Chapter 2 - Residential Sector

The Data Situation

Aggregate data on residential energy use are reported in Statistics Canada’s Report on Energy Supply and Demand in Canada (RESD)(Cat. No. 57-003-X). To provide more detail on how this energy is used, the Office of Energy Efficiency (OEE) has developed the Residential End-Use Model (REUM). This stock accounting model assesses trends in energy use in the Canadian residential sector by allocating the energy use reported in the RESD to end uses using annual stock characteristics and sales data, coupled with usage profiles and unit energy consumption for equipment stock. It is disaggregated at the provincial level and includes four building types, five end uses, nine vintage categories (house age categories) and six fuel types. Some end uses are further disaggregated by equipment type.

Household characteristics are derived from the Household Facilities and Equipment Survey for the years prior to 1997 and from Statistics Canada’s Survey of Household Spending from 1997 and onward. The two surveys collect similar information but use different methodologies, therefore requiring significant data processing to merge the information. Because Statistics Canada stopped releasing data about vacant housing stock in 2001, the calculation of housing stock for 2001 and onward uses the number of households, new construction completions, and demolished dwellings. Floor space information is acquired by combining housing stock estimates with data from two other Statistics Canada surveys: the Building Permits Survey and the Survey of Household Energy Use (SHEU).

Energy consumption information was drawn from the data collected by various industry associations and external studies. Specifically, the Association of Home Appliance Manufacturers Canada, the Heating, Refrigeration and Air Conditioning Institute of Canada, the Energy Technology Database developed by Marbek Resource Consultants Ltd. and the internal expertise of OEE staff were utilized in this regard.

The REUM also takes into account the influence of weather on residential energy demand. It uses the number of heating degree-days in Monthly Values of Degree-Days Below 18.0°C and the number of cooling degree-days in Monthly Values of Degree-Days Above 18.0°C (both reports from Environment and Climate Change Canada).

The residential prices of heating oil and natural gas are weighted averages of regional prices from Statistics Canada’s CANSIM Table 326-0009 for heating oil prices and Table 129-0003 for natural gas prices. The residential price of electricity is a weighted average of the data found in Hydro-Québec’s Comparison of Electricity Prices in Major North American Cities.

Due to rounding, the numbers in the tables may not add up or calculate to their reported totals or growth rates.
