A large office space has an average occupancy of 30 people from 8:00 A.M. to 5:00 P.M. Light-

ing is 1.5 W/It2 of recessed, unvented fluorescent fixtures on from 8:00 A.M. to 6:00 P.M. Com-

puters, photocopiers, fax machines, etc. create a heat gain of 1 W/ft2. Compute the sensible and latent beat gain at 4:00 P.M. for the space, assuming a floor area of 4000 ft". For the sensible heat gain, estimate the radiative and convective portions.
