APLICACIÓN DE UNA METODOLOGÍA DE DISEÑO ANALÍTICA, SINÉRGICA Y ADAPTATIVA PARA EL DISEÑO DE NZEB (EECN): MEDIDAS PASIVAS

Abstract

In response to the paradigm changes in the energetic models a significant improvement in nearly Zero Energy Building (nZEB) design have been achieved, partially because, as stated by the European directives, it will be soon compulsory for new buildings. The reduction of the energetic needs following a passive model should be the starting point of nZEB. Although a number of studies have been carried out taking it into account, those concerning the Mediterranean weather are few. So a design methodology following the nZEB paradigm has been applied to a new building, a detached family house, in that region. The energetic optimization of that building requires analyzing different isolated parameters and categories by means of computer simulations in order to find out their effect in the thermal energy demand. They should be dynamically calculated based on an hourly base (UNE-EN ISO 13790:2011) carried out with Cypecad MEP. To do that the behavior of different elements of the building are simulated: house facing, frontage, dividing walls, partition walls, walls in contact with non-habitable areas or the ground, surfaces in contact with the ground, covers and roof, windows, skylights and openings, use profiles, heat recovery in ventilation, etc.
