’ Fuel Efficiency

66% decrease in total energy consumption (ERS 41 to ERS 79)

78.5% decrease in space heating energy consumption
