摘要
In the search for façade solutions that meet requirements for energy efficiency and office space use comfort,it seems promising to apply a combination of photovoltaic(PV)technology with switchable glazing.It is believed that the merging of these two technologies might benefit the cooperation between regulated solar protection and energy efficiency.This article provides a design outlook on the use of PV-EC,PV-SPD,and PV-LCD technologies in terms of their utility for office buildings in moderate climates.This study concerns thermal,optical-visual,energetic,and technical issues,and a comparative method was applied.Based on current scientific research,the results of the analysis were juxtaposed with the requirements of the office working environment:natural lighting,thermal protection,glare protection,privacy control,energy efficiency,and technical reliability.The juxtaposition of these aspects revealed the advantages and disadvantages of a given solution from an architectural point of view.PV-EC technology in a side-by-side system was found to be the most appropriate solution and the results may be applied to make preliminary design decisions.
