As toxic smoke spreads faster than flames, it often causes rescuers to lose their sense of direction until the oxygen runs out and prevent people from viewing an evacuation route hence inhale harmful smoke, which leads to regrettable incidents. Therefore, this research explores the smoke removal efficiency of a high-power Negative Ion Emitter Array (NIEA) in space. We created a 1:1 smoke chamber with high-concentration smoke to simulate the actual situation of the fire scene and installed high-power NIEA on the vertical or top surfaces of the smoke chamber. During the experiments, we recorded the changes in the concentration of negative ions, PM2.5, and the visibility to calculate the smoke removal efficiency of NIEA under different configuration modes. The expected goal of this research is that in the future, the NIEA could be pre-installed in the structures of buildings or temporarily mounted by rescuers along the escape routes to help people obtain cleaner air in a smoke-filled environment and to survive.","PeriodicalId":165618,"journal":{"name":"2020 IEEE 2nd International Conference on Architecture, Construction, Environment and Hydraulics (ICACEH)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124979452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the building can be shown to people who are not familiar with the project, and the design concept can be conveyed easily so that the people have a better understanding of the building. In this way, the purpose of visual marketing is achieved. Although virtual reality (VR) software has evolved considerably, it has limited interoperability with various software applications, which has hindered its adoption within the industry. Thus, this research explores how to integrate the interoperability of BIM models with rendering and VR software to improve the effectiveness of 3D visualization. The results demonstrate that in the process of integrating the BIM model with VR environments, model conversion, attachment of materials, and light and shadow settings require the greatest attention. After the importation of a BIM model into a VR environment, the faces of the model are too high to execute the system smoothly, limiting the model’s ability to completely supplant models constructed in VR environments. Therefore, modifying the BIM model through model reduction or textural modifications is necessary. The material of the model may also change during the conversion process, demanding that the model be rendered again in the VR environment. Furthermore, real-time light and shadow rendering may reduce system performance. However, the use of baking textures to paste lightmaps onto the model is an effective method of enhancing realism.","PeriodicalId":165618,"journal":{"name":"2020 IEEE 2nd International Conference on Architecture, Construction, Environment and Hydraulics (ICACEH)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126744807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
