Explore the principles of sustainable design in architecture, planning, and the built environment, including concepts such as energy efficiency, passive design strategies, green building materials, and environmental impact assessments.
Sustainable Design Principles
- Introduction
- Sustainable design: creating buildings and spaces that minimise environmental impact while meeting human needs.
- It balances environmental, economic, and social goals across a building's life.
- Core Principles
- Energy efficiency: reducing demand through insulation, orientation, and efficient systems.
- Resource conservation: using renewable, recycled, and low-impact materials.
- Minimising waste, water use, and pollution throughout the life cycle.
- Key Strategies
- Passive design uses sunlight, shade, and natural ventilation to cut energy use.
- Renewable energy such as solar and wind reduces reliance on fossil fuels.
- Water harvesting and greywater recycling conserve resources.
- Assessment and Standards
- Rating systems such as LEED and BREEAM benchmark building performance.
- Life-cycle assessment: evaluates impacts from material extraction to demolition.
- Embodied carbon and operational carbon are both considered.
- Benefits
- Lower running costs and reduced greenhouse gas emissions.
- Healthier indoor environments and improved occupant wellbeing.
- Greater resilience and long-term value for communities.
