JANE'S BEDROOM (Modified)

Silvia Guimaraes, Jane Lin, and Karen Carrier

Exercise 1:

Comparing a physical model to the real world. 

The Model Compared to the Real Space
The real space chosen was Jane's bedroom that has windows facing south into a garden. We went through two sessions of model testing and modification, the first with little success, and the second with great improvement. Here are the results from the second test:

The Space as Originally Configured
- Plans and Elevations showing isolux contours of footcandles under cloudy sky conditions.
- Plan (and section) drawings showing isolux contours of the model's daylight factors for a cloudy day.
- Daylighting Data

The Modified Space
- Plans and Elevations showing isolux contours of footcandles under cloudy sky conditions.
- Plan (and section) drawings showing isolux contours of the model's daylight factors for a cloudy day.
- Daylighting Data

The Modified Space

Modified Model Space
Our intentions were to wash the ceiling and side walls to bring daylight in as far and as evenly as possible. The contrast between the bright windows and the wall is the biggest drawback to this scheme, but on the whole the room's light levels did improve.
