Seasonal Changes for Air Conditioning and Heat

Hale Hall

Weather in the Fall and Spring can significantly fluctuate from hot to cold and cold to hot within a matter of days. The heating and air plant that supplies Hale operates on a two-pipe system (supply and return) that cannot be switched on and off from AC to heat or heat to AC without significant adjustments.

Switching to heat or AC requires that the water system be bled and changed over. After doing this it is not easy to switch back should we get a change in temperatures.

The Office of Facilities carefully monitors temperatures and makes decisions about when to convert to heat or AC. When the heat or AC first comes on, be sure to check on the adjustments available on your units. Each residence hall has different types of controls so if you have any questions regarding adjusting your heat or AC, contact your friendly neighborhood RA.

Two-Pipe System Operation

The following requirements must be met to switch over the two-pipe systems from cooling to heating using the Evansville, IN Weather Conditions | Weather Underground website:

Prior to switching over the buildings, the Utility Services Manager informs the Assistant Vice President for Facilities Management and Campus Operations. The building zone temperatures are monitored to ensure temperatures are within the campus standard of 68-78°F.

Please note that in the Spring the heat may be turned off prior to meeting the temperature guidelines for turning on air conditioning. This will be determined by the Office of Facilities.
