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…
