Article
Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in archit...

Project
In this research, novel solutions are proposed to solve the problem of excessive heat gain through atria by integrating the top layer with semi-transparent photovoltaics system to shade the atria and convert the incoming solar radiation into electrical energy instead of thermal energy. The PV layer heated by absorbing incoming radiation will be cooled by different configurations which could remove/reduce heat gain into buildings and in the meantime enhance performance of PV.
