The energy quality of enclosure for housebuilding

If we consider a building as clothing for people living inside, it is possible to change its size without perverting its nature only by applying bioarchitecture and bioclimate principles, as well as all those principles belonging to building system quality control-oriented philosophies improving its intrinsic distinctive features. So, the building structure shall be the first Technological System dealing with design changes. Therefore, the building system will be designed or restructured at low operating costs concerning energy consumption thus optimizing (by means of a proper use of materials, components and building techniques) the energy relationship with the surrounding environment, taking into account local climatic conditions and direct users welfare requirements. All the information gathered can be useful at the project level both to settle proper intervention strategies and to encourage a “system design” of the components to be used, and this is possible only because the building transformability, the specific needs, the efficiency and integrability of the chosen technologies have been previously analysed. This kind of design approach is facilitated by the industrial production techniques evolution which is leading more and more towards techniques allowing the diffusion of the use of “on design” components. The building flexibility of new industrial production - which is able to provide, even if at additional costs, with industrial components having different shapes and dimensions, upon specific request - meets the requirement, that designers showed several times, to calibrate the use of technological sub-components in function of the real requirements of architectural language, morphological conformation and solar captation, which are different according to circumstances. An experimental application carried out at the didactic level on an housebuilding, led to find out requalification technological solutions by an energy point of view taking into account the above mentioned requisites as well as the strengthening of local intrinsic features and of the building system interested in the transformation. The didactic experience, carried out within the Technological and Construction Design Laboratory at the Faculty of Architecture of the Second University of Naples, brought out the importance within the architecture design to realize objects as: sustainable use of natural resources, energy waste reduction and quality of life. In the light of the above considerations, the external environment and the climate (characterized by factors such as: sun, wind, rain, remarkably affecting buildings environmental quality) must become component parts of architectural design. Students have been requested to apply the Performance Analysis to check the environmental and energy functioning of their projects.
