Bedford Campus Centre, University of Bedfordshire, UK
The building juxtaposes several discrete environmental design strategies, all naturally driven. In the theatre fresh air is supplied into the plenum formed below the seating rake through banks of acoustic absorbers. The plenum is built in honeycomb blockwork to provide thermal mass. Air is exhausted above a full lighting gallery level, via acoustic boxes, into a cruciform exhaust object, each orientation separately controlled. The building is over twice as airtight as regulatory minimum and full heat load commissioning has been very encouraging. Night time ventilation is an important part of the summer comfort strategy.
