Life Cycle Analysis Essay -- science

Life round of golf AnalysisA buildings environmental impact extends from global factors, such as ozone depletion, to the quality of the environment inside the property. These impacts arise from decisions make at all stages of the buildings life, including materials manufacture, site selection, design, construction, occupation and ultimately demolition. Source Greener builds, environmental Impact of Property - Stuart Johnson. A Report On Environmental Life Cycle Analysis ( L.C.A. ) Introduction The world is becoming an ever more environmentally vigilant society and pressure by governments, NGOs ( Non - government organisations ) and the general public is organism put on all aspects of industry to become more Green. The construction industry has a great impact on the environment some(prenominal) at the construction stage and the buildings future life, as stated in Stuart Johnsons opening statement above. As with all industries the construction industry as a whole has and continues t o devise ways in which the relationship between the built and the natural environment can improve. One such development is the technique of Environmental Life Cycle Analysis. Life Cycle Analysis Life cycle analysis is used to explore the life cycle of a building material. It is data processor based and its methodology was developed by the Society of Environmental Toxicology and Chemistry ( SETAC ). The life cycle analysis will show the environmental impacts of different materials at different stages of its life from the materials extraction through processing, manufacture, use, maintenance and disposal. An example of the type of software used in L.C.A. is SimaPro 3.0 which was developed by PRe Consultants in the Netherlands. SimaPro provides information on the generation of pollutants and the following environmental effects of different materials and is measured using eco-points. The main issues of life cycle analysis for materials consist of establishing * hazardous contents * ris ks to occupants, trades spate and the general environment * ecological degradation from extraction of raw materials * recycled content * pollution from manufacturing * CO2 released during manufacturing and embodied energy * transport implications * durability ( life to reserve ) * recycling and disposal Source Specifying for Greener Buildings - Stephen Curw... ...s 1993 ( CHIP ) HMSO * Specification for Environmental Management Systems.

Conclusion It is clear to see that the learn for environmental life cycle analysis is great if the continuing decline of the environment is to be slowed. Firms within the construction industry must hold their custody up and accept responsibility for the huge environmental impact caused by the building, and support the full life cycle analysis of as many materials as possible, they also need to design for the long term and not just for short term g ain.
