Abstract

The UK's Energy Efficiency Best Practice Programme (EEBPp) has been running since 1989. It is a dissemination programme issuing best practice guides, case studies, seminars and workshops to promote energy efficiency in buildings. The programme also promotes energy efficiency in industrial processes, but BRE only undertakes the impact assessment of energy efficiency in buildings.

BRE assesses the programme's impact by means of an annual survey that identifies the energy measures implemented, calculates gross UK energy savings and attributes relevant savings to the programme. The survey is completed over the telephone and achieved a very good response rate of 98% with approximately 2,800 completed questionnaires in 1999. The survey accuracy has been calculated at � at 90% confidence limits.

The target audiences are the owners of both new and existing buildings segregated into 13 sectors. Respondents are asked a series of questions regarding the energy saving measures they have implemented and their views on the usefulness of the programme.

Data analysis is completed using SPSS and Excel. The method takes into account multiple measures and hours of use as well as persistence of energy savings. We then calculate the saving attributable to the EEBPp (i.e. savings above and beyond what would have occurred without the programme).

1999/00 results show the Programme has achieved cumulative savings of �M/year (1990 prices), 116 PJ/year primary energy (against a target 105 PJ/year) and 1.8 million tonnes of carbon. Results are stratified according to building sector and by region.
