Life Cycle Analysis Essay -- science

heart Cycle abbreviationA buildings purlieual invasion extends from global factors, such as ozone depletion, to the quality of the milieu inside the property. These impacts arise from decisions made at all stages of the buildings life, including materials manufacture, site selection, design, construction, commercial enterprise and ultimately demolition. Source Greener Buildings, environmental Impact of Property - Stuart Johnson. A piece of music On environmental Life Cycle Analysis ( L.C.A. ) Introduction The globe is becoming an ever more environmentally vigilant society and wring by governments, NGOs ( Non - government organisations ) and the general public is being put on all aspects of labor to become more Green. The construction industry has a great impact on the environment both at the construction stage and the buildings future life, as stated in Stuart Johnsons enterprisingness statement above. As with all industries the construction industry as a whole has and con tinues to devise ways in which the relationship between the build and the natural environment can improve. One such development is the proficiency of Environmental Life Cycle Analysis. Life Cycle Analysis Life calendar method of birth control analysis is used to explore the life cycle of a building material. It is computer based and its methodology was real by the society of Environmental Toxicology and Chemistry ( SETAC ). The life cycle analysis will showing the environmental impacts of different materials at different stages of its life from the materials extraction finished 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 esta blishing * hazardous contents * risks to occupants, trades people and the general environment * ecological degradation from extraction of raw materials * recycled content * pollution from manufacturing * carbonic acid gas released during manufacturing and embodied energy * transport implications * durability ( life to replacement ) * cycle 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 have for environmental life cycle analysis is great if the continuing tumble of the environment is to be slowed. Firms within the construction industry must handgrip their hands 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 desi gn for the long endpoint and not just for short term gain.
