This is a research-based project investigating the relation between natural light, space and perception. It is in the format of a book with eight parts based on the observation and analysis of physical models. The spaces created in this book are divided in three parts, general daylight solutions, perceptual light-spaces and purposeful light-spaces. The first part consists of 19 spaces transferred from drawings found in Sunlighting as Formiver for Architecture by William M.C. Lam. The second part contains ten spaces based on perception and in the third part the focus in of function, which is generally divided into more general purposes of 13 models. The analysis I am using is a combination Light-zone(s) described by Merete Madsens and the Visual Terms and Seven Basic Terms by Anders Liljefors, which is a way to analyse perception. Following is an analysis of possible functions and daylight variability, which are then concluded. The spaces and findings are compared and summarised in order to find general strategies for the use of daylight in architecture. This book is meant to be used as a learning tool, a handbook and/or a basis for further investigation of the relation between natural light, space and perception.
