What is sustainable building?
Sustainable or green building construction aims to embody the principals of sustainable development i.e. environmental protection, economic development, and social development, in the siting, design, building, maintenance and occupation of buildings.
Sustainable buildings are designed and constructed to high environmental standards and thereby; minimise energy requirements, reduce water consumption, use materials which are of low environmental impact e.g. low embodied energy and resource efficient, reduce wastage, conserve / enhance the natural environment and safeguard human health and wellbeing.
For example considerations for Sustainable Housing would include:
Environment: conservation and enhancement of the site ecology / biodiversity.
Energy: minimising energy consumption, high levels of insulation, building orientation to maximise solar gains and shelter from prevailing winds, maximising daylighting, energy efficient lighting and appliances,
Water: consumption and water efficiency, rainwater reuse, water efficient appliances, minimising and attenuating surface water run-off to prevent flooding and pollution.
Transport: Location near to public transport routes, proximity to amenities and places of work, space for home working - e.g. home office to reduce commuting.
Materials: use of long-life materials of low environmental impact during extraction, manufacture and use, avoid using toxic materials and those from non-renewable and non-sustainable sources, use of materials which can be reused / recycled, use of locally produced materials to reduce transportation requirements, use of recycled materials.
Health and wellbeing: use of non-toxic finishes and materials, natural daylighting, freedom from noise, indoor air quality, private outdoor space, green space, design for community and 'sense of place', integration with the surroundings / landscape.
Affordability: minimise the cost of ownership - if it isn't affordable - it cannot be truly sustainable, flexibility and adaptability to meet the changing needs of present and future occupiers.

Sustainable buildings assessment and standards
- Code for Sustainable Homes - (UK Communities and Local Government)
The Code is an environmental assessment method for new homes based upon Building Research Establishment’s Ecohomes. It contains mandatory performance levels in seven key areas (energy and CO2 emissions, water, materials, surface water run-off, waste, pollution, health and wellbeing, management, ecology) and aims to encourage continuous improvement in sustainable home building. Search results for Code for Sustainable Homes - from www.gov.uk, lists Technical Guidance, Case Studies, etc. More information is available on the BREEAM website.
CarbonLite, an AECB initiative, provides tools and knowledge to create low-energy buildings. It is a practical step-by-step guide for practitioners involved in the design, construction and use of low-energy, low-CO2 emissions buildings.
