Celebrating light


Daylighting Strategies Implemented

Figure A: Schematic Section showing the daylighting strategies employed.

Figure C: Small punched openings positioned high along mainstreet allow direct sunlight into non-critical task areas and the resulting light and shadow create movement and interest. The openings are beveled to optimize light and minimize uncomfortable contrasts between window and wall.

Figure D: The condition at the new and existing building interface presents an opportunity to create clerestrories at the high-low roof intersection. The clerestory on the left faces north and brings in soft diffuse light while the clerestory on the right faces west.

Figure E: Existing clerestories in the renovated portion of the regional center were retained and re-glazed with new higher performance glazing for improved daylighting performance. They allow daylight in the areas of the building core that would otherwise be windowless.

Figure B: Prismatic glass redirects intense rays of light coming from the West up onto the plaster scoop.


Daylighting Strategies Implemented

Figure 1: Shafts of daylight stream into West Rotunda Interior providing a feeling of well-being as well as valuable information.

Figure 2: High clerestories in the library at”Mainstreet” provide glare free abundant light to the room below without the problems of direct light. The vertical surfaces bounce and diffuse the light

Figure 3: Sloping the ceiling has the same effect as maintaining the higher level throughout the space with the added advantages of greater clearance above the ceiling for mechanical systems where it is needed and the ceiling is brighter than it would be if flat because it reflects incident horizontal light much better.

Figure 4: A highly efficient reflective film called SOLF (short for solar optic lens film) made by 3M, optimizes the effectiveness of these light shelves in the Library which bounce light up onto the sloped ceiling providing more even illumination in the space. They also reduce glare near the windows

Figure 5: By providing a graduated “frit” pattern on the glass above the light shelf instead of using the solar shade, we ensure that there will always be illumination for the light shelf and the frit reduces heat gains similar to the shade system but with far less cost.

Figure 6: The molded plaster light “Scoop” in the Courts waiting area effectively softens and distributes light not only to this space but the adjacent rooms as well.
