Étude de l'éfficacité énergétique d'un bâtiment d'habitation à l'aide du logiciel de simulation DOE-2E

The goal of this Master's thesis is to investigate the methods used for estimating energy consumption in housing. The capacity to predict the energy consumption is very useful during all steps of the life of a building. In new constructions, the prediction of energetic costs associated with various options of conception can help owners and builders to make the best decisions in terms of energy efficiency. Similarly, the modelling of energy consumption of existing buildings allows the establishment of an energy-saving strategy to act efficiently on the most energy-consuming elements.

The use in this study of the DOE-2E software as well as its interface EE4 has allowed the creation of a model of existing building to simulate its energy consumption. The studied case is validated on the basis of a comparison between the results estimated by the calculation software and the energy really consumed. This model will be useful as a basis for the evaluation of the energy used in buildings under construction and in existing buildings. At the end of this analysis, a study of sensitive parameters is carried out, proving an illustration of the essential elements that can easily modify energy consumption. An intervention in the right direction on these elements proves itself very useful energy-wise.
