Hybrid Solar Systems in Buildings: Two Case Histories

摘要

The utilization of Hybrid Solar Systems in buildings allowed a rational use of energy required to obtain proper comfort conditions inside the building itself. During some research programmes carried out at ICITE, prototypes of test cells capable of supplying significant information on the energetic behaviour of technologically innovative building envelopes for passive and hybrid solar control, have been designed and built. Using these test cells several studies have been carried out on different systems and components; two of these have been pefected; an opaque multilayer system and a ventilated dynamic window. Afterwards, it was believed onvenient to rely on a practival tool to be used to assess the different systems' typologies under different working and climatic configuations. This is the reason why a mathematical model was studied, optimized and valideted on the basis of data obtained from experimentation carried out in real working conditions on the opaque multilayer system and on the ventilated dynamic window. The paper presents the analysis and optimization of two solar systems from an energy point of view, y using a finite element simulation model.
