Architectural repertoire and daylight metrics

• With this article wehighlight the importance of architectural repertoire, methods and tools touncover basic components set by building science in performance-basedregulation. This article elucidates the potential of architecturally groundedmethods when assessing daylight often used in legislation and certificationschemes, by making the daylight factor metric intelligible through geometry. Theempirical material used is five architectural cases from 1917 to 2016. Thesefive cases originate from an exhibition room on daylight presented in relationto architectural composition, historical changes in Swedish building regulationand the 2014 daylight factor building code requirement. The Swedish buildingregulation has, as many other countries, undergone a historical change fromprescriptive-based regulation to performance-based regulation. With regards toregulating daylight this has meant replacing requirements based on geometricalrelationships with abstract building science metrics. Additionally,we review these findings in relation findings from a numerical analysis of 2014daylight factor building code requirement from a larger number of Swedishresidential building stock from the 20th century. This articleargues that architectural research based in drawings and geometricalrelationships and case study material, weather historical or contemporary, canguide practitioners towards a new understanding of building code.
