Abstract

This research aims at realising a shutter prototype which would allow the containment of the summer heating load in non-residential buildings.With its positioning at the height of the envisaged holes and its particular geometrical shape, this prototype will replace the standard vertical shutter with one containing a glassblock with a sharp inclination with respect to the incidence of sun rays in the summer time. A measurement campaign is envisaged in order to optimize the glass inclination with respect to the incidence of sun rays both during the winter and summer time and the width of the horizontal anti-dazzle screen placed at the top of the shutter. The lack of mobile or steady anti-dazzle screens ensures a perfect view of the external surroundings; in addition to this, the standard levels envisaged for by the existing regulations on natural lighting on the back wall will not be altered. The aim of this work is that of providing a passive element which could concretely guarantee a high level of acoustic and visual comfort, and a proper ventilation in indoor non-residential environments. Keywords: shutter, heating load, acoustic and visual comfort. 1 Introduction This study is about the widening of a particular augmentation system of energetic efficiency in thermal area, by the creation of a building component that can be reproduced in series and integrated in the realization of buildings for nonresidential use.
