14 solid-state dimmer switches for energy savings and brightness control. □
Fluorescent tubes that imitate natural light emit only about 70 percent as much light as a cool-white fluorescent lamp of similar wattage.
Where a fixture allowance is provided, it should be spelled out, e.g., 2' x 4' fourlight, 40-watt fluorescent lamp per 80 square feet of rentable space. This results in 67 to 70 foot candles, more or less, depending on the height from the floor and the reflection of surrounding colors. You may need to provide for the following: □
Outlet allowances for both light and low voltage equipment
□
Special outlets for special communication equipment, such as Telex, TWX, PBX, telephone switchboard, intercoms, music, etc.
□
Under floor ducts or conduits for telephone and other lines
□
Clock and drinking fountain outlets. (These should be on separate circuits or they will go off whenever lights are turned off.)
□
Water cooler
□
Alarm system
□
Capacity of electrical panels (Allow ten percent for future growth.)
□
Dimmer switches for certain areas, (i.e., therapy or X-ray areas)
2.7 EXTERIOR LIGHTING Again, there are numerous fine points, which can make your project safer and more comfortable. Some you may consider and provide for are: □
Good lighting reduces night-time burglaries.
□
Customers and staff feel safer in a well lit parking area.
□
Illumination of walks, ramps, and curbs reduces chances of falls on slippery wet surfaces.
□
Properly placed exterior lighting can help to enhance the beauty of your building.
□
Exterior lighting generally should be well diffused, so that it doesn't shine uncomfortably in the eyes of persons walking or driving near your building.
□
All doorways should be brightly lit for security and for ease in locking and unlocking the door.
□
It's desirable that outside lights be switched on and off automatically by a timer switch or by a photoelectric switch if you want these lights on all night. © DrFernandez.com 2008
