Toward Architectural Design Method for Coloured FaÇade Integrated Photovoltaics, an Example from the Nordic Context
Abstract
Façade integrated photovoltaics (FIPV) is a strategy to deploy solar energy systems in built environment, especially for high-rise buildings having large façade areas. However, many of the new FIPV are not liked by people cause black colour; there is growing demand 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) serve as cases for the study. The methodology consists of three steps. In the first one, the façade colour strategies are developed referring to the colour design guidance of Trondheim and analysis of the local colour context. Then, the solar potential of building envelope is analysed in Diva for Rhino, façade areas are categorized according to solar harvest potential. Finally, façade designs are proposed for the towers; energy productivity is also calculated. From 28% to more than 35% annual household energy consumption could be covered by electricity produced by FIPVs.
