Advanced HVAC Systems for Improving Indoor Environmental Quality and Energy Performance Of California K-12 Schools, Project 2 Final Report: Thermal Displacement Ventilation.

Web Abstract: 
Serves as the final project report for Project 2, Thermal Displacement Ventilation (DV) in Schools, under California's PIER IEQ-K12 Program. Key outcomes included the following: 1)Two demonstration DV systems were installed, commissioned, and monitored in two classrooms; one in southern and one in northern California. 2)Results of the DV demonstration classrooms showed that significant energy savings are possible. 3)Other results of the DV demonstration classrooms showed improved IAQ and acoustics with acceptable humidity levels. 4)Teacher feedback was positive for the DV demonstration classrooms. 5)The demonstration classrooms confirmed that DV provides good thermal comfort for classrooms with normal ceiling heights (9 feet). 6)A supply of 1,100 cfm of 65-degree air is sufficient for most classrooms in California climates. 7)The use of a tuned VAV control strategy will optimize energy savings. 8)DV can be achieved today using a variety of HVAC system designs. 9)DV provides many compelling benefits including energy savings.
