My company, Bovis Lend Lease, is potentially going to be involved in the design & construct of a high rise ofice building employing active mass ceilings (high temperature CHW through the structural slab exposed to the occupied space below) in combination with underfloor air using 19C or so air supplied through Krantz type swirl diffusers. Being in Sydney Australia the focus is on cooling rather than heating although perimeter heating would be provided via a separate underfloor air AHU or trench heating etc.<BR>

The system offers IEQ and energy efficiency advantages in theory ... though there are a number of fitout and construction challenges.<BR>

We are aware of numerous German and Swiss built examples of this type of system, but understand the Canadians have been applying this type of system in places thus I am hopeful this forum can assist with my query. I would appreciate any information on buildings in operation or construction with active mass cooling / ceilings outside of Germany and Switzerland. Building names and locations as a minimum, but any other information would be kindly received ...<BR>
