B. Project description Aquitaine Bordeaux Campus Created through the symbiosis between man and environment, our design project aims to be a sustainable house, which can be modulated according to everyone needs. We focused on energetic performance, bioclimatism, innovative engineering systems and a great management of resources like energy and water. 1. Sustainability The energetic performance is acquired by associating bioclimatic principles: great insulation, green materials, natural ventilation, solar protection... and engineering systems: phase change materials, solar panels or concentrator. Collecting rainwater and recycling grey waters through a vermi-filtration to reuse them in the house participates to a great water management. Savings and responsible consumptions of water and energy lead to an autonomous house. The materials are chosen after the evaluation of their life cycle analysis. Moreover, using local materials, as timber, reduces the transport and so on the costs and helps to maintain and support local factories. It also participates to a low environmental footprint. 2. Bioclimatic concepts We focused on a few bioclimatic principles, as ventilation, solar strategies and great waste and water management. In this project we cannot use the ground's inertial mass, so we have to be really efficient on ventilation and solar strategies in order to achieve great comfort conditions. Solar strategies Winter: the house captures free calories through glass panels (greenhouse effect) on the south side, warms up, and therefore it reduces the house heating needs. We use inertial materials, which stock the heat, then diffuse it later. Summer: the second skin protects the house from the sunrays, and during the night, we create an over-ventilation to cool down the entire building. 7
Ventilation We use a system of natural ventilation through the house, by thermal draught. The heated air flows up due to the difference in temperature and density, and exits through superior windows. We also add a heat-exchanger ventilator, a simple device that keeps heat in while moving stale air out in winter, or cooling down the incoming air in summer. At the back of the house, on the North side, we have set up a system to regulate the winds: a few swivel blades, going from the ground to the roof. 3. Architectural Design These bioclimatic strategies lead us to a specific design for the house. For instance the roof's sloped form comes from the concept of thermal draught, as this form would reinforce the natural movement of heated air. Also the house spreads towards the South through the second skin to provide in summer a great protected exterior space, which is adapted to this climate's lifestyle. On the other hand, on the North side the house is mainly closed, as the glass surfaces lead to major heat loss. There only are a few openings in the thermal envelop, leading to a small exterior area, to enjoy a shady place during the hot summer days. 4. Modularity The house can be adjustable according to the seasons, the time of the day, and the inhabitants' needs: from a single family house, we can develop a large area to welcome several people. Most of the furniture are put away in the walls, to release a larger interior space. This space is not frozen; we can squeeze or expand it, in all possible dimensions allowing several combinations. This living house is also related to nature, as changes can occur in the envelop, through moveable elements, allowing more or less contact and continuity with the exterior. Also, a second skin creates an additional space, an intermediate area between the private house, and the exterior space. 8
5. Comfort A well insulated building, linked with natural ventilation and a great hygrothermal management would provide a correct level of comfort in the interior space. The sloped shape of the roof, allows the building's envelop to take off so as to bring natural light from the North: a diffuse and homogenous light, favorable to studious, resting and calm activities. We can always modulate the interior space so as to find the best atmosphere, according to our needs: through the furniture, the lighting ambiances. With all these components, we live in harmony with the house and the exterior environment, in real osmosis, and total freedom! 9
