Healthy and sustainable solutions require an approaching to the site. The assigned plot provides information to take into account It’s needed to use BIM tools —Revit, Vasari, Ecotect, Flow...— before designing, like the views, the topography, the weather or for the complete design, because nowadays informatic prothe climate. grams can anticipate to most issues related to construction.

House owners: Couple of designers with two children Plot surface: 1000m2 Maximum built surface: 200m2 Needs: 3 bedrooms minimum of 3 bathrooms working place / studio living&dinning room kitchen Other features: swimming pool garden area

The house design starts from the concept of the cave and progressively evolves, through a feedback process of analysis and comparison, into a viewpoint building with a private landscape given by the plot.

Since the most part of the design process relies on the previously mentioned solutions, the project is designed from the perspective of natural —almost traditional— materials, adaptation to the slope and passive strategies like patios or cross ventilation.

Getting into the design of BIM tools implies getting used to the The conceptual masses analysis show energy results, related to workflow of these programs: the behaviour of the building will be the electricity or gas consumption from the construction to the analized during all the project. Because of the power of analytical use of the building. masses, it is possible to know whether or not the solutions proposed work better or not.

Through the BIM tools it’s possible to know which areas will need artificial lightning during the day and which not. They also give information about ventilation through wind streams.

By orienting the building to the southeast, it can be seen that the most part of the rooms are lit by the sunlight. But, in therms of solar radiation, the projections and projected volumes reduce its impact considerably. Also, just by opening several windows the air can flow through the rooms.

Cooler area

Sun radiation remains controlled, since it won’t surpass the medium values in the whole summer.

Sunlight gets into the house mostly from the southeast. The patios located north provide additional natural light.

Darker area

The wind streams may be rearranged by the own user, taking advantage of the cross ventilation from several points.

The open concept of the hose keeps its design simplistic.

The most part of the exterior walls are covered in limestone, but the southern courtyards are covered with black slate stone.

There is white quartzite in the northern patios. On the other side, the north façade is covered with a reddish wood layer. The porche floor is solved with a wooden flooring prepared to support the sun light and the water.
