General design goals for all four spaces

• To provide quietness, non-cluttered, and a clean
  look
• To highlight architectural elements and attract
  attention
• To provide an energy efficient design
• To maintain design metaphor throughout all the
  spaces

9
First space to consider

• Gallery 1134
• Lecture Hall 1210
• Meeting Room 4287
• Outdoor Patio

N
10
Gallery
The gallery space is a corridor enclosed by a
glass lined wall of auditorium 1130
and a large plane of windows facing the
pedestrian walkway of St. George Street.
N
Ground Floor Plan
11
Gallery
The large windows adjacent to the sidewalk makes
this a very visible area from outside.
Computer lab and auditorium walls are lined with
glass panels, which will provide sunlight into
those spaces
N
Ground Floor Plan
12
Design Criteria
Gallery

• To direct movement through the corridor
• To be adequately lit to promote safety
• Direct glare and shadowing issues from overhead
  luminaire should be considered
• To add visual interest to the corridor space
• Target illuminance
• Horizontal 5 fc (50 Lux)

13
Gallery
Design Concept
Goal To eliminate clutter in the space and
achieve a clean look
Corridor will be lighted indirectly by the light
shining through the glass.
Use patterned ceramic fritted glass for glass
panels on wall.
Backlight frit glass panels from above to create
a grazing effect.
14
Gallery
Design Concept continued
Wall wash fixture with glass wall detail
Fixtures will be placed inside the auditorium and
computer lab side of the glass to avoid glare for
occupants of those rooms.
15
Gallery
Design Concept (Ceramic Fritted Glass side note)

• Ceramic fritted glass consists of a ceramic
  based paint screen-printed onto glass. The glass
  is then heat strengthened or toughened which
  fuses the paint to the glass creating a permanent
  durable coating - National Glass Catalogue and
  Reference Guide 2000
• Can be used to filter light or reduce glare with
  different pattern designs.
• When fritted glass is used in conjunction with a
  light source, it can create a glowing visual
  appearance.

Examples of Application

Gallery
Design Concept continued
Goal To enhance architectural elements (curved
glass wall)
The lighted fritted glass panels will create a
glowing curved wall appearance for onlookers
from the outside.
Fiber optics lining the top and bottom of the
curved wall, creating movement along the corridor.
17
Gallery
Design Concept continued
Goal To attract the attention of pedestrians
looking through windows
The lighted fritted glass panels will create a
glowing curved wall appearance for onlookers
from the outside. It also represents the metaphor
for the project, where the glowing wall
symbolizes a source of knowledge and information.

Lighting Equipment
Side emitting fiber encased along top and bottom
of curved wall in Gallery.
Ceiling mounted, small concealed, one lamp
fluorescent T-8 wallwash fixture.
Fritted glass washed by linear fluorescent
fixture will become a light source itself,
lighting up the corridor. The patter of the frit
should be horizontal to promote movement along
the gallery.

This 85 seat Lecture Hall features eight rows of
seats on a stepped floor. The room does not have
windows.
Ground Floor Plan
22
Design Criteria
Lecture Hall

• Consider veiling reflections on table and
  blackboard, glare, and reflected glare issues of
  the space
• Lighting of the vertical surfaces such as
  chalkboards
• Visual appearance of lecturer at the front of the
  room and shadows
• Provide different levels of illumination for
  different tasks (lecture, note-taking,
  audiovisual presentation)
• Target Illuminance
• Horizontal 50 fc (500 Lux)
• Vertical 50 fc (500 Lux)

23
Lecture Hall
Design Concept
Goal To provide an even ambient lighting scheme
that causes minimal shadow and glare
Suspended indirect/Direct fixtures (with LED
lights on the bottom side) to provide a
comfortable, diffuse illumination for the entire
space.
Fixtures will be aligned orthogonally to the
orientation of the rows of tables to avoid glare
from the downlight portion of the fixtures.
24
Lecture Hall
Design Concept continued
The LED on the fixture continues to symbolize the
project metaphor
25
Lecture Hall
Design Concept continued
Goal To highlight the architectural detail in
the space
Cove lighting for drop ceiling to illuminate the
perimeter of the room, preventing the caved-in
feeling. The lights will also highlight the
mahogany wood architectural detail mounted on the
walls all around the room.

Lecture Hall
Control Systems
Requirements
Special controls are need to set different scenes
and zones of lighting for the lecture hall. The
control should have the capability to dim
different groups of lighting required for various
tasks and to achieve a desire illuminance level
on the various workplane levels.

• At least two different scenes will be required
  for
• Regular lectures and note-taking
• Audio-visual presentations

31
Lecture Hall
Control Systems continued
A number of dimming zones must be set up for the
linear fluorescent fixtures so that there will be
the same illuminance level for the different
desktop elevation levels of the room. An
additional zone should also be set up for the
front of the room and another zone for the cove
lighting around the room.
Zone 1 Front of the room for vertical surfaces
and face rendering
Zone 2,3,4 Above desks and seats for tasks such
as note taking and reading
Zone 5 Cove lighting region

South Courtyard
Located in the southwest end of the Bahen Centre.
All the rooms on the south side of the building
has a view of the courtyard.
Ground Floor Plan
It features a green lawn area, groups of trees,
and a custom designed water feature
45
South Courtyard
The water feature consists of three
concrete-casted silos used to collect rain water.
The collected rain water is then drained into
troughs and trickle down to the pool. It then
flows to a lower level trough (which runs
north/south) and to another trough which is at
street level to College Street.
46
South Courtyard
Design Criteria

• To promote safety and security to the area by
  providing sufficient lighting at night
• To direct movement through dark paths in the
  courtyard
• To attract attention to the water feature the
  building, while eliminating glare to the adjacent
  buildings caused by lighting
• Target illuminance
• Horizontal 5 fc (50 Lux)
• Vertical 2 fc (20 Lux)

Circular wall lights will be place at steps on
the pathway that runs north/south from the
courtyard to provide enough light for pedestrians
walking on the steps. LED marker lights will be
casted into the concrete ramp for handicap access
next to the steps on the path. This will create
an airport runway effect that will guide people
in or out of the courtyard to the street.
