    How Students Lose Marks (Examiner Pitfalls)
    Pitfall: Students often confuse 'sustainable' with 'recyclable' and fail to consider the full lifecycle of materials.
    ❌ Weak Answer (Loses Marks):Sustainable materials are those that can be recycled.
    Example improved answer:Sustainable materials are those that have a low environmental impact throughout their entire lifecycle, from extraction and processing to use and disposal. This includes considerations of embodied energy, renewability, and the ability to reuse or recycle at the end of the building's life.
    Examiner Tip: Always refer to the whole lifecycle of a material, not just its recyclability, to demonstrate a deeper understanding.
    Pitfall: In design questions, students often forget to justify their choices with reference to sustainability principles.
    ❌ Weak Answer (Loses Marks):I would use solar panels because they are good for the environment.
    Example improved answer:I would incorporate solar panels into the design to generate renewable energy on-site, reducing the building's reliance on fossil fuels and lowering its carbon footprint. This aligns with the principle of reducing operational energy use and promoting renewable energy sources.
    Examiner Tip: Always link your design choices to specific sustainability principles such as reducing carbon emissions, conserving resources, or improving energy efficiency.
    Step-by-Step Worked Solutions

    Question: A building uses 20,000 kWh of energy per year. If 30% of this energy is from renewable sources, calculate the amount of non-renewable energy used in kWh.

    1. 1.Step 1: Identify the total energy use: 20,000 kWh.
