Appendix E: Space Requirements 721
Ceiling Plenum Space
Notes for Ceiling Plenum Space Tables:1. Assumptions: 2″ fire proofing on beam, 6″ fluorescent light depth, 51 ⁄ 2″ floor slab thickness, 2″
suspended ceiling thickness.2. For depth from beam to ceiling, add 4″ to above figures.
3. For depth from underside of slab to light, add depth of beam plus 2″ .
4. * indicates beam protruding through ceiling.
