IB-S – Institute of Science And Innovation for Bio-Sustainability, Minho University, Braga, Portugal.
The project won the competition for the development of a building for the University of Minho, Braga in Gualtar, for the Institute of Science and Innovation for Bio-sustainability.
The building is easy to understand visually and spatially perceived, being composed of a central atrium that distributes to two intertwined stairs creating a vertical spiral culminating in a zenith lighting point that illuminates the entire central space. In this sense, the main structure is composed of the central core of the building on which each floor is supported and developed. The successive use of staggered floors reduces the use of structural elements, without reducing structural performance, achieving architectural and spatial freedom. In coordination between Architecture and Natural Ventilation Systems, the use of hollow slabs allows the admission of air from the facade to the interior patio, taking advantage of the thermal inertia of the structure to cool during the night.
The project proposes an innovative facade system. Protection from direct sunlight is guaranteed during any light orientation at any time on any day of the year. Natural light is used to its fullest potential, reducing costs. All interior spaces have a light sensor that dims artificial lighting when natural light is available.
