 Temperature conntrol image

It's a muggy August afternoon. Employee A is "dying" of the heat and wants someone to fix the air conditioning. On the other hand Employee B is wearing a sweater and shivering. Employee C says, "I'm comfortable!" and wants to know why the other two are complaining.

The dictionary defines comfort as a "condition of mind in which satisfaction is expressed within the 116 environment! While no single environment can be judged satisfactory by everybody, most people will achieve comfort in an office it it meets the following criteria:

  • Space Temperature. Uniform and between 70-78F. Slightly cooler in winter and slightly warmer in summer.

  • Absence of radiant fields and no cold windows, cold floors, warm radiators, or radiant solar heat at windows.

  • No convective drafts. This is caused by excessive cool air movement.

  • Absence of objectionable noise. Uniform, continuous noises in the 35-40 noise range are acceptable. Noises such as rattling, whistling are not acceptable.

  • Air Movement. Continuous movement with local office velocities at 30-50 feet per minute (FPM). Circulated air should be no more than 2F different from the ambient space temperature.

  • Relative Humidity. Space relative humidity (RH) controlled between 30 and 50% range. Winter at 30% and summer at 50%.

  • No Temperature Stratification. Vertical temperature differences between feet and head.

  • Clean Air. Increased levels of airborne contaminants, odors, or microbial particles will give people a sense of "sick building syndrome".
