The latest innovations in commercial construction are targeted to improve environmental performance of a building throughout its lifecycle. Chilled beams have become a more common design strategy for controlling the perimeter zone and sometimes the interior zones of many buildings. In a chilled beam, water pipes pass chilled and hot water through a heat exchanger or a “beam”, which is then capable of cooling or heating air delivered to a space. The energy efficiency and improved capacity of water cooling and heating coupled with the ability to condition skin loads before they affect the occupant have been a strong catalyst to the growth in popularity. Tate has introduced a new take on the traditional ceiling mounted chilled beam that offers the same benefits while removing some of the negatives associated with overhead chilled beams.
In-floor Active Chilled Beams
- Handles perimeter heating and cooling loads
- Chilled water is delivered safely below the floor
- Gain the full energy efficiency advantage of water for cooling and heating by conditioning at the source of the load
- Preconditioned plenum air delivered to the chilled beam will not produce condensate
- Ability to use water below dew point and control condensation
- Easily manage shoulder season conditioning
- Gain advantages of stratified airflow vs. overhead chilled beams
Typical In-Floor Chilled Beam Design
In-floor chilled beams allow for complete seamless integration. The beam can be installed as a continuous linear grille along the perimeter or segmented only where needed. Using chilled beams reduces the number of diffusers in the perimeter zone and eliminates the need for equipment to be installed under floor panels. With in-floor chilled beams you gain all the aesthetic benefits of a raised floor including the elimination of the drop ceiling and the reduction in service distribution space for expanded daylighting and access to views.

In-Floor Active Chilled Beams Improve UFAD
Overall, placing a chilled beam at the perimeter can simplify the design of a UFAD system by eliminating the concern for thermal decay. Typical UFAD designs use spider ducting to deliver air within 50 feet of the perimeter so it can be delivered to the space before it warms under the floor. The In-Floor Active Chilled Beam solves this by bringing chilled water to cool air directly at the perimeter of the building. Using chilled beams in place of perimeter fan powered boxes under the raised floor allows furniture and partitions to be placed freely in the building without the concern for maintenance access to equipment. Aesthetically, the In-floor Active Chilled Beam reduces the quantity of visible diffusers within the perimeter zone and creates a cleaner appearance. By using segmented or continuous linear grilles along the perimeter of the building the in-floor chilled beam seamlessly integrates into the design of the space.
