This paper presents selected results from the first stage of DAYKE (Daylight Knowledge in Europe), a 3-phase project that investigates the knowledge on daylighting in buildings among architecture students and practitioners across Europe. Subjective judgements from 561 students from 8 architecture universities in the EU, collected through two surveys in 2018. The key findings are: (i) the spatial distribution of comfort and mood in the classrooms varied depending on sky conditions and distance from windows; (ii) the average daylight factor DF_m showed a good agreement with subjective judgements on the amount of daylight in a space; (iii) experts and non-experts provided similar judgements on the perception of a daylit environment; (iv) a general lack of knowledge about daylighting metrics, regulations, assessment tools and software was highlighted. Furthermore a difficulty in implementing daylighting into the design practice is also identified.

Two independent surveys were conducted in 2017 and in 2018 among architecture students across Europe to investigate their knowledge on daylighting and the impact of that knowledge on the visual perception of daylit spaces. A total of 600 responders were involved. This paper presents findings from the second survey, which was distributed in six European countries. Based on the findings from the first survey, a new goal was set for the second survey: to examine how daylighting knowledge may influence the visual perception of it and how the perception of a daylit space by a student population and by experts compare to each other. Three main findings were observed: i) the perceived comfort shows a better agreement with mood than with sky condition; ii) the judgments expressed by the experts and by non-experts are consistent with each other, confirming an outcome of the earlier study and iii) there is a lack of knowledge about daylighting metrics and regulations as well as a difficulty in implementing daylighting into the design process. These outcomes highlight the relevance of reconsidering the way daylighting education is delivered in current architectural programmes.@en

DAYKE (Daylighting Knowledge in Europe) is a project to investigate the daylighting knowledge and skills of Architecture students and practitioners from different countries within the European Union. This paper introduces the first stage of the research and provides results from a direct survey taken by 161 students from seven schools of Architecture: two in Italy, one in The Netherlands, two in Poland and two in Spain. The results indicate significant national differences in preference and perception of daylit spaces. They also show a lack of knowledge about daylighting metrics and regulations among the respondents. Although the research is undergoing, the preliminary data analysis indicates that there is a need for enhancing the daylight knowledge among future architects.@en
