Green buildings and sustainability

Design for energy, materials, water and life-cycle impact.

In depth

Aims: reduce energy, water, materials and waste; improve indoor quality and resilience. Strategies: passive design, high-performance envelope, efficient systems, renewables, low-carbon materials, daylight. Rating systems: LEED, BREEAM, Green Star, IGBC. Life-cycle assessment guides decisions.

Key points

  • Embodied vs operational carbon
  • Net-zero buildings
  • Cool roofs
Example

Passive solar orientation and shading cut cooling loads.

Why it matters

Sustainable design reduces energy, water and material use over the life of a building, so it lowers both costs and environmental impact.

Where this is used

  • Choosing a timber frame with low embodied carbon for a new office.
  • Designing a building envelope to reduce heating demand.
  • Specifying rainwater harvesting to cut mains water use.

Frequently asked questions

What is Green buildings and sustainability?

Design for energy, materials, water and life-cycle impact.

Why is it important to understand green buildings and sustainability?

Sustainable design reduces energy, water and material use over the life of a building, so it lowers both costs and environmental impact.

What is embodied carbon?

The greenhouse gas emissions from making, transporting and installing materials, which are counted over the building life.

What are the main green building schemes?

Schemes such as BREEAM, LEED and national rating systems assess energy, materials, water and health performance.

How is Green buildings and sustainability used in practice?

Typical applications include choosing a timber frame with low embodied carbon for a new office, designing a building envelope to reduce heating demand and specifying rainwater harvesting to cut mains water use.

What should I learn before Green buildings and sustainability?

Study "Building information modelling" first (topic 107 of 112 in Civil & Structural). It covers the groundwork this topic builds on.
