Project 3---Lighting (Ceiling) Design

The most challenging design is the "courtyard" in gallery space, it is defined as a courtyard without walls. In the courtyard will be shown aboriginal sculptures which suitable to display under northern diffuse light. But how to achieve this? How to avoid the northern light interfering with southern light?

Requirements:

1.Northern diffuse light for sculpture courtyard
2.Southern light for paintings hung on the walls
3.Two directions light won't interfer each other


My start point is this grid system, it reminds me to use the changable height of the ceiling.




I made a rough model to test the lighting effect

By extending the ceilings around the courtyard lower, the northern light will be diffused and gather to the central area.

The effect of the rough model, the contrast between light and dark can be noticed. The northern light can be the boundaries of the courtyard instead of walls.

The image shows the theory of the ceiling design. The ceiling are approximately 1 meter high, therefore, enough depth could be used to diffuse northern light. The boundary ceiling is much longer preventing northern light diffuse out of the courtyard.

Physical model of the ceiling of the central courtyard.

The combination of the northern light and southern light.

The sculptures in the central are lit by the northern diffuse light, southern light illuminates the paintings. They can exist harmoniously. Meanwhile, the darkness areas between the two light sources make contrast with them.
