School of Engineering Department of Civil and Environmental Engineering 76 Recyclable Hydrogel-based Brick for Construction on Mars: A Feasibility Study Supervisor: QIU Jishen / CIVL Co-supervisor: XUE Tianju / CIVL Student: YAU Long Kit / CIVL Course: UROP 1100, Fall UROP 2100, Spring UROP 3100, Summer After the introduction of finite element method (FEM) done last term, it is apparent that FEM is a crucial tool for approximating solutions to complex physical phenomena described by partial differential equations. This research focuses on FEM approximations to handle computationally expensive partial differential equations. The report introduces Gauss quadrature as an example. Gauss quadrature is a numerical integration method that provides an efficient way to approximate the solutions to integrals, which are fundamental components of many partial differential equations. By demonstrating the application of Gauss quadrature, the report illustrates the broader importance of approximation methods in the theoretical modelling and simulation of structural systems using the finite element method. Optimized Design of Urban Neighborhoods for Environmental Sustainability: The Effectiveness of Different Strategies Supervisor: YANG Jiachuan / CIVL Student: CHEUNG Eugene Hon / CIVL Course: UROP 1100, Spring Climate change continues to be a significant challenge that the world faces today. Under different protocols, more strategies have been introduced to mitigate global climate change. Especially with buildings in urban locations, there have been more retrofitting strategies to optimize their energy performance, such as green roofs. Although most existing studies credit the mitigation effects of green roofs, their performance is, however, evaluated without the consideration of seasonal factors. In this investigation, the goal is to examine how the seasonal changes in leaf area index (LAI) would affect the sensible heat flux of a green roof in an urban neighborhood in Hong Kong through the offline Building Energy Model coupled with Single Layer Canopy Model (BEM-SLUCM). Optimized Design of Urban Neighborhoods for Environmental Sustainability: The Effectiveness of Different Strategies Supervisor: YANG Jiachuan / CIVL Student: LO Tsun Ting / CIGBM Course: UROP 1100, Spring This research aims to assess the effectiveness of implementing void decks at ground level in buildings in Hong Kong in enhancing pedestrian-level thermal comfort, specifically in terms of temperature and relative humidity. The study utilizes the ENVI-met modeling software to create a base model that replicates the environmental conditions of a selected site in Tseung Kwan O. The model allows for modifications to be made at the ground level of the buildings. The modified results are then evaluated using the empirical Temperature-Humidity Index. The findings indicate that there is no significant difference in thermal comfort, which may be attributed to the well-designed neighborhood. However, it is recommended to conduct the experiment at additional sites to further explore potential correlations.
