| Summary: | Every year the Indian government is involved in the construction of nearly two million new buildings excluding the tertiary sector. These homes are not only intended primarily to house Indian populations, but the authorities concerned have also placed emphasis on sustainable development, since as all over the world the residential sector is the one that consumes the most energy. Indeed, active and passive strategies to reduce the energy consumption of dwellings have been established and even applied. Among the passive strategies, the global shape of the building, initially specific to modular architecture impacts the aesthetic part of the building but also its energetic bills. The concept of modular architecture is mainly the assembly of identical cells and, in different ways, the overall energy consumption depends on the initial assembly of the cells and therefore on the resulting shape of this assembly. The purpose of this article is to determine the impact of the shape on the energy balance. For this study, the container is the archetype used, in fact the metal box being a standardized, economical and easily transformable product in living space. The complex system resulting from the assembly of several containers offers a new way of thinking about housing from an architectural, economic, aesthetic and energetic point of view. In this article, we will focus on studying the impact of the overall shape of container-type housing on annual energy bill, with the aim of optimizing energy efficiency and achieving an eco-container model that meets international eco-sustainability criteria. The results demonstrate the undeniable correlation between geometric and energy aspects, the latter being mainly related to the internal thermal comfort of the container housing cells.
