HKUST Integrating BIM and Internet of Things for Building Facility Management and Energy Management Report 06/2019 Yaoming HU
Bonan Zhang
This project studies sensor location determination in a complex conference room as a part of Smart HVAC system. It describes the background of HVAC system and how the system can be upgraded as a smart system, automated system, to save energy. The project mainly studies the methodology and uses some factors in IAQ, indoor air quality, to illustrate possible locations for sensor placement. In this project, Autodesk Revit is used to build a BIM model of a conference room. The building of BIM of the room is important since it will reflect the true structural setup of the room. Autodesk CFD is then introduced to run simulations. For CFD simulation, materials and boundary conditions are applied to the model in order to run simulations that can reflect distribution as realistic as possible. In the CFD simulations, some major IAQ factors such as, temperature, air velocity, thermal comfort, CO2, VOC (formaldehyde) and dust (PM 2.5) are predicted in the environment. To analyze the temperature distribution, different numbers of people are introduced to examine the difference of heat distribution due to number of people. Pollutants are examined using assumed values according to average emission values. The goal is not to determine whether or not the room is polluted but the distribution of pollutants inside the room. Eventually, the results of all simulations are collected and analyzed to determine the areas with high density of heat, pollutants where those high concentration areas are the prior locations sensors have to monitor. It is concluded that the simulation of air movement, heat, pollutant distribution, etc. is useful methodology to determine sensor locations. With the sensor placed in correct locations, HVAC system can run with higher efficiency and prevent hazardous environment. N.A.
HKUST BIM-based Daylighting and Energy Analysis on the HKUST Campus Report 06/2019 Quazi Samira Rahman Building Information Modelling (BIM) based simulation models have been consistently used to automate prolonged building performance modelling processes such as thermal comfort assessment and energy analysis, enabling fast acquisition of results. Recent studies indicate that the demand for sustainable building facilities with minimal environmental impact is growing day by day. BIM is foreseen as a savior in terms of technology to unravel laborious engineering problems in a short span of time and analyse the conditions in a given space comprehensively as well as determine efficiency of built environment. This study presents how building information modelling can be utilized to address thermal comfort and energy efficiency in buildings in the operation phase, greatly contributing to achieving optimized solution. The study primarily deals with multi physical investigation on performance assured by ventilating system in supplying air quality and determining the potentials of comfort improvement and energy savings for the control of ventilation rate by proposing optimized method for relocating supply air duct. The focus of this thesis is limited to IAS lecture theatre at HKUST with respect to current set points for the supply air temperature. N.A.
HKUST Comparative Study on Global BIM Standards Report 06/2019 Xiaoyang TANG In the recent decade, the Building Information Model (BIM) is developing at an unbelievable high speed worldwide. Just two years ago, China has published its first BIM standard to unify the BIM project process. In this essay, several China BIM standards including GB/T 51269, GB/T 51212 and GB/T 51301 are compared with other released global BIM standards according to its category. Mainly, there are three types of standards in the world, which are the International Framework for Dictionaries (IFD), Information Delivery Manual (IDM) and Industry Foundation Class (IFC). First, two types of standards are focused, which IFD will compare the GB/T 51269 with OmniClass from America, while IDM will compare the GB/T 51212 and GB/T 51301 with CIC BIM standard from Hong Kong, Singapore BIM Guide Version 2 and PAS 1192.2 from the UK. In order to compare these standards with a logic method, CIC BIM standard’s structure is chosen as the example for IDM while IFC follows GB/T. All the sections mentioned in the standards have been compared to summarize the advantages and disadvantages of China BIM standards.

After compared all the standards, it could conclude that the GB/T standards are general information for most sections, which means it is suitable for most types of BIM projects. However, several sections are missing compared with other global BIM standards. For example, one of the most important BIM section called Individual Discipline Modelling is missing in any GB/T standards. Therefore, there is still room for improvement in the future.

Building Information Modelling (BIM) has had a profound effect on the construction industry. It has greatly improved coordination among stakeholders, enhanced productivity, and increased profits. However, risks and hazards are also increasing with the growing complexity and scale of AEC projects, and the adoption of BIM technology will also place barriers and obstacles even though the technology has been proven to show its various benefits throughout the project lifecycle. Firstly, a literature review is conducted to identify risks and benefit of implementing BIM. twenty-one risks are identified and classified into three categories: Technology, Contract, and Project. Secondly, some suggestions for eliminating the increased risks are given. This paper will focus on how to implement risk management in BIM project against the recent technological background, and some related measures of mitigation, such as insurance, will be discussed.

Zhang Yini
In contemporary, the requirements for promoting facility management efficiency is increasing. The traditional facility management may cost too much workforce, too much energy and money. In addition, it cannot meet people’s demand of sustainable development and the requirements of offering a comfortable environment indoors.

With the rapid development of BIM and IoT technology, we would like to make use of those technology to solve this problem. In this project, based on optimizing the facility management of student residual building which located at HKUST, some superficial attempts are made. In the project, the current situation of traditional facility management and the development of BIM and Internet of Things technology are firstly studied. Then, we introduce the application of BIM and IoT technology on facility management, and its benefits as well as weakness. Then we compare some famous and widespread brands products in BMS field. Finally, this project concluded some possible improvement and some future work. Also, we describe the picture of applying this application in realistic which can show the great potential of applying BIM + IoT technology in future facility management.

Nowadays, BIM has transformed architecture, engineering and construction. However, the great potential of BIM is to provide accurate, timely, and relevant information not just during design and construction for a single building, but also throughout the lifecycle of an entire portfolio of facilities, such as the facility management. It has many competencies and plays an important role in the total life cycle of the building. The process of facility management need the support of lots of information which could then be provided by BIM model. Therefore, BIM model plays an important role in facility management.

BIM models are usually created from designed information which is called as-designed BIM model. However, there are lots of existing buildings do not have BIM model when they are built. For new buildings, there are also many changes may occur during construction, and the as-designed models could not present the real conditions. Therefore, an as-build BIM model may be needed to help the visualize and renovation of the project. What’s more, the current method for creating BIM models are mainly concentrated on regular buildings. However, more and more architect would like to design building with irregular buildings. Therefore, a new method should be used to create BIM model for irregular buildings.

This project aims to find a semi-automatic method to create BIM models for irregular building which could be applied for facility management. It takes a real project in industry as example and try to build the BIM model for a sky light bridge located in Hong Kong Airport by a combination of different software. This method firstly extracts the geometry information for each member from the point cloud data that gain from laser scanning. Then, it convert those conditions into BIM model with the help of Dynamo and Revit.
