1. Most Important Goals

- Designing a home-budget semi-buried, and integrated into the natural environment.

- Dumping the house around the pool, so that you can access it from any room.

2. Architectural Solution

Without doubt, this is the lowest bioclimatic housing all analyzed, but it is interesting to show to show, that a sensible architectural design, can improve the performance of bioclimatic housing, despite the contrary requirements of an owner. When the architectural style of a building is not correct, there is little that can be done. However, there are so many decisions that an architect can take, regardless of the demands of the owner, the end result may be satisfactory.

Initially presented to the owner a higher level design of a bioclimatic, with a more rational type, according to the environment. However, the cultural inertia of the owner and the expression of personal desires (the owner, Mexican, wanted to make a living "Mexican" in a neighborhood of Valencia) led to the proposal.


However, the fact that housing has been partially buried (due to the terrain), and were able to increase the thermal inertia and insulation, has yielded satisfactory results, although very far from what Luis Garrido is accustomed to getting.

The architectural style follows the owner's desire that all rooms of the house have views to the north (at a golf course), and have access to the central pool.

3. Sustainable Analysis

The sustainable features of the House Villazón are identical to Seve House, or House Guaita.

4. Bioclimatic characteristics

1.1. Heat Generation Systems
By decision of the owner, the house has no bioclimatic system (architecture) for generation of heat. However, have been minimized to the maximum energy requirements in winter, because of high insulation, high thermal inertia, and the fact that housing is semi-buried. Thus, heating needs are minimal.

On the other hand, has been installed in the home heating system underfloor, heated water-based through solar collectors.

1.2. Fresh Generation Systems
By decision of the owner, nor any system is installed fresh generation. However, the mild microclimate of the environment, north facing housing, proper insulation, high thermal inertia, and the fact that housing is semi-entrrada, makes the interior temperature is sufficiently low, as not to need mechanical cooling air.

3. Storage systems (heat or cool)
The heat generated during the day in winter it accumulates in the floors and load-bearing walls, keeping the house warm during the night. Similarly, generated during the cool summer night up in the floors and load-bearing walls, keeping the house cool during the day. The roof garden high thermal inertia, reinforces this process.

4. Transfer systems (heat or cool).
The only heat transfer by radiation is used. The accumulated heat or cool the interior load-bearing walls, is transferred by radiation to surrounding rooms.

5. Natural ventilation
The ventilation of the building is a continuous and natural, through the very walls surround, allowing adequate ventilation without energy loss. This type of ventilation is possible as all materials are breathable, although the whole performance has a completely waterproof.

5. Organic materials

We used the same materials as in the House Seve.
