Heating & Cooling Policy

DAS/General Services Enterprise has implemented cost-saving temperature control policies throughout the Iowa State Capitol Complex and leased facilities. Buildings are heated to 68 degrees Fahrenheit (±3 degrees) and cooled to 78 degrees Fahrenheit (±3 degrees) during normal business hours. Building temperatures will be set back at night (after 5:00 p.m.) until the temperature in the space reaches 85 degrees Fahrenheit (summer) and 62 degrees Fahrenheit (winter). Fan coil units, air handling units and exhaust fans will be shut down after 5:00 p.m. as well. The night setback temperatures will not be implemented in areas where cooler air is required (IT, medical supplies, etc.).

In addition to the temperature control policy, which will save approximately $20,000 over the summer, DAS/GSE has already implemented several improvements to the central chilled water system that provides cooling in the summer. DAS/GSE will conduct an additional study this summer to identify opportunities for further efficiencies.

By implementing energy control strategies such as these, we will all be contributing to the overall goal of reducing the State of Iowa’s usage of power, saving taxpayers even more money in the years to come.
