The University of Louisville Health Care Outpatient Center, in Louisville, Ky., had a problem with its server room overheating. The 8 x 12-ft room houses server and telecom equipment that is vital to the center's daily operations. The equipment runs 24 hrs a day and needs to be cool at all times to avoid malfunctioning, hardware damage, or system downtime. The problem surfaced when the setpoints of the building's central HVAC system were adjusted to turn the system off at night. As a result, equipment in the server room became excessively hot and was shutting down at night, incapacitating the health-care center for hours at a time.
