The locally fabricated precast concrete envelope presents a sculptural interpretation of the originally expressed modernist structural grid; this exterior-insulated, high-performance rainscreen assembly both creatively preserves the campus’ design heritage and contributes to substantial improvements in energy-efficiency and occupant comfort. In contrast to the original building, the renewed facility is welcoming, accessible and inclusive, with a relocated ground level entrance and generous visual and spatial interconnection that promote natural wayfinding.

Corridors flow seamlessly into Informal Learning Spaces (ILS), fostering connection and collaboration. Classrooms and labs feature flexible, adaptive design that accommodates cutting-edge technology and world-class research. The retrofit approach, while challenging, offered significant benefit, avoiding the ecological impact of wholesale redevelopment and achieving substantial carbon savings through retention of 73% of the original structure. The LEED Gold building leverages passive and active strategies – including a new multi-storey passive-assist light and air shaft, energy-recovery-equipped air source heat pump, operable windows, and abundant daylighting – to meet ambitious client performance targets, achieving an estimated 56.15% reduction in energy intensity over a new-build reference building.

The MacLeod project is a case study for institutional renewal, creating a sustainable, resilient facility that supports first-class research and learning in a dynamic, inclusive and accessible setting.
