The SLOW Building Barcelona office building, located in Sant Cugat del Vallés, has become a benchmark in Spain for sustainable and healthy buildings since its inauguration, and it is now a reality.
Designed by the architectural firm Bailo Rull and the building project management company HAUS HEALTHY BUILDINGS, it is considered one of the first nZEB (Nearly Zero Energy Buildings) in which Lamp has provided lighting adapted to the holistic approach that guides the project, which focuses on looking after the environment and people.
Slow Building: How it started
As Ricard Santa María, Managing Director of H.A.U.S. Healthy Buildings, explains, "The first challenge when we sat down to study the characteristics of the place was to propose an urban planning rethink that would help us to achieve the objectives we had in mind in terms of health and sustainability".
In this way, we assessed the impact that this building would have on sustainability, but also on people's well-being and health, and, right from the beginning of the project, an effort was made to observe and understand the existing conditions with respect to:
- Natural lighting.
- An acoustic proximity map.
- The thermal and bioclimatic behaviour of the potential building.
- The quality of the surrounding air.
- The quality of the water supply.
- The physical toxicity of the surroundings.
…and, in this way, the optimal solutions to meet the project's highest objectives were proposed.
SLOW Building: The results
The DGNB certification (the German sustainable building label awarded by the Green Building Council Spain - GBCe), the energy demand A certification, and the creation of an nZEB building all validate the effectiveness of the strategies integrated into the building from an environmental point of view. As a result, the SLOW building will have 25% lower energy consumption compared to similar buildings constructed in the last 5 years.
From the orientation of the building to its design, as well as the materials used, the building makes maximum use of natural resources and minimises the production of waste, always prioritising passive solutions over more active ones, as in the case of the study of orientation and the different treatment of the façades according to thermal efficiency.
-North façade with glazed curtain wall.
-South façade with solar filter panels and operable panels.
-East and west ventilated façades with a perforated sheet metal finish to reduce solar radiation.
Areas designed for people's well-being
As for strategies focused on improving people's well-being and health, various solutions have also been implemented, such as the creation of outdoor areas and spaces intended solely for rest and relaxation. For every 7.2 m² of office space indoors, there is 1 m² of outdoor space.
Beyond ensuring energy efficiency, special attention has been paid to design features that maximise environmental comfort levels, in a comprehensive and holistic manner:
-Acoustic comfort by allowing work in open areas;
-Air quality by facilitating natural cross-ventilation, as well as the incorporation of air renewal systems;
-The treatment of electric fields and waves by absorbing electromagnetic interference;
-Climate management for improved thermal comfort;
-Eliminating environmental toxicity thanks to materials with low VOCs emission, as well as the use of paint with antibacterial and CO2 metabolising properties;
-The building is equipped with water fountains providing ionised, mineralised, and filtered water fountains to offer the best quality water to users;
