As defined by the United Nations Brundtland Commission “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs” which can be broken down into the “three pillars” of sustainability – Environmental, Social and Economic as shown in the diagram below taken from the United Nations 2005 World Summit Outcome document.

Sustainable Construction

There are 4 Key factors to be considered with regards to a sustainable construction project :

  1. Energy : The use of ‘Alternative / Green Technology,’ reduction of energy consumption during and after construction..
  2. Waste : Reducing the amount of waste produced by using local products where possible and re-cycling as much waste as possible. All debris / demolitions / waste to be put into separate containers i.e. wood & rubble skips..
  3. Materials : Thought should be given to the type, source and manufacture processes of all materials to be utilised. Re-cycled materials should be used where ever possible, demolition materials where relevant..
  4. Pollution : This is linked to the all of the above. Using local materials reduces the actual carbon cost of the material. Nose pollution to be reduced by a variety of methods from dampeners to percussion equipment screening off where possible dependant on site constraints. Water pollution – risk assessments and method statements to be produced prior to works starting to make sure no ground water pollution occurs..
