“…In total, 347 questionnaires were returned, which corresponds to a 17% response rate, which is comparable to response rates of similar postal questionnaire surveys of homeowners. 12,14 For example, a recent survey by McGilligan et al, 12 which investigated energy efficiency measures in newly purchased dwellings, had a response rate of 19%. In the survey presented here, 10 responses were excluded from the final analysis for various reasons of unsuitability: invalid or inappropriate responses or comments, the respondent was a tenant and not the homeowner or the house had been put on the market before the date EPCs were required, i.e.…”

Since October 2008, Energy Performance Certificates (EPCs) have been a mandatory requirement for all dwellings sold or rented in England and Wales. Having now been in place for some time, it is of interest to assess the scheme’s impact and effectiveness. This paper presents the results of a questionnaire survey, targeted at almost 2000 homeowners in Southampton on the South coast of England, who bought their home within the first year of the scheme’s introduction. The survey had a response rate of 17% and established homeowner awareness of EPCs, but highlighted that they had little impact on decision-making or price negotiation. Where retrofitting measures have been undertaken, results are inconclusive as to whether retrofitting was done as a result of EPCs. Energy efficiency was not found to be a priority for homebuyers. Practical applications: The survey presented in this paper highlights that further refinement of EPCs and the certification process appear to be needed, in order for the scheme to become a widespread success in the domestic sector. Whilst there is an awareness of the scheme in general, there appears to be limited recognition of its potential. This poses a challenge for the building industry and certification bodies, which need to seek ways to better communicate the benefits of the scheme, in order to instigate the refurbishment works that are required to meet the national carbon emissions reduction targets in the UK.

“…These incremental improvements require control through the continuous monitoring of the energy consumption as well as interior and exterior temperatures through the energy signature (Roulet, 2002;Parnell and Popovic Larsen, 2005;O'Sullivan 2002). It is vital that the same monitoring principle is used over a longer period for recording consumption, controlling indoor conditions, interpreting the functioning of the equipment (set points, etc.…”

“…The innovative billing approach is complimentary to, and synergestic with, inspections and energy ratings of buildings, as recently required by the European Commission (Parnell and Larsen 2005). Energy inspections and ratings cost in the range of $1 00-$250 and are typically done once per owner (or once per building).…”

A program called "Innovative Billing" has been developed to provide individualized energy information for a mass audience-the entire residential customer base of an electric or gas utility. Customers receive a graph on the bill that compares that customer's consumption with other similar customers for the same month. The program aims to stimulate customers to make efficiency improvements. To group as many as several million customers into small "comparison groups", an automated method must be developed drawing solely from the data available to the utility. This paper develops and applies methods to compare the quality of resulting comparison groups.A data base of 114,000 customers from a utility billing system was used to evaluate Innovative Billing comparison groups, comparing four alternative criteria: house characteristics (floor area, housing type and heating fuel); street; meter read route; and billing cycle. Also, customers were interviewed to see what forms of comparison graphs made most sense and led to fewest errors of interpretation. We find that good quality comparison groups result from using street name, meter book, or multiple house characteristics. Other criteria we tested, such as entire cycle, entire meter book, or single house characteristics such as floor area, resulted in poor quality comparison groups. This analysis provides a basis for choosing comparison groups based on extensive user testing and statistical analysis. The result is a practical set of guidelines that can be used to implement realistic, inexpensive innovative billing for the entire customer base of an electric or gas utility.
