For humans, architecture is a shelter for dwelling. People seek protection and a sense of belonging in their surroundings. Architecture should reveal the time passage, changes in weather and the character of the place in order to make a place for people to dwell. Sunlight, as an abstraction of the sun, can be received by architecture and connect the place with the universe. This thesis explores how to apply sunlight research as a meaningful tool in architecture design. The research focused on two criteria: orientation and identity. Orientation and identity are the two elements that make a location into a place and make a space into a room.
