1. Most Important Goals

- Building a house of ecological and bioclimatic high, low budget.

- Integration of thermal mass in the basement with the pool water in order to increase the capacity for self-refresh housing.

- Designing a home that can be completely industrialized, and most of its components can be prefabricated.

- Demonstrate that the heating system more economical and effective for a bioclimatic house is based on electric radiators, night rate.

2. Architectural Solution

In order to increase the form factor, and reduce heat gains of housing, housing is a compact volume, perfectly square. Similarly, has a courtyard, two-story attached to the south facade.

Thus, in winter it is open all the shading of the south facade and the house is heated by direct sunlight. The central courtyard acts here as a large greenhouse that keeps the temperature inside the housing.


In contrast, in summer, sunscreens closes all of the south facade (except for the top of the greenhouse), so that housing is not heated, and lit by indirect sunlight from the north, and the top of the Central Conservatory.
