Goals of Office Lighting
Effective communication
 Written, visual, aural,
electronic, face-to-face
Enhance productivity
 More comfortable visual
environment may lead to
increased productivity
Aesthetics
 Worker perceptions, mood
Use energy efficiently
 Code compliance
 Lower energy costs
13
Direct Lighting
 90-100% downward
 Distribution varies from
widespread to concentrated
(shielding media )
 High CU, system efficiency
 Potential glare problems
(direct, reflected)
 Potential “cave effect”
(deep cell louvered fixtures)
 Potential discomfort glare
outside normal field of view
14
Indirect Lighting
 90-100% upward
 Relies heavily on
ceiling/wall surfaces

Trends in Office Lighting Design
 Dimming & Controls
– Allows the user to reduce overall energy
consumption by integrating preset limits on
usage
• Utilize switches, timers, occupancy sensors, etc
– Daylight Harvesting
• Photosensors

Light levels
Glare
Color
Uniformity
Visual Interest
How does LED impact?
19
Visual Comfort
 Light Levels
– Lower levels are visually comforting
• May lack adequate levels to perform certain tasks
– Higher levels are more task oriented
• May be less aesthetically pleasing
– Choosing the “right” light levels for the
environment is critical to visual comfort
• IESNA can be referenced for recommended light levels
for individual tasks
 Glare
– Direct Glare: bright fixtures and windows in line of sight
– Reflected Glare: light sources reflected on glossy surfaces
20
Visual Comfort
 Color
– Important in differentiation of the perception of
light.
– Measured by color temperature and color
rendering (CRI). Higher the CRI, truer the color is
perceived
• High CRI = Retail, High end office spaces
• Low CRI = Parking garages, lots
 Uniformity
– Bi-product of efficient lighting
– Vertical surface brightness
• Sense of Spaciousness
– Less stress on the eye
21
Visual Comfort
 Visual Interest
– Non-uniform lighting with peripheral emphasis
(accent lighting)
– Brings presence to architecturenim
 LED Impact
– Earlier solutions offered lower delivered lumens
to minimize source brightness and glare
– Optimized solutions offer higher LPW while
maintaining visual comfort
– Control friendly solutions with minimal cost add
22
Legislation and Recommended Practice
ASHRAE
EPAct

• Loose Hardware makes installation a challenge
o Pre-Wiring & Assembled Required
• Must remove 90% of existing luminaire before Kit install
• Assembly and wiring still required for many versions
• Creates equal install time vs. fixture
o Thermal Control
• Unpredictable thermal impact on lumen output
o Will the Kit Fit?
• Complications in fitting 3rd party fixtures (non-universal)
• Mounting is vastly different from LFL

Linear LED Key Design Goals
•Platform Approach
•Needs to be quickly/easily integrated into existing
architectural linear platforms across many brands
•Exceed Fluorescent
•If delivered lumens per watt, and color quality does not
exceed fluorescent, then no value proposition exists
•“Fluorescent-Like”
•Must “behave” like fluorescent. We can not
introduce visual discomfort (glare)… regardless
of tipping point discussion
•Gen I- Existing Platforms
•In order for early technology adoption across varied
product, must integrate in existing fixture platforms
•Gen II- “Form follows LED”
•Now that we have a viable LED module the sky is
the limit.
