Levels
Target level 50 FC at desk height (stipulated UofT required lighting level)Minimum 40 FC at desk heightMaximum 75 FC at desk height
As there is always variation across the room, architects/contractors are asked to pay particular attention to:
1) performance of specified fixture. Engineer’s lighting grid must conform with the speficied fixture/reflector
2) Seating at walls and last row. typically under-lit
3) Variation in throw distance due to tiered seating
Terminology
Zone: AREA of room being lit
Level: AMOUNT of lighting in given zone A room with options of 50% and 100% lighting has 2 levels A room with an on/off switch only has one level (not 2)
Banking: Alternating fixtures or bulbs within a ZONE in order to produce variable LEVELS

Blackboard Lights
Lighting for boards is typically ceiling mounted, directed on blackboards(separate bank)
If possible, prefer mounted directly above boards as per MS 3154(LED strip in ridge above blackboards, shown above)
With vertically double-hung boards, attention to be paid to try and avoid ‘shadow’ of upper board obscuring top edge of lower board(see below; example from pb 250)
