Design optimization of a solar system integrated double-skin façade for a clustered housing unit

The study compares a conventional double façade (DF), a building-integrated photovoltaic double façade (BIPV DF), and building-integrated photovoltaic thermal double façade (BIPVT DF), by considering the impact of the depth of the cavity between the photovoltaic system and the façade. The problematization aims at augmenting the function of an interstitial spaces between building envelope and programmed space both in terms of spatial expansion, but also in terms of energy production. The approach involves examining this space in terms of its spatial parameters and ability to accept an architecturally integrated solar system.
