Key elements in the client’s requirements were the building’s sustainability and the use of local climatic conditions to drive passive environmental control. Bennetts Associates therefore designed the library to feature recycled rain water, low energy consumption and low embodied energy and the use of heavy concrete mass to achieve thermal stability.
Bennetts Associates also required a natural-ventilation system to assist mechanical systems and provide passive night cooling for the main library hall.
SE Controls provided a system of actuators fitted to low-level windows along the front façade and roof vents. They are driven open by the building-management system in response to signals from internal temperature sensors.
In the event of a fire alarm, all mechanical ventilation systems are shut down and passive systems driven closed. Battery back-up provides power if the mains supply fails.
