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.
Today, the building sector represents 44% of the energy consumed in France, far ahead of transportation, which makes it one of the key areas in the fight against global warming and invite the community to the energy transition. The shape, now is just a factor that is considered only aesthetically and not for its energy impact. The objective consumption of the various surfaces of the living space plays a crucial role in encouraging the energy transition in the building and civil engineering sector. In addition, the shape of the building as a whole, as well as the interior design, and the distribution of spaces have a significant influence on energy efficiency [1]. Our contribution in this paper is to make a numerical analysis of the impact of a building conception on its energy bill, more precisely, the influence of the geometry resulting from the assembly of these containers as well as their layout, and their orientations. The container represents a unit that is part of a complex and multiple systems, which offers a new opportunity for architects to rethink their designs both in terms of aesthetics and impact on the skyline as well as in the use of innovative, environmentally friendly and sustainable materials. In this paper we will focus on a purely formal analysis first with TRNSYS, and then we will start with an elementary modelling meeting the criteria of sustainability (eco-container), in those to lead to a design that is economical and energy efficient.
