Research on BIPV in Office and Public Utility Buildings in Aesthetic and Utility Context

Abstract

The idea of the article is to examine the perception of building-integrated photovoltaics (BIPV) by users of buildings in which BIPV has been applied. The study aims at determining the acceptance degree as well as problem areas related to the use of BIPV within façades in the aesthetic and utility context. The article includes survey research conducted among 232 employees working in six office and public buildings with BIPV in Poland. The buildings were selected so that the PV modules within their façades were visible both outside and inside the building. For this reason, two groups of buildings were chosen for the study: those with PV modules as external glazing and with an external PV shelves (three buildings each). The research results indicate differences in the perception of the aesthetic, semantic, and functional roles of BIPV depending on the aforementioned BIPV application method, the observation place (outside or inside the building), and employee characteristics, i.e., groups divided regarding such aspects as their age and time spent in the room with BIPV. The research novelty is in examining the influence of BIPV on users’ reactions in their workplace in terms of aesthetic and utility issues. The research includes post-occupancy evaluation method (POE), which is for the first time used in relation to BIPV in office and public utility buildings. The research can prove useful for investors and designers at the planning and design concept stage. The outcomes constitute a practical source of knowledge for BIPV manufacturers.
