SAS International passive chilled beams were installed above 2,330m2 of SAS130 lay-in metal ceiling system to provide a high quality office finish at Howbery Business Park, Oxfordshire.

The building was designed with sustainability in mind using environmentally friendly technology including comfort cooling provided by chilled beams using a borehole.

The use of passive chilled beams is an innovative approach providing the building with energy efficient cooling in conjunction with a displacement ventilation system. The combination of passive chilled beams, displacement ventilation and a geothermal bore helped achieve an ‘Excellent’ BREEAM rating.

Passive chilled beams are a flexible, low-energy choice for both new-build and refurbishment projects. Natural convection drives warm air up through the occupied space. This is drawn through the chilled beam, is cooled and returns to the occupied space. Passive chilled beams produce outputs in the region of 300 watts per metre length (W/m) and active chilled beams can achieve cooling outputs of 500W/m.

Chilled beams use water as a heat transfer method and offer a practical alternative to conventional air conditioning systems. Chilled beams work by natural convection and are to a large extent self-regulating. This makes control strategies simple and very cost effective.
