55 Lower Level Corridor

56 Lower Level Corridor Design Criteria Curving walls and dropped ceilings are architectural features that should be emphasized Main focal points should create a sense of movement by leading people through the corridor. Brightest points shall be the ceilings followed by the walls Main Tasks Circulation for younger grades (K-3rd) Circulation for all students to the auditorium Target illuminance From Figure of IESNA Lighting Handbook, 9 th ed: Working space with simple visual tasks: 100 lx (10fc) Personal Goal: Higher than recommended due to spill daylight from the sky light over the stair case Daylight integration will not be considered for this space since it is on the lower level and in the center of the building. However, daylight will be an inspiration for the lighting. Reflection of fixtures in the glossy floor should be avoided

57 Lower Level Corridor Current Layout: Luminaires: Direct 1x4 lensed troffers Compact fluorescent down lights Lamp: Fluorescent, 3500 CCT Ballast: Non-dimming electronic, instant start Design Issues: Similar to upstairs corridor, the ceiling plane is too chaotic The walls have too little illumination Curvy wall is not accented Dropped ceilings are not emphasized Doorways to the auditoriums on east wall are not emphasized Negative reflections from fixtures on floor

58 Lower Level Corridor Schematic Redesign: Intent: A smooth transition from the heavily daylit upper level to the lower corridor Create the feeling of skylight on the ceiling A clean appearance on the ceiling plane Color accents to create visual interest and stimulate creativity Highlight architectural features Wall brightness secondary to ceiling Indirectly light the corridor Surface to display artwork Fixtures: Linear fluorescent wall washers Asymmetrical cove fixtures LED strips Lamping: Fluorescent, 5000K Colored LED Ballast: Non-dimming electronic

Ceiling plane is un cluttered. LED strips inlaid into the curvy wall and columns create visual interest.

61 Kindergarten Classroom

62 Kindergarten Classroom Design Criteria No architectural features to be highlighted Main focus is on learning and creating a relaxing atmoshpere for students Main Tasks: Reading and writing on children s s desk (26 above finished floor) Reading and writing on teacher s s desk (30 above finished floor) Reading off whiteboard VDT usage Story time with reading out loud Target illuminance From Figure of IESNA Lighting Handbook, 9 th ed: Generally- Performance of visual tasks of high contrast and small size: lx (50 fc) Personal Goal: Higher on teacher s s desk: complaint from current faculty that there is not enough light despite a reading of 60+ footcandles on desk Higher for the children. Recent studies show dramatic improvement t in test results for students with light levels close to 700 lx (70fc) Small amount of daylight integration possible on western wall (northwestern sky) Problems to avoid: veiling reflections on VDT screens and students ts desks, glare from windows, allow for blackout scenarios

63 Kindergarten Classroom Current Layout: Luminaires: Recessed direct 2x4 lensed troffers Lamp: Fluorescent, 3500 CCT Ballast: Non-dimming electronic, instant start Design Issues: More illumination to walls needed Veiling reflections visible in VDT screens and TV No separation of functions Not enough light for teacher s s desk, so she moved her desk to the rear of the classroom directly under a troffer Institutional feel with adequate light levels (~60fc)

64 Kindergarten Classroom Schematic Redesign: Intent: Support the learning process by providing increased illumination to the students and instructor Use of a high CCT lamp to mimic daylight despite a northern sky viewing window wall Increase the number of windows and provide automatic shades for shielding and black out A direct system with reflected component will be used for general illumination following the 1:8 ratio for ceiling luminance and VDT screens A task light will be provided for the instructor s s desk Fixtures: Direct Indirect fixture Recessed or pendant mounted Linear Wall Washers Lamping: Fluorescent, 4100 or 3500 for direct/indirect fixtures Fluorescent, 5000 K, for wall washers Ballast: Dimming electronic Electronically controlled shading device

Cove area created in back to accent change of task. White board task light to provide proper vertical illumination for students.

66 Kindergarten Classroom Schematic Redesign: Concept Sketch Fixtures: Asymmetrical cove fixture Blue LED accent to mimic hallway Downlighting to create a more residential feeling Wall washing to provide adequate illumination for displays and reading Lamping: Fluorescent, 5000 K for cove Fluorescent, 4100K or 3500 K Ballast: Dimming electronic Using an architectural feature (change in ceiling height) to accent a designated task (story time). Helps create visual interest in the room.

67 Kindergarten Classroom Schematic Redesign: Concept Sketch Fixtures: Linear Wall Washer Lamping: Fluorescent, 4100K or 3500 K Ballast: Electronic, Non-dimming Bringing light to the walls makes the room feel more spacious and brighter

68 Auditorium

69 Auditorium Design Criteria Height of the space, over 20,, should be emphasized along with the changes in color and textures along the walls Main focal point is the stage, however, more illumination should be provided in audience prior to performance or presentation for supervision purposes. Main Task: Congregation Task Plane laps of viewers: ~26 above finished floor Target illuminance From Figure of IESNA Lighting Handbook, 9 th ed: Simple orientation for short visits: 50 lx (5 fc) Working space with simple visual tasks: 100 lx (10fc) Personal Goal: Higher than 5fc or 10fc to provide adequate illumination for instructors to supervise children upon entering and leaving the auditorium Daylight integration not necessary due to central location of building Glare problems may arise from direct view of fixtures

70 Auditorium Current Layout: Luminaires: 8 inch compact fluorescent downlights spaced over 14 feet apart with a wide distribution Lamp: Fluorescent, 3500K Ballast: Non-dimming electronic, instant start Design Issues: The lack of light to the ceiling dwarfs the space and gives it a cave like appearance. Lighting is way too dim despite the adequate light level of 10 fc. Atmosphere is very tense and uninviting

71 Auditorium Schematic Redesign: Intent: Light to the higher reflectance paint on the upper portion of the walls (80%) Indirect lighting to the ceiling with 6000K Mimic sylight Use direct downlights for facial rendering over the audience Accent uplights around perimeter to emphasize texture of brick at lower portion of wall Create a more welcoming place for visitors All lighting will be on dimmer control Fixtures: Asymmetrical fluorescent cove fixture Compact fluorescent downlight with flood distribution Metal Halide wall washers for perimeter Lamping: Fluorescent, 5000K for cove Fluorescent, 4100 or 3500K for downlights Metal halide for wall washers Ballast: Dimming, electronic

76 Conclusion Human Factors My designs have addressed improving human factors such as visual comfort in kindergarten classroom, media center, and computer lab mood and atmosphere in the auditorium and corridors task performance in every space discussed

77 Conclusion Economic & Environment Factors With my designs, I also take into account economic and environment factors such as: Maintenance I have tried to be consistent with fixtures, reusing same fixtures throughout the building Less than 10 different types of fixtures with many sharing the same lamping Energy By incorporating daylight into the Lord Stirling Community school, light levels and atmosphere will be greatly improved without the use of more energy I predict energy consumption to drop with the added daylighting

78 Conclusion Architectural Factors A major goal of my lighting design is to complement the architecture By accenting existing architectural features and creating a few more of my own, my designs help to create a more visually interesting spaces with a style that speaks of more than an educational institution
