  8. Presentation Outline • Building Summary • Classroom Lighting • Transition Space Lighting • Auditorium Lighting

  9. Classroom • Space Conditions • Walls – Gypsum board – Light grey • ρ = .51 • Ceiling – White gloss gypsum – 11ft. High • ρ = .68 • Floor – blue color carpet • ρ = .32

  10. Classroom • Design Goals • Functions – lectures, movies, displays, gatherings • To allow different scenes for certain tasks • Create a large space by illuminating all surfaces • Provide adequate light for easy viewing from the back row • Provide an energy efficient system that could be used continuously throughout other similar spaces

  11. Classroom • Controls • Two dimming switches will be applied to the different fixtures • Each type of fixtures will run on one circuit to control box • Dimming switch will allow 10 to 100% dimming using high frequency ballasts

  12. Classroom • Design Criteria • Power Density = 1.6 W/sqft. • Vertical Illuminance • Marker board and speaker = 10 fc • Horizontal Illuminance • Circulation = 10 fc • Reading/Writing @ seating area = 30 fc

  13. Classroom • Layout of Fixtures 8” recessed downlight w/ 26W compact fluorescents Max Intensity = 953 cd

  14. Classroom • Layout of Fixtures 8’ triangular pendants w/ 4-32W T8 fluorescents Max Intensity = 1424 cd

  15. Classroom • Details of Pendant Fixture

  16. Classroom • Results and Calculations Pendant @ 70%: Max Intensity = 1000 cd Recessed Downlight @ 70% Max Intensity = 670 cd Power Density = 1.44 W/sqft

  17. Classroom • Results and Calculations

  18. Classroom • Results and Calculations Ceiling Max Illum: 104 fc Ave. Illum: 35 fc Side Walls Max Illum: 22 fc Ave. Illum: 12 fc Front wall Max Illum: 18 fc Ave. Illum: 7 fc

  19. Classroom • Results and Calculations Entrance Wall Max Illum: 17 fc Ave. Illum: 9 fc Luminance Ratios Ceiling to Wall: 2.6 to 1 Wall to Floor: 1 to 1.3 Ceiling to Floor: 2 to 1

  23. Presentation Outline • Building Summary • Classroom Lighting • Transition Space Lighting • Auditorium Lighting

  24. Transition Spaces • Vestibule (1) • Foyer (2) • Lobby(3) • Prefunction(4) • Corridor (5) • Coat Room (6) 4 2 1 3 6 5 Spaces Lead to two different entrances of the auditorium From the prefunction space and near the coat room.

  25. Transition Space and Auditorium • Controls • All lights will be controlled by a preset dimming track system located in electrical room • Fixtures will be divided into zones connecting to one circuit. • Panel system will allow change of scenes with a push of a button

  26. Transition Spaces • Space Conditions • Walls-either limestone or wood paneling, • Carpet floors • Eggshell painted ceilings • No daylight • 3 ceiling heights • 8’, 13’, 16’ ρ = .50 ρ = .39 ρ = .80

  27. Transition Spaces • Design Goals • Establish aesthetic attraction to new spaces • Provide Adaptation at Entrances/Transition Spaces • Allows eyes to adjust to changing light levels • Create energy efficient system • Lighting to create flow for traffic • Maintain proper illuminance for activities within the space

  28. Transition Space • Design Criteria • Power Density = 1.8 W/sqft. • Vertical Illuminance • Facial lighting = 10 fc • Horizontal Illuminance • Reading or Writing tasks = 30 fc • Traffic = 10 fc on floor

  29. Transition Spaces • Layout of Fixtures • Lobby 8” downlights w/ 26W compact fluorescents Max = 558 cd @72% = 400 cd

  30. Transition Spaces • Layout of Fixtures 8” downlights w/ 32W compact fluorescents Max = 1114 cd @72% = 800 cd

  31. Transition Spaces • Layout of Fixtures 4’ linear wallwashers w/ a 54W T5 fluorescent lamp Max = 1910 cd @65% = 1340 cd

  32. Transition Spaces • Layout of Fixtures 4’ linear fluorescent perimeter fixture Max = 843 cd @65% = 550 cd

  33. Transition Spaces Power Density = 1.44 W/sqft Ave. Floor Illum. = 32 W/sqft.

  34. Transition Spaces • Results for fully lit Lobby Ceiling Max Illum: 34 fc Ave. Illum: 10 fc Wood Ave Top Illum: 70 fc Ave. Bot. Illum: 35 fc Limestone Ave Top Illum: 30 fc Ave. Bot. Illum: 15 fc

  35. Transition Space • Results for Fully Lit Lobby Elevator Ave. Top Illum: 130 fc Ave. Bot. Illum: 14 fc Ave. 6’ Illum: 26 fc

  36. Transition Space • Results for Fully Lit Prefunction Columns Top Illum: 37 fc Bottom Illum: 13 fc

  37. Transition Space • Results for Fully Lit Prefunction 13’ Ceiling Max Illum: 14 fc Ave. Illum: 9 fc Wood Ave. Top Illum: 70 fc Ave. Bot. Illum: 18 fc Elevator Ave. Top Illum: 110 fc Ave. Bot. Illum: 14 fc

  46. Presentation Outline • Building Summary • Classroom Lighting • Transition Space Lighting • Auditorium Lighting

  47. Auditorium • Space conditions • Walls – gypsum board w/ acoustical tiles , ρ = .65 • Back wall – fabric cover panels, ρ = .50 • Ceiling – dropped w/ over lapping panels • ρ = .80 • Floor – neutral color carpet, ρ = .42 • Ramp angle = 4.7° and 7° • Seating = 486 w/ 6 wheelchair spaces

  48. Auditorium • Design Goals • Functions – lectures, movies, displays • To allow different scenes for certain tasks • Establish a sense of light shining through the panels as if it was natural light • Create a lighting pattern that enhances the architectural design of the space • To create a low power illuminating design

  49. Auditorium • Design Criteria • Power Density = 2.0 W/sqft. • Vertical Illuminance • Speakers and Objects on Stage = 30 fc • Horizontal Illuminance • Circulation during videos = .2 to .5 fc • Presentayion w/. Slides = 1 to 5 fc • Reading @ seating area = 30 fc

  50. Auditorium • Layout of Fixtures 8” downlights w/ 2-32W compact fluorescents Max = 1273 cd @85% = 1100 cd
