HKUST Analysis and Evaluation of Green Building Features Using Building Information Modeling FYP 06/2015 LO Lok
Kwok Hoi Ling Helen
The number of green buildings is growing rapidly worldwide and the construction of green building can be facilitated by Building Information Modeling (BIM), which also becomes popular in recent years. At the same time, increasing number of new and current buildings are getting certified as green buildings by energy codes.

The project aims to study the green features of the HKUST Jockey Club Institute for Advanced Study (IAS) building as it is designed to reduce energy consumption with daylighting. Lighting and space cooling are the two major annual electric consumption by while spacing heating is the major annual fuel end use. The energy simulation results reveal that similar simulation engine generates similar results.

Alternative designs are created to further improve the energy saving efficiency of the IAS building and are compared with the original IAS building. The best orientation for the IAS building is to be rotated 150o clockwise from the original position. The building should also have occupancy and daylighting sensors and controls installed. The curtain walls should be replaced by translucent wall panels (U-0.10, SHGC 0.06, Tvis 0.04). The results agrees with the potential energy chart which indicates window glass as the building features that has the greatest energy saving potential. It is recommended that to modify the IAS building with all three aspects to maximize energy reduction.

LEED and BEAM Plus Compliance are checked with alternative designs. Only the case with the IAS building model having translucent wall panels (U-0.10, SHGC 0.06, Tvis 0.04) and the combined case earn LEED EA 1 credits; whereas all cases mentioned above are eligible for BEAM Plus Section 4.1 EU 1 credits.

This project used Building Information Modeling (BIM) and BIM compatible software, Computational Fluid Dynamic (CFD), to analyze the indoor environmental quality of current UG Hall VII building in HKUST under mechanical and natural ventilation. The results obtained from the software analysis were used for evaluating the indoor environment with green building standard BEAM Plus EB Ver. 2 Selective Scheme. Indoor environmental quality analysis and energy analysis on different air-conditioner usage scenarios and modified air-conditioning system were also conducted to investigate whether any modifications could give rise to indoor environment that able to reach BEAM Plus standard while reducing energy consumption. We founded that opening one air-conditioner, with temperature set as 24℃, in only one bedroom in a suite could achieve favourable indoor environment while reducing half of the energy usage on cooling. Also, changing the air-conditioning system from window-type air-conditioners to centralized system could also lower energy consumption on cooling while keeping a comfortable indoor environment. N.A.

HKUST Analysis and Evaluation of Low Carbon Building Features Using Building Information Modeling FYP 06/2018 CHAN, Yin Yee

Building sector contributes to more than 30% of the global greenhouse gas emissions, which is the major source of greenhouse gas emissions. In Hong Kong, a high-rise and high-density city, about 60% of carbon emissions and 90% of energy expenditure come from buildings. Mitigating the environmental impacts caused by the building sector can be achieved by low carbon buildings. However, previous studies on carbon emissions from buildings mainly adopted manual processes and only a few studies applied computational fluid dynamics (CFD) into the analysis and calculated the carbon emissions using the CFD results. Therefore, the comparison between buildings with different features is laborious. Building information modelling (BIM) enables comprehensive and accurate analysis of low carbon building features by collaborating with various simulation systems. By incorporating CFD into the analysis and evaluation of the carbon footprint of different Hong Kong public housing standard blocks using BIM, the research of low carbon building is extended. Revit models of three common Hong Kong public housing blocks are created, and the embodied carbon is quantified by using the material schedules and the corresponding carbon emission factors of different construction materials. The operational carbon is quantified by using the energy simulation results and the CFD results. By considering the total carbon emissions throughout the life-cycle of the buildings, it is found that the harmony block has the lowest carbon emissions among studied public housing standard blocks. When considered the effect of natural ventilation, the energy consumption of the buildings can be reduced up to 17%. N.A.
HKUST Analysis of Urban Walkability Using BIM and 3D GIS Models FYP 06/2020 LAI, Chi Ching

Walkability, which is defined as the friendliness of a city or district towards walking, has been evaluated in the current Urban Design Report released by the Planning Department. The ultimate target of urban planning is not only being walkable but also provides comfortable walkways for pedestrians to travel through the city. Surveying and walking audit are the two common methods to measure the walkability of a district. However, the two methods are subjected to personal views and labor-intensive in data collection. This study tries to integrate Building Information Modeling (BIM), medial axis transform (MAT) network, and pedestrian flow simulation to analyze the walkability of Kwun Tong District. This approach digitizes the study region with rich geometric and semantic information for comprehensive analysis, which could present high similarity to the real environment. The BIM model of this study is a 3D model of the Kwun Tong District binding with information of the walking facilities such as the opening hours and slope of the walkway. The 3D pedestrian network, which indicates the walkable paths in the 3D model with walkway information, is built on the BIM model in order to calculate the time cost using a self-defined utility function. Pathfinder is used for pedestrian flow simulation to capture videos of pedestrians walking in the specific route in the BIM model, which gives realistic and clear illustrations in the walking environment. This study covers the area along Ngau Tau Kok Station to Kwun Tong Station, including residential area and commercial area, which is able to simulate various pedestrian walking behaviors in different districts. Three phases of simulations are carried out in the study region in this project, trying to demonstrate the working principle of the study method by analyzing the walkability of a specific region, sorting out the problems, and trying to improve the walkability with alteration in the BIM model. The ultimate target of the study is to provide a platform for walkability analysis so that the effectiveness of the urban planning policies can be simulated before adoption. N.A.

Walkability problems are serious issues that influences people’s daily lifestyle. Providing a walkable environment is crucial to maintaining the living standard of people. Therefore, the proposal of Policy Address 2017 from the Hong Kong government has proposed the idea of the development of a walkable city. Kwun Tong was industrialized in an early stage and it was realized that many facilities were not satisfied with the standard of the barrier-free facility so it had undoubtedly been one of the targets. In the past, people analyzed walkability problems using the scoring system, observation or on-site investigation. However these approaches were extremely time-consuming, and were lack of efficiency and effectiveness to tackle the problem. Also, it was difficult to realize both macroscopic and microscopic problems at the same time. Hence, this project aims at dealing with the walkability problems by applying the smart technology, Building Modelling Information Technology (BIM) as well as Graphic Information System (GIS) while this report is mainly focusing on the BIM part at this first developing stage. BIM has been applied in the architecture, engineering and construction (AEC) industry for over a decade but there is less application on the walkability problems in Hong Kong.

The ultimate objective of this project is to enhance and promote the concept of walkability to citizens by applying the policy using smart technology. This project is divided into three stages. The first stage will develop a 3D BIM model of the real district, Tsui Ping North Estate in Kwun Tong. The second stage aims at drawing the 3C line network on the 3D BIM Model so that it can present the walking path of people in different situations. Some selected paths will be used to evaluate its cost and the lowest cost will be considered as the perfect path. In stage three, based on this perfect condition, information will be exported to simulate the walking behavior of people in a different situation. By applying BIM Technology, it can demonstrate the real situation in the computer so as to find out the walking difficulties of people, particularly our targeted group, wheelchair users and the elderly. Likewise, making modifications in the current design, extensions of the walkway or any other possible suggestions will be provided according to the demonstrations so that we can develop a walkable city in the future.
