Weighting variables for building performance evaluation

Abstract

Building performance appraisal needs to be done as a form of evaluation, so that the level of usability of a building can be seen at the operation and maintenance stages. The purpose of this study is to give weight to the variables used in evaluating the performance of a building. In this study, the identification of building performance variables is based on literature studies and semi-structured interviews from the experts of the field. The determined variables are then filtered using the Relative Important Index (RII) method, and weighted using the Pairwise Comparison method. All this process is conducted based on the opinion of experts who are competent in the field of building, and all stages are conducted by questionnaire. The results of the filtering and weighting of variables produce 5 (five) variables and 24 (twenty four) sub-variables used in building performance evaluation, with the results of weighting for safety variable with a weight of 59.2%, health variable with a weight of 24.6%, comfort variable with a weight of 10.2%, ease variable with a weight of 4.3%, and utility variable with a weight of 1.8%.
