Étude de l'écoconception de maisons à énergie positive

Abstract : The planned generalisation of Plus Energy Buildings constitutes an important topic for sustainable development, especially in a long term vision. However, designing such buildings at lower environmental impact and with competitive cost for the market constitutes a complex issue for the sector’s professionals. This thesis focused on the development of a methodology providing an operational and robust decision support to eco-design plus-energy houses. Based on multi-criteria optimisation (via a genetic algorithm), the proposed approach combines in a multi-tools platform, dynamic building energy simulation, life cycle assessment, and cost construction functions, in order to identify, on a multi-criteria (Pareto front) and life cycle basis, efficient plus-energy houses concepts and to provide decision maker a description of the best compromises. Also included in the platform, sensitivity and uncertainty analysis methods offer the possibility to select the most influent design variables before optimisation, and to evaluate the non-robustness risk of a decision after optimisation, especially regarding uncertainties on occupants’ behaviour (with a stochastic model of occupancy) and climate’s predictable evolution up to the end of the century. Via collaboration with a constructor, the methodology was applied in real-time throughout a integrated design process of a plus-energy house.
