Inner yard building occupant’s perception versus the computer simulated metrics of daylight : Field study and simulation-based analysis of inner yard building

Sammanfattning: This Master thesis was aimed at investigating common daylight evaluation methods related to Swedish building codes versus human perception of daylight in residential spaces. Field (interview) and simulation-based study were conducted in one of the typical 20thcentury residential, closed courtyard buildings in Stockholm.   12 residents of Kv. Väktaren 16 were interviewed and simulation models were prepared for the apartments occupied by the participants.   Resident perception of light was mostly contrary to daylight assessing values and methods of daylight factor – DF in a point (CIE overcast sky) and alternative method of window to floor area ratio – AF that are stated in Swedish standard (Boverkets byggregler BFS 2016:6).    Attractive and interesting view, access to direct sunlight and visual comfort played important role in overall occupant satisfaction level, this suggests that daylight metrics should include perception-based factors, which positively impact our health and well-being.
