New and Underutilized Technology: Active Chilled Beam Cooling with Dedicated OSA Ventilation
The following information outlines key deployment considerations for active chilled beam cooling with dedicated OSA ventilation within the Federal sector.
In a chilled beam system, chiller energy is delivered efficiently to the zone via water. Air in occupied spaces is passed across the radiant chilled beam. Warmer water is used than in a variable air volume system, which helps reduce energy consumption. Small amounts of outdoor air are entrained into the larger supply of re-circulated air to provide the required ratio of fresh air.
Active chilled beam cooling with dedicated OSA ventilation is most applicable in buildings with more than 60,000 square feet of floor space.
Key Factors for Deployment
Active chilled beam cooling with dedicated OSA ventilation should only be considered during new construction or major renovations.
Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
