Description and technologies

The main features and technologies used in the construction of the bioclimatic building are listed below. The building is projected to have two floors with approximately 400 m2 each, and a 300 m2 cellar. Laboratories and office rooms will be oriented to the south, whereas rooms of general use (like bathrooms, meeting rooms, conference room…) will face North. The building shape is rectangular and its main facade will be oriented to the South.

Figures 1 and 2 show some views of the building as it will definitively look.

The concrete technologies involved are the following:

• Construction according to the local climate parameters of Badajoz.

• Monitoring of energy fluxes and of wind, as well as installation of human presence detectors, in order to achieve an automatic operation to control such fluxes.

• Application of the specific concepts concerning passive solar heating. Use of Trombe walls. Ventilation of South facade by installing photovoltaic panels. Avoid direct solar radiation into the building during the summer (and vice versa during the winter).

• Efficient thermal insulation, avoiding thermal bridging.

• Window and cover shadowing.

• Natural lighting, combined with high efficiency artificial support lighting.

• Mixed solar-biomass acclimatisation. Installation of approximately 70 m2 high efficiency solar surface collectors using a biomass boiler (pellets), which will serve as energy supply to a cooling absorption engine.

• Full monitoring of the building.

• Real time data transfer to the internet.

The most innovative techniques will be applied in order to ensure the bioclimatic behaviour of the building, the installation of efficient insulation and the use of renewable energy sources. The specific actions concerning each of the technical aspects are described in next subsections:
