Approach for the Improvement of Energy Performance of a Stock of Buildings

This paper summarizes the work performed by CSTB, ADEME and the Ministry of equipment in France to improve the energy performance of the ministry stock of buildings: 7 millions square meters, 10 000 buildings, wide range of different buildings of different sizes and uses. The project has four major phases: analysis of existing tools for energy performance evaluation, identification of the endusers of the tools and definition of a building typology, development of tools adapted to the endusers, validation and improvement of the tools. Since the building managers' motivation is an important factor to improve the energy performance of the buildings, the study has tried to incorporate the endusers needs and constraints in the different phases of tools development
