The T-House is an architectural response to the daily life needs of a family. The building needs to comply not only with the required program, but also with specific urban regulations and budget limitations. In addition, the client is highly concerned about energy consumption, therefore the architectural proposal has to perform as a passive building through the adoption of a series of different passive strategies.
In first place, the program adapts to the needs of a four-member family with two young children in a suburban area of Madrid. The floor plan is developed in one level above ground with a multifunctional room on top, generated by the geometry of the roof. It contains a living space and a kitchen, which can work together as a one space only, four rooms, two bathrooms and a garage.
The volume is generated by the solar geometry. A series of voids and windows are oriented in a way that direct solar radiation can help to raise indoor temperatures in winter. This geometry also ensures that during the summer periods solar radiation is blocked, avoiding overheating. The triangular roof is the geometrical answer to an orientation adaptive roof.
The house is designed to save energy through the adoption of three main passive strategies: direct solar heating during the cold periods; self-shadowing geometry and nighttime cooling during the summer periods; and an intensive use of insulation and avoidance of thermal bridges to decouple from the outdoor conditions. In addition, solar panels are installed in order to heat up the water.
