Dedicated Outdoor Air System with Active Chilled Beam Design
With alternatives considered, the proposed mechanical redesign will concentrate on implementing a dedicated outdoor air system (DOAS) with active chilled beam (ACB). This system will be evaluated with regards to energy consumption, thermal comfort, and air quality. In addition to design considerations discussed in previous technical reports, the primary air system for ACB must adhere to the following criteria (Trane, 2011):
-
Each space must receive at least the required amount of outdoor air according to ASHRAE Standard 62.1.
-
To avoid condensation forming on the chilled beams, air must be dry enough to offset the space latent load while maintaining a low enough indoor dew point.
-
Sufficient air must be delivered to induce airflow that offsets the space sensible cooling load.
CM Breadth
Installation and maintenance procedures for active chilled beam will be investigated. Because active chilled beams do not have filters within their construction, maintenance and cleaning of the beams is important to maintain occupant health.
lighting Breadth
The use of LED fixtures instead of the existing flourescent fixtures will be investigated, with the intent to decrease the overall wattage use of the building.
