MSCBs are part of energy strategy for new university building
Comfort cooling using an absorption chiller and lighting are provided by Trox multi-service chilled beams in this new building at Southampton University.
Multi-service chilled beams form a key part of the low-energy solution for a new building at Southampton University. Supplied by Trox for the Treble E (engineering, entrance and education) building, the beams are supplied with chilled water from an absorption chiller with a flow temperature of 14°C and a return of 17°C. The chiller is linked to the recently completed site-wide district-heating and CHP plant. Mark Turner, the university’s energy manager, explains, ‘After the project team identified the need for mechanical cooling of this intensively serviced building, the next stage was to ensure that this was provided in the most energy-efficient way possible. MSCBs operate at a high chilled-water temperature, meaning smaller temperature gradients. Linking these to an absorption chiller has ensured the best possible CoP of the plant, thereby minimising carbon emissions.’ The MSCBs also integrate lighting complying with the LG7 lighting code, as the exposed soffit is unpainted, self-finish reinforced concrete. Trox Design Bureau worked closely with one of its strategic lighting partners, the consulting engineer and the architect to ensure that the required overall lighting effect was achieved. Architect Nick Hacking of John McAslan & Partners says, ‘The chosen aesthetic for the chilled beam was based on a similar “angular” format that has previously been successfully utilised on another university project where Trox also supplied and installed chilled beams.’ The MSCBs were made off site and fully tested before installation.
