Building Description Building has an expansive, square floor plan. All four sides of the building possess windows, allowing the invitation of natural light.
However, each side has different conditions and characteristics of how natural light enters. South facing windows receive direct sunlight, whereas north facing windows are mostly exposed to reflected light from adjacent buildings.

North Facing Area & Neighboring Buildings
Impression of the Architecture
The first impression of the Rockefeller Library was the diverse influence of light into the different floors and orientation. Expectation: South
Glaring / North however...
Relatively darker
The lower floors had drastically different lighting conditions due to the reflective light from the neighboring building on the North side. In result, the Ground floor and Second floor’s north space is brightened by the reflection of white facades, with signs of excessiveness.
Key Question
How can we manipulate the reflected natural sunlight coming into the North faรงade to be less glaring and more comfortable for the occupants sitting in the line of carrels against the North windows?
Problem 1. Natural light does not propagate all the way into the space 2. Narrow alleyway = disruption to study desks 3. Glare (from reflected light) = discomfort to study desks
Proposal 1. Light Shelf
2. Extruded Space
3. Curved Wall w/ vertical shades angled at 30° (for view)
Proposal 1. Light Shelf -
block glare hitting down from above bring natural light deeper into space
Proposal 2. -
Extruded Space increase more surface area of wall for invitation of light isolating from the extruded spaces & create private spaces. Lounge and outdoor space usage
Proposal 3. -
Curved Wall with vertical shades angled at 30° (for view) block reflected glare hitting from sitting eye-level & from below maintain access to view through glass wall (vertical shades)

Simulation and Data
Conclusion
Existing Issues: 1) 2)
Less daylight into the space Glare problem from neighboring buildings
Design Solution 1)
Further Approaches: 1) Explore material for curved glass wall to enhance its performance. 2) Apply same idea to other facades and explore
2) 3)
Extrude space to outside overhang and remove walls Install vertical shadings Add reflective light shelf and use curved glass wall
