Luminaire based controls
• Rotating switches• Pull strings• Touch plates• The “clapper”

Remotely located controls
• Toggle switches (2-,3-,4-way)• Dimmers• Timers• Occupancy Sensors• Daylight sensors• Centralized control/dimming systems

Centralized Controls
• Local monitoring and control– Locally with switches, remotes– Via computer– HVAC coordination– Daylighting coordination
• Distance monitoring and control– Typically computer– Phone
• Facilities management
Match colors and textures
Photoelectric sensors
Photoelectric Sensors
Maximize energy efficiency: part of a well integrated design
Occupancy sensors
Products
• LiteTouch for dimming systems– Most common on medium scale projects– Most options for finishes
• Lutron for residential style dimming• Wiremold Company for wire
management needs
Lutron’s Sivoia QED (see electronic brochure)
Circuiting to save energy
Accomplished by split-wiring of fixtures
Graphic standards for schematics
Different drawings
• Design reflected ceiling plan– Hatching or shading for materials– Some notes or lighting to show intent
• Construction drawings level RCP– Lighting, sprinklers, HVAC, signage, projectors, etc.– Materials and dimensions for all construction and
lighting– On small projects, include switching, data, etc.
• Switching plan– Light switch location– Circuiting of fixtures
• “Lighting plan” – same as switching• Power and data plan
– Especially important for high-tech systems, wired classrooms and meeting rooms
Design RCPS
• Must show lighting strategy (uplighting, downlighting, whatever)
• Must show ceiling materials graphically (where appropriate)
• Indicate varying soffit heights where appropriate
• Key to fixtures and materials
Design Development and Construction Documents
• Some sort of key• Ceiling materials and Lighting• Ceiling heights and materials• Notes about materials• References to larger-scale details• Not-so-fun things:
– Exit signs, emergency and strobe lighting– Sprinkler heads– Registers and diffusers
• Sometimes casework and furniture, dashed, for reference
Dimming/Switching Plans
• Purpose is to indicate location of controls and groupings of fixtures onto circuits
Switching:Considerations
• Consider location and appearance of controls• Consider fixture grouping• Budgetary constraints or opportunities• Consider operation
– Switched, dimmed, remote controls, PDA controls– Pre-set scenes at control– Pre-set scenes at central dimming station, computer
interface, or telephone activation• Consider operators
– Homeowner, superintendent, office manager, person in an office closest to the switch
– Dimming systems physical constraints– Integrated systems with daylighting and mechanical
systems
“Scenes”
• Preset dimmer values• Consider the different possible uses of a
space• Sometimes a luminaire is off

More complex scenes
• Indicate with notes on switching plan• Show an enlarged plan of a bank of
switches• Indicate using a schedule for switches• Provide a dimming schedule for
complicated systems– Some use low voltage switches and a central
controller– Some can replace existing switches with Radio
Frequency (RF) controls
Testing your lighting
• Use Revit to model• Daylight and/or electric• Still or animation
Start with daylighting
• Single views: use location
Capture axonometric view
• Capture the following views– Turn on sun path too– Today, right now– Winter Solstice– Equinox– Summer Solstice
Harvesting daylight:Light the back wall
• Perspective view– Interior without a light shelf– Add light shelf– Test at least 4 variations– Change height, depth, angle of shelf– Change angle of ceiling
• Keep exposure value the same
Solar studies
• Study room over course of a day• Study room over course of a year• Unless you’re rendering, get rid of
the light shelf
For a single day…
For a year…
