First space to consider • Gallery 1134 • Lecture Hall 1210 • Meeting Room 4287 • Outdoor Patio N Bahen Centre for Information Technology – University of Toronto

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 Bahen Centre for Information Technology – University of Toronto

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 Bahen Centre for Information Technology – University of Toronto

Gallery Design Criteria • 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) Bahen Centre for Information Technology – University of Toronto

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 ceramicfritted glass for glass panels on wall. Backlight frit glass panels from above to create a grazing effect. Bahen Centre for Information Technology – University of Toronto

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. Bahen Centre for Information Technology – University of Toronto

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: Bahen Centre for Information Technology – University of Toronto

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. Bahen Centre for Information Technology – University of Toronto

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. Bahen Centre for Information Technology – University of Toronto

Gallery Design Concept continued… Goal: To provide adequate illuminance safety in the corridor Corridor will be lighted indirectly by the light shining through the glass. Bahen Centre for Information Technology – University of Toronto

Gallery 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. Bahen Centre for Information Technology – University of Toronto

Next space to consider • Gallery 1134 • Lecture Hall 1210 • Meeting Room 4287 • Outdoor Patio N Bahen Centre for Information Technology – University of Toronto
