Frederick County Public Schools - WiFi Thermostats

Frederick County Public Schools conducted a pilot study in 2010 to demonstrate the value of intelligent controllers for portable classrooms that learned occupancy patterns and modified HVAC operating schedules accordingly. When compared with a baseline portable classroom, the controller could produce a 30 percent energy savings. Because funding was not available to procure hard-wired intelligent controls, the school system found a creative alternative. Once Wi-Fi was installed throughout the school system, a new possibility arose: inexpensive Wi-Fi thermostats. We can now remotely control portable classrooms individually, in groups, or in total. While these inexpensive thermostats are not as robust as the more expensive alternative, they have produced a 20 percent cost savings in electric use.
