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…
