Sammendrag
Façade integrated photovoltaics (FIPV) is a strategy to deploy solar energy systems in buildings and built environments, especially for high-rise buildings having large façade areas. However, many of the new FIPV are not well accepted by people cause their traditional black or dark blue colour; there is growing interest to develop architectural design methods involving coloured FIPV, where both aesthetical and energy aspects are included. This is exactly the aim of this study, three high-rise apartment towers in Trondheim (Norway) served as case studies. The methodology consisted of three steps. In the first step, the façade colour strategies were developed referring to the colour design guidance of Trondheim and the analysis of the local colour context was performed. Then, the solar potential of building envelope was analysed in ClimateStudio, façade areas were categorized according to solar harvest potential. Finally, façade designs were proposed for the towers and preliminary rough energy generation was also performed. The outcomes indicated that between 29% to more than 40% annual household energy consumption can be covered by electricity produced from coloured FIPV.
