With the acceleration of urbanization, the building energy consumption in China accounts for 20% of the total energy consumption, of which the depleting of residential energy accounts for 60.3%. A residential building-hall 6 in HKUST campus is chosen and energy consumption and daylighting is analyzed and optimized. After literature review and learning the advantages, disadvantages and application of different software about energy analysis, I choose some BIM-related software to conduct energy and daylight analysis and consumption, such as Autodesk Revit, eQUEST and Insight 360 based on Building Information Modeling (BIM).
For energy analysis, annual energy consumption is 795.2 mWh and half of it is space cooling.In our analysis, the illuminance levels of the building are 52% and 68% at 9 am and 3 pm respectively, which exceed the passing criteria, so daylighting of this residential building can meet the LEED requirement. The results in this project are useful for both building energy conversation and creating a comfortable living environment in future. |

With the global popularization of smartphones, which are equipped with various electronic sensors and hardware, the smartphones can collect useful information, such as location, light intensity, speed from the surroundings almost everywhere and anytime. The instant availability of the useful information has led to the formulation of a novel concept called context-awareness, which is developing computer programs to perform specific functions based on the acquired information. Location-awareness, which focuses only on collecting location information, is one of the future trends for building information modelling (BIM) development. The primary purpose of this project is to incorporate the idea of location-awareness to BIM in construction management and monitoring. To achieve this purpose, this project is objected to accomplish three main objectives, which are locating and analyzing the user current indoor position, acquiring and transferring the information in from BIM models to local devices and establishing the location-aware BIM framework on a viable and convenient platform. Thus, the location-aware BIM framework is developed as a mobile application named as “HKUST Library Helper”. The mobile application is not only equipped with Wi-Fi fingerprinting technology to support indoor localization, but also it is designed to provide different useful functions such as identifying rooms based on user position or by touch, extracting room information and creating and retrieving special notes and tasks for different rooms. |

Integration of BIM and GIS for City Planning |

With the popularity of 3D digital maps for computers and mobile phones, the development of 3D city models has grown substantially in the last decades. 3D maps can not only support navigation, but also allow people to perform city planning and architectural and engineering designs with the consideration of the surrounding environment. Moreover, many other advanced applications have been studied to be equipped in 3D models, like disaster management, noise and pollutant diffusion analysis and so on. Earliest research on 3D digital city models was in 1990s and now there are about a total number of 1252 3D digital city models worldwide already.
Since the early 1990’s, lots of researchers have conducted studies in creation, application and maintenance of 3D city models. The study results indicate that the modeling construction techniques and application exploitability has improved significantly in last decades. However, the level of development of existing models varies widely in view of geographic locality (either city or country), creation time and many other factors. A standardized evaluation framework of the existing 3D city models is still in need.
Based on the purpose of setting up an evaluation framework, this review work was conducted. Mainly through literature review and searching on project websites, we collected original sources of more than 70 projects of 3D city models and 23 are chosen for detailed study and analysis. These city models are mainly categorized in four continents (North America, Europe, Asia and Oceania) and in four aspects (model coverage, modeling technology, application and maintenance).
To the point, a preliminary model estimation method is created, considering the maturity of five aspects during modeling procedures, i.e. data capturing, data processing, data storing and managing, data presenting and data updating. According to the evaluation framework, city models can be categorized into four maturity levels as 3D GIS as a Scene, 3D GIS as a Service, 3D GIS as an Infrastructure and 3D GIS as a Platform. Finally, based on the analysis results, some limitations of 3D city models in current situation are summarized, and recommendations of possible resolutions are presented correspondingly. |
