Compound annual growth rate of 17% from 1996 to
2001 |
|
Approximately 35,000 facilities housing 1.4
million people |
|
Typical Customer: 82 year old woman |

|
Opportunity |
|
Growth curve will resume: aging boomers |
|
Developers are recognizing the need for better
lighting |
|
Liability/Safety: 8 of 10 people killed by falls
are over 65 years old |
|
Marketing: Facilities that are properly lit
“sell and retain” better |
|
|
|
|
A caring and comfortable environment gives the
residents a greater sense of safety, personal independence and well-being. |

|
|
The Aging Eye |
|
Lenses grow thicker, more opaque, and
increasingly specked with protein deposits |
|
“Like a computer screen with the brightness and
contrast knobs turned down” |
|
Less light reflected, colors blur, yellowish hue
dominates. |
|
Contrasting light levels are painful. |
|
|
|
|
|
The Aging Eye (con’t) |
|
Older person is more sensitive to glare |
|
Less able to focus |
|
Less sensitive to color |
|
Shadows can look like water puddles |
|
Light is vital to production of melatonin |
|
Oregon mandating lighting standards be followed |
|
|
|
|
|
|
“Better lighting is a simple measure that allows
the elderly to maintain their independence and increase their sense of
well-being.” |

“Naked” lamps are the worst for older eyes |
|
Produce glare that can be painful and
disorienting |
|
Always use electronic ballasts |
|
Flicker can be dangerous for dementia patients |
|
Task lighting is a must |
|
Reading/paperwork areas |
|
Countertops/stoves/sinks |
|
|
|
|
|
Use high color rendering lamps (80 CRI or
better) |
|
Lots of light in the bathroom |
|
Where most accidents occur |
|
Don’t use “Hollywood” bars |
|
Minimize access to lamps |
|
Minimize patterns and textures |
|
Perceived as “dirty” |
|
|

Color Temperature of fluorescent lamps |
|
Regional preferences: |
|
|
|
Northern: 2700K and 3000K |
|
Middle:3000K to 3500K |

ADA (Americans with Disabilities Act) |
|
“Objects projecting from walls located between
27” and 80” above the floor plane must not protrude more than 4” from the
wall” |
|
Applies only in public corridors used as
exitways |
|
|
|
|
|
Adaptation Control |
|
Avoid abrupt changes in light levels in
transitional areas, especially during the day from indoors to outdoors |
|
Adaptation takes longer in aging eyes |
|
Adjusting from light to dark takes considerably
longer than dark to light |
|
|
|
|
Light pavement and steps evenly (DL’s) |
|
Use lanterns with opaque or textured glass |
|
Hanging fixtures should be high and rated for
damp location |
|
|
|
|
Create a non-institutional look with decorative
lighting |
|
Keep transition to outdoors in mind (100fc) |
|
Use skylights to supplement daytime |
|
|
|
|
Creating comfort is the key |
|
Low glare is primary design factor |
|
Sconces may need to be ADA |
|
|
|
|
Critical area for even lighting |
|
Sconces must be ADA compliant |
|
Use lamps with compatible color temperature and
CRI |
|
Never use only downlights: creates “cave” effect |
|
|
|
|
Wide distribution recessed with good cutoff |
|
General diffuse indirect lighting to supplement
DL’s |
|
Shield any bare lamps |
|
Mount chandeliers high |
|
|
|
|
High ambient level (50 fc) |
|
Provide task lighting in appropriate areas |
|
Low ambient level near TV to avoid glare |
|
Light bulletin boards, coffee/tea service area |
|
|
|
|
Undercabinet lighting for food preparation |
|
Good color rendition: 80 CRI or better |
|
Good ambient level : 30 fc |
|
Try to avoid highly polished countertops |
|
|
|
|
3-way table lamps |
|
Avoid halogen lamps for reading or task lighting |
|
Remember uniform light levels |
|
Put sconces on both sides of dressing mirrors |
|
|
|
|
|
|
|
|
High ambient- 50 fc in shower, 60fc at mirror;
long fixture over big mirror |
|
Use frosted or opaque source shields |
|
High output (50w PAR30) showerlight |
|
|
|
|
Conceal all sources |
|
Uniform path lighting |
|
Minimize brightness variations |
|
Avoid shining lights into eyes or in windows |
|
|
|
|
|
Initial Cost vs Life Cycle Cost: |
|
|
|
Typical payback for using linear/compact
fluorescent vs incandescent is 2-3 years |
|
|
|
Payback is based on reduced energy consumption
and maintenance savings |
|
|
|
|
|
More light output per watt used: |
|
Recessed savings of 30-40 % |
|
Surface or pendant savings of 60 to 70% |
|
Longer lamp life (10,000 hrs vs 1,000 hrs) |
|
Lower maintenance costs, increased safety |
|
Long burning hours maintains architectural
appeal of building |
|
|
|
|
|
Low operating current means fewer circuit
breakers and circuits |
|
Electronic ballasts offer additional energy cost
savings and no-flicker operation |
|
A MUST for facilities with dementia patients |
|
Lower operating temperatures |
|
Lower HVAC loads |
