The HVAC Design Process Optimization Based On Green Building Evaluation

Today,when the whole society calls for the concept of ecological sustainability,the green building in our country is developing rapidly.In the whole construction project,the indicators of the whole life cycle of the project need to be measured by green building evaluation,so it can be called industry standard.The design stage is the basic stage of the construction project,as a high energy consumption HVAC major in the design process can meet the requirements of green building evaluation is particularly important.However,in practical work,based on various reasons,there are some conflicting and insufficient factors between the traditional HVAC design process and the green building design.This thesis is devoted to analyzing the key factors in the green HVAC design,and optimize the traditional design process.This thesis is based on the evaluation of green buildings in China,through literature reading,combined with design practice to determine the relevant factors between HVAC specialty and green building design,design questionnaires and send them to HVAC designers for data collection.The weight of the recovered data is analyzed by using the improved AHP.Combined with the problems found by HVAC designers in engineering practice,the key factors affecting the design process are found,and the IDEF0v(ICAM DEFinition)method is used to model and optimize the design process.In order to meet the score requirements of HVAC design in the evaluation of green buildings in our country.The main conclusions of this thesis are three points.(1)In the green building HVAC design process,there are widespread cases of design guidance lag,lack of collaboration awareness,and ambiguous concepts.(2)Through analytic hierarchy process weight analysis,energy saving and the energy utilization,indoor and environmental quality are the key factors that HVAC designers consider in the green building design.(3)Based on the IDEF0 v method to optimize the HVAC design process,the actual case is verified to prove the practicality of the conclusion and feasibility.The thesis concludes with examples and presents shortcomings and prospects.
