Interlayer and cavity contribution to creating high light-to-solar-gain-ratio glass block from waste glasses

This paper illustrates the results of the performance analyses conducted on an innovative glass block integrated with thirdgeneration\ud dye-sensitised solar cells (DSCs), designed to enable the construction of translucent and sustainable building\ud envelopes.\ud The analyses include the simulation of both thermal and optical performance with regard to different configurations of\ud the photovoltaic (PV)-integrated glass block, and the results obtained are presented using two different programs:\ud Comsol Multiphysics and WINDOW. The configurations may differ – for example, because of the position of the module\ud inside the glass block, the type of DSC module used (composition, transparency, design) and the features of the glass block\ud itself.\ud Different combinations in terms of thermal insulation, light transmission and estimated PV production are discussed. The\ud position of the DSC module within the glass block has a significant impact on the thermal and electrical performance of the\ud product, but not on its optical behaviour, which instead depends on the type of module used.\ud The aim of the study is to define some optimum combinations according to the different needs of active building facades\ud and requirements related to diversified climate contexts

As a symbol of green architecture, double skin facade (DSF) represents a design which possesses many energy saving features, but due to the complexity of the system, the real performances and benefits have been difficult to predict. The objective of this study was to inform the applicability of DSFs, and contribute to the positive impacts of DSF designs. This study compared and contrasted energy savings in a temperate climate, where heating was the dominant energy strategy, and in a subtropical climate, where cooling spaces was the dominant issue. This paper focused on a university office building with a west facing shaft box window facade. The research method was a paired analysis of simulation studies which compared the energy performance of a set of buildings in two different climates. Simulation results showed a good agreement with measurements undertaken in the exiting building during a two-week period. The results specified that DSFs are capable of almost 50% energy savings in temperate and 16% in subtropical climates. Although these indicated DSFs are more suitable for temperate climates than warmer regions, the amount of energy savings in subtropical climates were also considerable. However, due to the costs of DSFs and potential loss of leasable floor area, investigations into other feasible ventilation options are necessary before final building design decisions are made.
