| With the goal of saving energy over the 90.1 baseline (Overhead VAV), many architects are challenging mechanical engineers to provide alternate system designs. Chilled Beams have a potential to save energy, and meet these needs. Chilled Beams and dedicated outdoor air terminals can be attractive methods of delivering outdoor air at low potential energy cost while reducing building space requirements for mechanical system components. In order to meet the thermal comfort expectations of building occupants, designers must be aware of the conflicts between first costs, occupant productivity and life cycle costs. The presentation includes the following: |
