In addition to La Fàbrica del Sol, Barcelona has several sustainable buildings. Among them we emphasize:
The building that houses the Blood and Tissues Bank of Catalonia headquarter, located in 22@ technological district is considered an example of sustainable construction and stands out for its great energetic efficiency. The free cooling air conditioners and the incorporation of heat exchangers allow reducing the thermal demand of the offices. Moreover, the wall of façade and the system of thermal isolation act as a shield stopping the overheating. Thanks to these strategies, an important saving has been achieved:
-The building saves the 72% of the energetic consumption of air conditioning (84% of the cold production) regarding what would require a conventional building from the same use.
-It saves almost a million and a half of annual kWh.
-The reduction in emissions of CO2 is about 963 Tm annual.
These reductions mean an annual saving of more of 250.000€.
The Media – Tic building, located also in 22@ district, is another exceptional example of sustainable and quality architecture. Created by the architect Enric Ruiz – Geli, this construction only use renewable energies.
One of the strong points of the building is the climate regulation, which is carried out by the original façade where are located some sensors called “luxometres” and an innovative material known as Teflon, which acts as a solar filter. The façade optimize the solar light to create an appropriate climate atmosphere insight the building. This fact allows saving the 60% of CO2 emissions because the use of heating and air conditioning diminish visibly. The façade and other elements of the building as the solar plaques from the terrace allow a reduction of 20% in energy.
Is interesting to know that the construction cost of sustainable buildings is not superior that of other buildings. So, sustainable construction has many advantages and makes us move forward towards a friendly – environment future.
The Baró de Viver Civic Center is the first sociocultural equipment in Spain to obtain the LEED Platinium certificate, the highest award for the sustainability of buildings at an international level. This civic center has a plant cover that collects and filters rainwater, photovoltaic solar panels and lots of natural light. In addition, the thermal and acoustic insulation of the building has been made using the natural characteristics of rock wool, which in turn has contributed to increase the safety and durability of the same.
