Building Envelope and Structure

Facade

To improve the efficiency and performance of the building envelope, the existing cladding will be replaced with high-performance insulated panels, dramatically improving thermal performance and reducing heat loss. This intervention also provides the opportunity to reinstate the original 1978 design intent, restoring the appearance of the distinctive profiled façade panels.

Roof

The existing roof has degraded and reached the end of its serviceable life. It will be replaced with a new insulated roofing system, improving weatherproofing, durability and long-term performance. Integrated access systems will allow safe maintenance and cleaning, while photovoltaic panels incorporated within the roof build-up will generate renewable energy on site, supporting the university’s net-zero ambitions.

Glazed End Walls 

The single glazed annealed glass end walls will be replaced with highperformance insulated glass panels, improving energy efficiency while preserving the expansive views across the surrounding campus landscape. New structural glass fins and power-assisted doors will enhance safety and accessibility, strengthening connections between the inside and outside. 

These alterations to the building’s envelope are expected to halve the amount of energy required to operate the building, significantly reducing carbon emissions.

Structure

The movement joints within the existing structural frame prevent stress from accumulating in the cladding or membrane and help to eliminate microcracking that leads to water ingress over time. Replacement of the movement slip plates together with localised repairs and repainting are proposed, ensuring that deterioration is prevented.

The existing building has a number of leaks
