What makes the air “hot”? Moving heat in and out of buildings is more complex than simply heating and cooling the outdoor air. While outdoor air is typically preconditioned before becoming primary system air, there is often a need for further cooling or reheating for thermal comfort purposes.

Chillers may be the culprit. Noise is frequently overlooked in the design of mechanical equipment, only becoming a problem once the equipment is installed and the neighbors start complaining. If the local authorities find that a site has violated noise ordinances, the situation needs to be remedied quickly to avoid legal action.
