LIGHTING
4-7
4-7.1 GENERAL:
Consideration of lighting requirements for club
facilities should include both natural and artificial sources, both
from
a quantitative and a qualitative viewpoint.
P r o g r a m m i n g and design decisions should be made by rational process
w h e r e b y the most beneficial performance can be obtained at an acceptable
cost .
Any cost/benefit analysis should take into consideration the
service life of design alternatives under consideration, their energy
c o n s u m p t i o n , and their effect on heating and cooling energy usage.
4-7.2 NATURAL LIGHTING:
Natural lighting should be considered to be
m o s t desirable for those activity areas such as lounges and dining rooms,
w h e r e the occupants can enjoy varied natural light and outside views.
F o r o t h e r a c t i v i t i e s , s u c h as administrative offices and staff work spaces,
planning for natural lighting and view by articulation of the exterior wall
Glare
o r by the introduction of overhead skylights, can be beneficial.
from direct sunlight should be carefully controlled by the provision of
a w n i n g s , louvers or blinds for times of excessive exposure.
4-7.3 LIGHTING DESIGN AND EVALUATION: Assessment of the worth of
natural lighting is largely subjective.
Practical considerations include
t h e d e g r e e t o w h i c h a r t i f i c i a l light can be saved by the introduction of
p e r i m e t e r switching zones that would facilitate the saving of power
during daylight hours.
A staccato-like rhythm of' alternating narrow
v e r t i c a l windows and solid walls can often detract from the quality of

4-7.4 NEED FOR UNIFORM CRITERIA:
It is recognized that many of the
t a s k s performed in a club do not require great visual acuity. This
p a r t i c u l a r l y applies to areas such as the bar and dining room. Lighting
c r i t e r i a in these areas should be pursued more to obtain an attractive
a n d appropriate atmosphere, rather than attempting to maintain uniform

General principles of good lighting will dictate that
