Costing Systems And Engineering Practices On Building Outer Wall Heat Preservation

This paper displays the technical differences between the building outer wall heat preservation at home and abroad by analying the development of heat-insulating at home and abroad. This paper study on the outer wall heat preservation, inner-heat preservation and self-heat preservation by analying and comparing the technical characteristics of each system,sum up the problems and solutions in design and construction to avoid the quality problems.This paper study on the heat engineering calculation to give the major factors to influence the project, throughing the analysis and introduction of shape coefficient to give the influence on the design standard for energy efficiencyThe paper Links engineering practices to sum up the energy saving system and gives advices to the choose of building outer wall more systematic and theorise to avoid the loss of the adverse selectionThis paper gives the development direction of the building outer wall heat preservation throughing the whole study.
