Analysis And Research For The Main Technologies And Evaluation Comprehensive System In The Green Building

Along with the impenetration of sustainable development concept in the field of building.the concept of green building is increasingly affected by the society public concern. Green building main technical’s research is of no doubt, but setting up a green building evaluation system of objective, fair and systemic is also very important. Now.at home and abroad, the evaluation research of green building have a lot, but the technical measures and the cost benefit analysis are very weak. This paper expounds the content around the theme of the main technology and the evaluation system of green building, emphatically start from the green building evaluation system at home and abroad and main technical, to analyse detailedly for incremental cost and benefit of green building; Establish a evaluation comprehensive system based on cost benefit analysis, to quantitative analysis of cost benefit of the green building, and to perfect evaluation system of green building, and to promote the development of green building.Firstly, the paper put forward the green building’s now existing problems are based on the green building development situation at home and abroad, through the contrast analysis of the domestic and international green building evaluation system, sums up the similarities and differences of the green building evaluation system at home and abroad. Then the paper takes the green building evaluation system’s main technology as the research object, analyses the theoretical technology, provides the improvement measures, explores the green building technology and to make technology evaluation constantly improving and increasing. The paper is based on the theoretical analysis of the green building main technology, joining the cost benefit thought, to analyse detailedly for incremental cost and benefit of green building and to establish a evaluation comprehensive system based on cost benefit analysis. The paper practices the technical problems and evaluation comprehensive system of the green building engineering case in Nantong, and provides the corresponding technology solutions, and imitate analyses the wind environment and the sunshine and the daylighting. and optimizes the green building technology evaluation system, and through the green building technology optimization design to control the incremental cost and increase efficiency, and comprehensive evaluation the green building under the precondition of the low cost and low energy consumption and healthy comfortable. The innovation of the paper is breaking the status that the green building evaluation system only stays on the technical level at present, to analyse detailedly for incremental cost and benefit of green building, and to improve evaluation index system, and to integrate into the incremental cost, economic benefit, environmental benefit and social benefit, and to build comprehensive evaluation system of green building. The system can realize the evaluation, contrast and optimization of the green building, to reflect the true nature of green building, at the same time, to provide better platform for the development of green building.
