Sketch Series 4
In Sketch Series 1, you observed the light zones in the Gatewood
Studio Arts Building.
In Sketch Series 3, you measured the illuminance levels and
material reflectances of a chosen space in the Gatewood Building.
For Sketch Series 4, in groups of three, note the type of
luminaire in the space you measured in the last class. Observe the following:
- Type of
luminaire (uplight, downlight, etc.)
- Mounting type
- Lamping
- Construction
- Manufacturer (if
possible or find the closest match online)
- Study the
photometrics of the luminaire: lumens and lighting distribution
- Material and
finish
- Lensing
- Function (fixed,
adjustable, etc.)
- Ballasts
- Environment
- Shielding
Draw sketches of the space to show the existing luminaires.
- identify
the purpose of the space
- identify
the purpose of lighting, including an identification of ambient, task,
accent, and sparkle lighting.
- describe
the effect of each luminaire in the space.
- based upon your observations and reflections, provide recommendations for improving the lighting environment.
Studio Stairwell
a. Type of luminaire (uplight, downlight, etc.)- semi-direct
b.
Mounting type- bracket (wall mount)
c.
Lamping- fluorescent tube
d.
Construction- rectangular shape with one side glass, 2 lamps
e.
Manufacturer (if possible or find the closest match online)- LAMAR
lighting
f.
Study the photometrics of the luminaire: lumens and lighting
distribution- semidirect
g.
Material and finish- brushed aluminum
h.
Lensing- transparent glass with serrated bottom
i.
Function (fixed, adjustable, etc.)- fixed
j.
Ballasts- 2lamp ballast
k.
Environment- circulation stairwell
l.
Shielding- none except for the serrated bottom
a. purpose of the space is for circulation
b. ambient lighting
c. it provides a significant amount of diffused light
d. I wish there was lighting closer to the ground to better see
where to walk.
Dining room
a.
Type of luminaire (uplight, downlight, etc.)- multi-directional
b.
Mounting type- screw in
c.
Lamping- incandescent
d.
Construction- tungsten filament housed in glass
e.
Manufacturer (if possible or find the closest match online)- GE
f.
Study the photometrics of the luminaire: lumens and lighting
distribution- illuminates the table
g.
Material and finish- brushed metal
h.
Lensing- glass
i.
Function (fixed, adjustable, etc.)- fixed
j.
Ballasts-
k.
Environment- dining room (chandelier)
l.
Shielding- none
a. purpose of the space is for eating
b. task lighting
c. the lighting illuminates the table for eating but also the rest
of the room.
d.I think the lamps should have a type of shield. They produce so
much glare that you cannot look directly at the fixture from any angle.
Kitchen
a.
Type of luminaire (uplight, downlight, etc.)- multidirectional
b.
Mounting type- screw in
c.
Lamping- incandescent
d.
Construction- tungsten filament housed in glass sphere.
e.
Manufacturer (if possible or find the closest match online)- GE
f.
Study the photometrics of the luminaire: lumens and lighting
distribution- gives a soft glow, not enough to light the space thoroughly at
night.
g.
Material and finish- frosted glass
h.
Lensing- frosted glass
i.
Function (fixed, adjustable, etc.)- fixed
j.
Ballasts- glass
k.
Environment- kitchen
l.
Shielding- none, though the glass is semi-transparent, acts as a
screen to diffuse the light.
a. purpose
of the space is for preparing food
b. task
lighting
c. it
gives off a glow of diffused light and is supposed to provide ample amount of
light to perform tasks.
d. This
type of fixture and lamp does not work in the space. Every time you turn to the
counter, your shadow falls over what you are doing, making the light completely
useless. I have to turn sideways half the time to complete the task at hand. I
would install a type of track lighting around the space along with recessed and
task lights underneath the cabinets.
