Exterior Street Entrance: Overview of Space: The street entrance is the main entrance for the members of the community who are entering the library. The purpose of this space is to effectively and aesthetically allow patrons of the library to enter the building. At the same time people are passing in and out of the library, there is an outdoor seating area for the library s café on the Northwest corner of the building. The façade of the building along the entrance is glazing. The steps are concrete and the patio is brick. Existing Area Description: The area is an angle around the North point of the building. It is a wide patio wrapping the façade of the building. Furniture description and layout: There are a dozen tables for the library s café seating area. Page 14 of 57
Design Criteria: IES: Active Exterior Entrance: Very Important: Horizontal: 50 lux Vertical: 30 lux Appearance of Space and Luminaires, Color appearance and contrast, Direct Glare, Light Pollution, Modeling of Faces or Objects, Peripheral Detection, Points of Interest, Reflected Glare, Shadows, Source/Task/Eye Geometry, Surface Characteristics Important: Light Distribution on Surfaces, Sparkle/Desirable Reflected Highlights Evaluation of Criteria: The leading factors that affect the lighting criteria for the exterior are an appropriate amount of light and creating an aesthetically pleasing building to enter or drive past in the evening/night hours. The lighting can create an even or dramatic entrance but cannot be obtrusive to the passerby or the person entering the building. Objects and people on the area should have a good modeling and color appearance. Evaluation of Existing System: The color rendering for the bollards, which are located near the stairs have a good color rendering for the people entering the building. The pole fixtures provide a decent ambient light over the surface area. The current pedestrian lighting is in conjunction with the remainder of campus and will not be altered. The redesign will add façade lighting that will accentuate the architecture of the building. The sparkle is what is missing from the current design of the building exterior design and will be the addition to the building. Page 15 of 57
Schematic Design: In the schematic design phase the symbols and colors of the City and University were to be incorporated with the architecture. The orange on the legs was to be isolated with spot lighting and the blue was to place a ribbon of color around the existing lower level square of the building. Along with this design the sun was to be incorporated as a symbol that would be turned on during evening events. This design after evaluation was determined to be less visible from the pedestrian level than initially designed. It also interfered with the housing located on two of the four corners. The Sun is a symbol of the City of San José. The colors of San José State University. Page 16 of 57
Tube lighting will be attached to the concrete façade where there are indentations in the pre-cast concrete. Tube lighting will be used to highlight the edges of the box that runs along San Fernando St. Andrea Hauber; Lighting/Electrical Architectural Engineering A combination of up and down lighting will be used to give an even orange glow to the exterior legs of the building while limiting unnecessary light pollution. Low CRI is acceptable to illuminate the building. Lamp type must be able to be focused. For the final design of the exterior of the library a more minimal design will be used. This will allow for the building geometry to be viewed at night without the light being intrusive on the surrounding residences and campus. Page 17 of 57
Final Redesign: In order to accentuate the architecture of the library the façade lighting is to use linear lighting to accentuate the geometric complexity of the building. The TIR Tubular Series will allow for the architecture of the building to be evident. Page 18 of 57
Lower block: Four TIR Tubular Series 4 Ovoid Series @32-8 as shown in Elevation 1 (TBR-4-GEN-DU-392) Upper tubes: Three TIR Tubular Series 6 Ovoid Series @ 59 (TBR-6-GEN-DU-708) The structural connection and moisture protection for the bracketing of the Ovoid Tubular fixture will be detailed in the structural breadth topic section of this thesis. Maintenance: The upper lamp in the end cap can be replaced from roof level. The lower lamp in the bottom end cap is to be replaced using a lift. The re-lamping is limited to the end caps to ease the process of re-lamping multiple fixtures throughout the tube. Conclusion: The purpose of the lighting concept is to give the needed sparkle to the building. With the pedestrian lighting being sufficient, the façade lighting will emphasize the geometry of the building. Page 19 of 57
