Développement d'une méthodologie d'assistance au commissionnement des bâtiments à faible consommation d'énergie

Abstract : The low energy buildings know, these latest years, a great interest because of the important role that they play in reducing the greenhouse gas emissions on one hand, and the rise of the combustibles prices, on the other hand. Nevertheless, in many cases, low energy consumption buildings do not achieve the expected performances. This problem is largely due to: 1) the loss of information throughout the building life cycle, 2) the non-regular evaluation of the decisions made by the actors intervening in their conception. The commissioning, as a quality control process, plays an important role in the good progress of the realization process of low energy buildings case. This research aims to develop a methodology to assist the persons responsible of the commissioning in the definition of commissioning plans adapted to their projects. Firstly, we performed a state of art of the low energy consumption buildings realisation that we then confronted, to the reality through an investigation with building actors and a study of real cases. This step allowed us to formulate a hypothesis concerning the necessity of a "progressive" commissioning -adapted to project particularities - and to describe a global methodology of assistance to the low energy consumption buildings realisation that integrates a decision making aid, an information management and a "progressive" commissioning that verify the good realisation of the two first functions. To put this methodology into application, a toolbox was developed. It comprises: 1) a tool named "static" that allows defining a first generic commission plan that satisfies the project characteristics, based on an exhaustive data of commissioning tasks, 2) a tool named "dynamic" based on the probabilities, that allows updating the initial (generic) commissioning plan. This update manages the unexpected events met during the project realization; witch permits the commissioning plan to be more precise. An experimentation of the first tool was done in a real case and applications of the second were done to show their possibilities and their limits. The results show two important points: 1) the interest of having a structured and progressive commissioning plan to verify the quality of low energy consumption buildings realisation and guarantee the achievement of the expected performances, 2) the interest of using a probabilistic tool such as the Bayésien networks to anticipate the drifts and to deal with the unexpected events met throughout the building life cycle. This methodology represents a basis for the development of assistance tools for the definition of commissioning "progressive" plans for the new and the existing, and all the building sectors
