The cost-effectiveness of current building energy audits : A comparison of four commercial audits applied to three different building typesFunded under: JRC-ENREFMET C
In this study, various buildings were investigated using Energy Auditing techniques. The aim of the exercise was to compare commercial auditing methods from the point of view of accuracy and cost- effectiveness. Four different companies carried out energy audits on six blocks of apartments connected to the same heating plant, a primary school and a terraced house. The audits were compared not only with each other, but with the results of a much more detailed benchmark study, carried out by the authors. Large differences were found at all stages of the audits, from such basic data as building dimensions and length of heating season, up to the final recommendations. There was no observable correlation between the degree of detail and cost of an audit and its overall cost-effectiveness. The benchmark study identified a considerable number of potentially cost-effective energy saving measures specific to the buildings audited, which were completely overlooked by the commercial audits. A number of possible improvements to commercial energy audits were identified.
