Abstract

Cooling of buildings: energy efficiency improvement through ventilated structures M. Ciampi, F. Leccese & G. Tuoni Department of Energetics "L. Poggi", Faculty of Engineering, University of Pisa, Italy Abstract Some peculiar cases of ventilated facades, also occurring in conservative recovery interventions of the existing building heritage, are examined. For this purpose the influence of the variation of some environmental and geometrical factors on the energy performance of ventilated facades is investigated. Finally, the advantage of using solar chimneys to enhance air movement in naturallyventilated buildings is examined. 1 Introduction In the last few years the passive solar systems for the cooling of buildings have been made the subject of numerous studies, both theoretical and experimental [I-51, owing to the remarkable reduction in undesirable summer overheating due to direct solar radiation achievable by using these systems. Among the particularly interesting passive solar systems are
