Univ logo UKACC PhD Presentation Showcase Slide 2 Introduction About 200 million passengers transit UK airports every year resulting in huge demands for energy About 200 million passengers transit UK airports every year resulting in huge demands for energy Airports are among the greatest energy consuming buildings – huge opportunity for savings Airports are among the greatest energy consuming buildings – huge opportunity for savings Airport environment systems are run on full schedules and setpoints are not varied according to external conditions and passenger flow Airport environment systems are run on full schedules and setpoints are not varied according to external conditions and passenger flow This research developed a supervisory controller which ensures comfort setpoints availability during occupancy and setback in other times for passenger-only airport spaces. This research developed a supervisory controller which ensures comfort setpoints availability during occupancy and setback in other times for passenger-only airport spaces.

This Fuzzy Supervisory control mimics airport building operator by varying setpoints in accordance to passenger flow and external conditions. Early simulation results shows that up to 50% energy savings is possible using this control system Early simulation results shows that up to 50% energy savings is possible using this control system The controller is still being tested through offline simulation The controller is still being tested through offline simulation
