ABSTRACT
For several years now, there has been an increase in the number of contracts for the construction, renovation, operation and maintenance of buildings including energy performance contracting (EPC). An observatory has been recently created for energy performance contracts that allows feedback analysis. The first experiments were carried out by public authorities, particularly on projects for the construction or renovation of school buildings. The success of this type of project also depends on the balance of the relationship between the co-contractors. To this end, the client must have the necessary skills to frame the process and all the parties must be willing to progress together towards the energy performance objectives. Standards such as the International Performance Measurement and Verification Protocol (IMPVP) also aim to support and standardise energy performance guarantee projects. The majority of the contracts currently implemented the renovations of existing buildings or new buildings linked to the public sector. To generalise the processes and to progress towards applying this approach to buildings with very high energy performance, or even positive energy, new methods based on dynamic energy simulation have been developed within the framework of the work by the Eco-design of Buildings and Infrastructures Chair supported by VINCI. The proposed methodology is described below, and an application to a case study is presented.
