Analysis: the louvers do a good job of shading the building throughout the day, allowing sunlight to enter the atrium and main circulation areas during the morning hours. The rest of the day sunlight is bounced off reflectors and the louvers providing indirect luminance. The views are only moderately obstructed. Views out are enhanced by the louvers on the facades being made of a low-e glass, so there is still transparency, though in different levels of clarity across the bands of louvers and open areas.

ANALYSIS: THE LOUVERS COI\IE STRETCH OUT BOTH DIRECTION OF THE AIRPORT WHICH BLOCKS THE SUN DURING MORNING AND AFTERNOON. THE OPENINGS ON CENTER OF EACH ROOF PROVIDE LIGHT INSIDE BY PLACING REFLECTOR RIGHT BELOW THE OPENING. THE LIGHT SPREAD AND FILL OUT THE CEILING AND TRAVEL THOUGHOUT THE AIRPORT

Conclusion
After a thorough investigation of the selected precedents and the ensuing design, we as a group found our design to be a success. Due to the thickness of the walls coupled with the dimensions of the windows the sunlight is avoided during the summer and welcomed during the winter; while the equinox period of the year is within a comfortable range. However, because of the extreme low altitude of the sun at 5 PM during the summer, western sunlight could not be avoided within the parameters of the design.
