REVIT SIMULATION APPLICATION IN EVALUATING FENESTRATION STRATEGIES TOWARDS ENERGY CONSERVATION IN MALAYSIAN INTERMEDIATE TERRACED HOUSES

Wed, 27 Dec 2023 00:00:00 +0800

With Malaysia’s population rising and rapid urbanisation, terraced houses were built to respond to new social and economic needs. The modern terraced house appeals to the demand for high-density development. However, with just two or three façades available for openings on the front and rear façades, these houses, particularly intermediate units, frequently lack natural ventilation, resulting in slow and inefficient air exchange throughout the house. As a result, adjustments on fenestration that functions as passive design solutions are necessary to increase internal thermal comfort and energy savings. This study aims to determine the various forms of fenestration placement in Malaysian terraced buildings and examine how these different types of fenestrations in terraced houses affect energy consumption and conservation. This study employs Revit modelling software to create a set of prototypes of intermediate terrace houses with different fenestration treatments. Building simulation is used to record findings of building energy performance based on the annual and monthly energy consumption of each prototype. This study found that the terraced home façade fenestration design significantly reduces energy consumption. It is anticipated that the finding of this study will benefit architects and designers better understand designing more ecologically conscious terraced houses by addressing internal thermal comfort through passive design.

This study compared the vertical accuracy of existing satellite’s Digital Elevation Model (STRM, ASTER) and the latest satellite remote sensing height data set TanDEM-90m. ASTER and STRM have vertical accuracies of ± 20m and ± 16m, respectively. TanDEMX-90m was processed before use, and the RMSE range of 19-20m was confirmed for TANDEM X 90m. The result of the study shows that ASTER DEM performed better than the rest of the global digital elevation models. The SRTM error of 4m between the first and second locations may be due to systematic error due to slightly different versions of SRTM used for processing. The TANDEM X 90m had the same resolution but performed poorer in positional fitness. The study found that digital elevation models have different resolutions and accuracy levels. Tandem-X90m has a resolution of up to 3 meters, while Aster and SRTM have 30 meters. GPS-based field digital terrain models provide higher accuracy, while Tandem-X90m has a 10 cm accuracy. The models cover a limited area, making them suitable for high-resolution elevation data. The data collection methods used by the models, such as SAR sensors, also affect their accuracy and resolution. Based on the above comparative analysis, it can be recommended that the GPS-based field digital terrain model is suitable for high-accuracy and high-resolution elevation data in a limited area. Tandem-X90m is suitable for high-resolution elevation data in a limited area but is expensive. Aster and SRTM are suitable for global-scale studies but have lower accuracy and resolution.

ANALYZING THE THEORIES OF CONTRIBUTING FACTORS TO PUBLIC ACCIDENTS IN THE MALAYSIAN CONSTRUCTION INDUSTRY: A BRIEF OVERVIEW OF CONSTRUCTION WORKERS

In Malaysia, the construction industry faces a wide range of challenges, one of which is the public accident and injuries at the construction sites. Construction is well known as a labor-intensive industry, thus the need to provide awareness to construction workers regarding public accidents should be the main consideration during the project implementation. On the other hand, the unsafe acts of construction workers were also considered major contributors to public accidents and injuries at construction sites. Therefore, this study aims to analyze the factors that are related to the construction workers which contribute to public accidents in the Malaysian Construction Industry. The researcher has devised two (2) objectives to accomplish the study's purpose; (1) to explore public accident cases in the construction industry, and (2) to identify the factors related to construction workers that contribute to public accidents in the Malaysian construction industry. A snowballing technique was applied through the reference list of reviewing previous papers and the findings reveal thirty-one (31) factors that are related to the construction workers which lead to public accidents and injury. The contribution of this study can therefore be a mechanism for construction workers to manage safe conditions at the workplace and raise awareness in comprehending factors that emerge in the construction industry.

A SYSTEMATIC REVIEW OF THE NEOLIBERAL HOUSING POLICY: AN INTERNATIONAL PERSPECTIVE

In recent years, there has been a burgeoning discourse surrounding the influence of neoliberalism on housing policy, governance, and affordability. The evolution of housing policies has coincided with the global ascent of neoliberal principles. The ideological underpinnings of neoliberalism, characterized by a focus on private property rights, unrestricted flow of capital, reliance on self-regulation in free markets, and the process of deregulation, exert a substantial impact on the trajectories of housing policies and urban governance in numerous countries. This article conducts a comprehensive review of the existing literature on housing policy and neoliberalism, adhering to the PRISMA guidelines and systematic review statements, utilizing 'housing policy and neoliberalism' as keywords. The objective of this study is to identify prevalent research themes within the realm of affordable housing and neoliberalism. The primary themes influencing affordable housing policy, as indicated by the results, encompass privatization, deregulation, and privatization once more. Subthemes within this context include the privatization of public housing, the elimination of zoning restrictions or the adoption of inclusionary zoning, and the adoption of a market-driven approach. The outcomes of this study aim to streamline existing research, offering valuable insights for future research endeavors and aiding relevant stakeholders in formulating effective affordable housing policies and enhancing the governance of housing delivery mechanisms.
