Blood and Tissues Bank of Catalonia


The project, in short

The Blood and Tissue Bank (BTB) is conceived as a large box of white concrete, made up of the façade and four interior nuclei that incorporate building services and access, allowing the building to adapt to any technological and organisational changes. The design of the building paid special attention to energy demand reduction, highly energy efficient equipment, integration of solar thermal and photovoltaic systems, improvements in terms of health and comfort and water saving.

The thick façade, altogether with high levels of thermal insulation, act as an exterior shield against overheating. Less than 50% of the façade is glazed and selective glazing has been used. Interior blinds with mirrored horizontal laminas transport the daylight further into the building reducing the demand for electrical lighting. The air conditioning equipment allows free cooling and 100% heat recovery during renovation of air in the building. As a result of these design measures, the thermal demand of the offices has been reduced to 8kWh/m2 for heating and 24kWh/m2 for cooling.

The heating and cooling system is based on the use of centrifugal compressors with floating turbines, condensed by highly energy efficient adiabatic chillers.

The sum of these strategies has enabled the BTB building to obtain an “A” grade Energy Efficiency Certification with an overall yearly HVAC saving of 72.12% (1,446 MWh) compared to a conventional building. The additional investment of 1 Million Euros (M€) in a total budget of 29M€, results in an annual saving of 0.25M€.
