This presentation will provide a system level overview of Sensible Cooling Terminal units, Dedicated
Outside Air units, and the potential chiller plant configurations that feed those components. As
buildings are designed for lower energy use, the resulting reduction in cooling loads presents an
economically feasible opportunity for systems that use zone-level, sensible-only cooling equipment.
These systems combine a dedicated outdoor air system with chilled-water, sensible-cooling terminals to
deliver a flexible, energy efficient solution to provide comfortable spaces and simplify maintenance.
