The new building, part of Nestlés social block at the Granero factory (VI Región – Chile), uses a variety of bioclimatic strategies, within a company policy of rational use of energy resources and economics in the 21th century. These strategies favorite the usage of natural resources, passive ventilation systems, air-condition and cleaning for inside spaces, natural controlled illumination, effective cost savings in the use of hydrological resources (water consumption of restrooms, etc), by trend to find the best sustainability, quality of life, rational use of resources and protection of the environment.
The building engender the image of a living organism, which changes its tonality (orange ocher, brown) in time and furthermore by the different angle of the sunbeams and changing daylight. It contrasts with the insight concrete walls and the black metal of the cladding. The rhythm of the designed standard-sheets and the perforation type of the panels, are giving different textures and break the monotony of the plane suspended surface, which had been strategically illuminated to strengthen the night image of the building.
The program contemplates a three storey building, with different programs: First floor for employees’ facilities (restrooms, dressing room and cafeteria); the administration in the second floor; the third floor includes laborites and an educational room.
Bioclimatic systems: passive ventilations and the use of hydrological resources
The building is crowned by a suspended roof, façades with a double-skin, the additional multiuse water pond serves as fire-water standby and cooling system through evaporation for the sun exposed façades in the hot period.
The double-skin, made out of corten steel, which wraps around the building, create an avant-garde image. Constructed as a continuous surface, it protects against the solar radiation and due to its separation to the building, it creates a vertical Venturi ventilation, supplying temperate air on account of the evaporation of the surrounding pond. This metallic double skin consists out of different perforation treatments, plain sheets and black glass.
The corten steel is a material which oxidates in a short term period, in order to create its own protection, neutralizing its deterioration. It doesn´t require maintenance.
Rational use of water consumption:
We put a special attention to the water consumption of the restrooms and in general. Using high technology devices and designs, with automatic anti-vandal taps, guaranteeing controlled water consumption, we send a strong signal of protecting both, natural resources and economics.
The design, the materials and the image of the building are an additional value, being a reference to the social responsibility politics of Nestlé Chile to the employees, the community and the country.
