“Sustainable development intends to ensure that the needs of the present generation will be met without compromising the ability of the future generation to meet their needs” (Brundtland report)

Sustainability is ‘striving for sustainable development through a combination of sound, environmentally aware, functional and economically viable planning, design, construction and management’. Sustainable construction generally has four perspectives: flexibility, integrated chain management, energy saving/alternative sources and promoting quality.

ABT advise their projects from the following vision on sustainability:

• Sustainability must be in design, construction and use phase of buildings as obvious as functionality, safety and cost efficiency.
  
• Sustainable buildings are the result of an integrated designprocess, where solutions are devised from different perspectives, an approach that fits ABT.
  
• Reuse and upgrading of existing buildings increase the sustainability of the built environment.
  
• As buildings become more and more energy-neutral or energy suppliers, the focus have to be stiffed to material savings and use of sustainable materials.
  
• Using advanced computational methods and smart design, material savings, lower construction costs and higher sustainability will result.
  
• Sustainable buildings generate long term returns by energy conservation or production, reuse, salvage value at the end of lifetime and a better quality of life.
