ADVANCING NET ZERO IDEAS COMPETITION 2021 E-BOOK 1 Passive design with natural ventilation and buffer zone The Future Building category • Side-cored design & optimised building orientation • Self-shading building mass • • First principles approach to passive building design - orientation and components of tower Passive Measures, Minimise conditioned spaces: Outdoor space provided for working & meeting, Perimeter outdoor zones on each floor, Large communal outdoor spaces throughout tower, Encourage external meeting/ working/ living etc • Minimised AC area, decentralised AC system, natural ventilation optimisation • Natural ventilated common area • Natural ventilation • Promote natural ventilation for all enclosed spaces Reduced distances on each level to improve natural ventilation • Operable windows for natural ventilation • Daylight optimisation • Permeable pedestrian zone • Side core with solar chimney • Adaptive comfort approach • Microclimate envelope • Biomimicry • Twin Tower with Green Atrium • Wind corridors with operable shutters • Building permeability; permeable podium design • Setback on west elevation as thermal buffer • Foldable facade • Heat stack effect • Wind catcher The Existing Building category • Bi-metal (Daylight Strategy) • Cross ventilation • Free Cooling / • Natural Ventilation • Dynamic External Shading • Biomimicry • Hybrid ventilation Minimise indoor space to convert that into naturally ventilation space with natural lighting using sun pipe • Flexible openable window design 2 Structural efficiency and choice of materials The Future Building category The Existing Building category • Design for deconstruction and recycle • Low carbon structural design • Hybrid timber and steel superstructure frame • High performance fabric • Lightweight concrete with cement replacement • Light weight cross laminated timber as slabs • Timber- structured roof and canopy • Optimisation on structural elements • Optimisation to reduce structural load at top • Timber MiC • Structural elements with recycled contents • Reduction in churn, wasteful user fit outs • Cement free reinforced concrete substructure • Selective approach to use and procurement of Façade materials • Flexible partitioning • Radiant cooling system to reduce building mass • Additions to building consist of timber, recycled, and re-usable components, minimising total embodied carbon and providing a feasible circular model throughout three development phases to 2080 19
