Competition brief for category B: IHL track

1. Choose 1 of 2 Questions

   1. What are the different ways to keep buildings cool naturally?

      • Examples:

        • Building orientation and window placement

        • Natural ventilation and cross-ventilation

        • Shading devices (overhangs, louvers, trees)

        • Green roofs and walls for cooling

        • Reflective materials (e.g. cool paint)

   2. How do buildings reduce carbon emissions?

      • Examples:

        • Alternative cooling technologies (e.g. hybrid cooling, passive displacement cooling, mix mode ventilation)

        • Energy efficient systems (e.g. air conditioning)

        • Renewable energy (e.g. solar energy)

        • Automatic controls and sensors (e.g. lighting, Occupant-Centric aircon systems)

        • Smart facilities/energy management (e.g. Building Management Systems, application of AI, Robotics and Automation)

        • Embodied carbon reduction measures / Sustainable building materials (e.g. Green Concrete, Green steel, Mass Engineered Timbre) and alternative materials (e.g. Carbon Mineralised Concrete, Recycled Concrete Aggregate, Ordinary Portland Cement)

        • Design for Maintainability
