| HKUST | As-built BIM Model Verification Through Field Inspection and Laser Scanning: A Comparative Study | Report | 06/2020 | HUANG, Cong ZHOU Haoran LIU Hao |
BIM model is a prerequisite for the Operation and Maintenance (O&M) of sustainable buildings. Only after having a reliable BIM model can start O&M related work, such as space management and energy management, all these works needs to confirm the accuracy of the BIM model. In this project, the author conducted a verify of the BIM model to ensure that the model was correct before the O&M work started. This project first compared various survey methods, and based on their advantages and disadvantages, chose the laser scanning method and manual survey method for experiments. Then using two selected methods to do site surveying for HUKUST parking lot and LTK to SENG Commons. And the end, given survey recommendations for different types of as-built model verification based on the survey result. |

| HKUST | Incorporating Project Management Techniques in Building Information Modeling Projects | Report | 06/2017 | Hao WU Vincent Cheuk Hang TSE Chris Ho |
Building information modeling (BIM), which is becoming widely adopted by the construction industry for its superior efficiency and conveniences. However, due to great differences distinguished by conventional project construction process, traditional construction system cannot be perfectly exploited in BIM projects. Therefore, developing adaptive project management techniques are significantly essential to facilitate the BIM project implementation in the future. In this study, contractual framework, project delivery approaches and information management standard are studied. Based on the existing standards and feasible delivery and information exchange methods, comparisons and suggestions are given to improve BIM project management level from both technical and legal perspectives. In addition, potential BIM related claims with case study are also explored in this paper. Refer to the content investigated, some preliminary conclusions and recommendations are given for the purpose to achieve higher BIM project quality. | N.A. |
| HKUST | Simulation-based evolutionary optimization for energy-efficient layout plan design of high-rise residential buildings | Journal | -- | Gan, V.J.L., Wong, H.K., Tse, K.T., Cheng, J.C.P., Lo, I.M.C., and Chan, C.M. | Buildings consume 40% of global energy, in which residential buildings account for a significant proportion of the total energy used. Previous studies have attempted to optimize the layout plan of residential buildings for minimizing the total energy usage, mainly focusing on low-rise houses of a regular shape and having a limited number of design variables. However, layout design for high-rise residential buildings involves the complicated interaction among a large number of design variables (e.g., different types of flats with varying configurations) under practical design constraints. The number of possible solutions may increase exponentially which calls for new optimization strategies. Therefore, this study aims to develop an energy performance-based optimization approach to identify the most energy-efficient layout plan design for high-rise residential buildings. A simulation-based optimization method applying the evolutionary genetic algorithm (GA) is developed to systematically explore the best layout design for maximizing the building energy efficiency. In an illustrative example, the proposed optimization approach is applied to generate the layout plan for a 40-storey public housing in Hong Kong. The results indicate that GA attempts to maximize the use of natural-occurring energy sources (e.g., wind-driven natural ventilation and sunlight) for minimizing 30–40% of the total energy consumption associated with air-conditioning and lighting. The optimization approach provides a decision support basis for achieving substantial energy conservation in high-rise residential buildings, thereby contributing to a sustainable built environment. | Link |
| HKUST | Parametric modeling and evolutionary optimization for cost-optimal and low-carbon design of high-rise reinforced concrete buildings | Journal | 07/2019 | Gan, V.J.L., Wong, C.L., Tse, K.T., Cheng, J.C.P., Lo, I.M.C., and Chan, C.M. | Design optimization of reinforced concrete structures helps reducing the global carbon emissions and the construction cost in buildings. Previous studies mainly targeted at the optimization of individual structural elements in low-rise buildings. High-rise reinforced concrete buildings have complicated structural designs and consume tremendous amounts of resources, but the corresponding optimization techniques were not fully explored in literature. Furthermore, the relationship between the optimization of individual structural elements and the topological arrangement of the entire structure is highly interactive, which calls for new optimization methods. Therefore, this study aims to develop a novel optimization approach for cost-optimal and low-carbon design of high-rise reinforced concrete structures, considering both the structural topology and individual element optimizations. Parametric modelling is applied to define the relationship between individual structural members and the behavior of the entire building structure. A novel evolutionary optimization technique using the genetic algorithm is proposed to optimize concrete building structures, by first establishing the optimal structural topology and then optimizing individual member sizes. In an illustrative example, a high-rise reinforced concrete building is used to examine the proposed optimization approach, which can systematically explore alternative structural designs and identify the optimal solution. It is shown that the carbon emissions and material cost are both reduced by 18–24% after performing optimization. The proposed approach can be extended to optimize other types of buildings (such as steel framework) with a similar problem nature, thereby improving the cost efficiency and environmental sustainability of the built environment. | Link |
| HKUST | Holistic BIM framework for sustainable low carbon design of high-rise buildings | Journal | 06/2018 | Gan, V.J.L., Deng, M., Tse, K.T., Chan, C.M., Lo, I.M.C., and Cheng, J.C.P. | In high-density, high-rise cities such as Hong Kong, buildings account for nearly 90% of energy consumption and 61% of the carbon emissions. Therefore, it is important to study the design of buildings, especially high-rise buildings, so as to achieve lower carbon emissions. The carbon emissions of a building consist of embodied carbon from the production of construction materials and operational carbon from energy consumption during daily operation (e.g., air-conditioning and lighting). While most of the previous studies concentrated mainly on either embodied or operational carbon, an integrated analysis of both types of carbon emissions can improve the sustainable design of buildings. Therefore, this paper presents a holistic framework using building information modeling (BIM) technology in order to enhance the sustainable low carbon design of high-rise buildings. BIM provides detailed physical and functional characteristics of buildings that can be integrated with various environmental modeling approaches to achieve a holistic design and assessment of low carbon buildings. In a case study, the proposed framework is examined to evaluate the embodied and operational carbon in a high-rise residential building due to various envelope designs. The results demonstrate how the BIM framework provides a decision support basis for evaluating the key carbon emission sources throughout a building's life cycle and exploring more environmentally sustainable measures to improve the built environment. | Link |
