COMMERCIAL AND INSTITUTIONAL BUILDING ENERGY USE SURVEY 2000 (CIBEUS) Detailed Statistical Report, December 2002

A4. Data Collection and Response Rates

This section addresses data collection and response rates.

A4.1. DATA COLLECTION

The area frame was created in the fall of 2000. Interviewers made a list of all the buildings in the EAs sampled. For each building listed, interviewers were to give the main activity of the building, the year of construction and its area. Interviewers were also to try to obtain the name and telephone number of the person most capable of answering the survey questions.

When a building was selected for the sample, telephone contact was established with the respondent to determine the best time to carry out the interview.

Interviews were held in person in the spring of 2001.

During the interview, in addition to the main questionnaire, respondents were asked to provide their energy consumption in two of three ways suggested. The first consisted of signing a form authorizing Statistics Canada to gather information directly from the energy provider; the second asked respondents to provide the information requested in a table; the third allowed respondents to provide a photocopy of their energy consumption bill.

The energy providers of the respondents who signed the authorization form were contacted. Most of them were cooperative and provided an electronic copy of the requested energy consumption.

A4.2. RESPONSE RATE

Of the 5,124 buildings sampled, there were 4,101 respondents (of which 196 were mass imputed; see section A5.2), 560 non-respondents and 463 units outside the survey coverage.
