Heating and cooling are less of a problem in offices than in factories and other work environments where high ceilings allow heat to rise and where there is often a constant flow of trucks and other moving and handling equipment through large doors. These conditions make it difficult to maintain a constant temperature. Solutions range from selection of suitable clothing to space heating or cooling devices.
Ventilation. Unpleasant and noxious odors can be distracting and dangerous to workers. Moreover, unless smoke and dust are periodically removed, the air can quickly become stale and annoying.
