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
