U6. Sustainability in architecture. As we talked in Unit 5, one of the factors that is changing architecture is the way in which we’re now committed to caring for the planet. Therefore, the way in which we work and think of architecture and design will change too. HEALTHY BUILDINGS We’ll deign buildings that will make a connection between human biology and the environment. Therefore, buildings will be designed in order to provide air quality, water quality, natural light and thermal and noise insulation. If this conditions are not fulfilled, buildings can have some symptoms such as moss appearance or even more symbolical ones such as a bad spatial organization. Another important factor is to make sustainable designs: BIO-Architecture It aims to minimize the negative impacts of constructions both on the health of the occupants and on the environment. Bioclimatic Architecture It represents a working method which, starting with preliminary studies of the climatic conditions of the site, directs the project to achieve sustainability and bio-architecture objectives. Constructive Solutions The control of the micro-climate in the different seasons can be achieved through active systems or rather with passive measures, and therefore sustainable, as simple as: hindering direct solar irradiation through windows, adequate orientation of the building, type of building favoring natural cross-ventilation, use of clear finishes to promote maximum reflection or thermal inertia of the building. Materials This is also an important thing to consider, the use of materials whose fabrication is not sustainable, «natural» materials such as wood or materials that need a shipping is an awful idea both economically and sustainably. For this reason, is needed to make a change and start building with local products whose manufacture does not pollute.
