The Artificial Sky is an important element of Daylight Laboratory at the Department of Architectural Design, Form and Colour Studies, NTNU, Trondheim. It simulates a totally overcast sky, i.e. overcast enough to prevent perception of the sun and its halo. Among other tasks, the Artificial Sky can be used to perform psychophysical experiments for a number of different purposes. In a current experiment the influence of different window classes in house architecture and the corresponding human colour perception in the room have been investigated.
Aditya Sole and Peter Nussbaum from the Colorlab contributing to the project with conducting objective colour measurement. To determine the colour values colour measurements with the Minolta CS-1000 spectroradiometer of different NCS samples under different window class conditions have been taken.
For more information regarding the project please contact Professor Barbara Matusiak, Head of Department of Architectural Design, Form and Colour Studies, Faculty of Architecture and Fine Art, NTNU, (barbara.matusiak@ntnu.no).
