Green Construction Evaluation Based On BIM And Semantic Technology

With the continuous improvement of social requirements on resources and environment,the greening process of production has become the trend of further development.As an industry with great impact on the environment and high resource consumption,the greening process of construction industry has been highly valued by the nation and enterprises.Green construction,as an important part of the whole life cycle of green building,has attracted more and more attention from the construction industry practitioners and relevant departments.It is an urgent process to improve the greening level of the construction process.At present,the nation has issued relevant green construction and evaluation specifications to guide the process of green construction.Due to the content of green construction specifications is relatively rough,the evaluation process of green construction is mostly qualitative while quantitative evaluation is relatively rare.In the process of quantitative evaluation,traditional manual evaluation method consumes a lot of time,manpower and cost,and is prone to error.Therefore,a more effective method is needed to improve the efficiency of evaluation.As a large amount of fragmented information is generated in the process of green construction,it is particularly difficult to rely on manual data collection and integration.The continuous development of BIM,semantics,internet of things,mobile communication and other technologies provides convenience for large-scale data collection and fragmented information expression.Therefore,the paper proposes a green construction evaluation method based on BIM,ontology and smartphone.In this method,the monitoring data collected by the sensor is combined with BIM model for real-time data display and warning on the BIM platform,and transmitted to the smartphone through WiFi module for real-time display of monitoring data.As a unified representation of fragmented information,ontology effectively integrates scattered information such as BIM site information,data collected by the sensor and green construction related specification data together,and realizes the reasoning process of green construction evaluation with the help of Protégé.On this basis,taking the standard for test method of mechanical properties on ordinary concrete(GB/T 50081-2002)as an example,the paper selects quantitative temperature and humidity indicators of concrete standard room as the validation indicators of the proposed method.The validation process realizes the display of monitoring data on BIM web client and pop-up warning,the real time display on mobile phone as well as the correct ontology reasoning result,showing the feasibility of the method.This method can effectively improve the efficiency of green construction evaluation and facilitate the intellectualization of the evaluation process.
