Abstract
Building material applied in a Transit-Oriented Development (TOD) area should meet high requirements such as having heavy-duty capacity, high durability, low maintenance, cost-effectiveness, and environmental-friendliness. In a tropical-rainforest or hot-humid climate, some of those requirements are intensified, especially those which are related to solar radiation and rainwater. Most existing urban development in a hot-humid climate must endure problems caused by uncontrolled stormwater and urban heat island (UHI). The idea of adopting a transit-oriented paradigm into the existing cities, convey a question whether the shift will be determining the liveability of the area; whether it could solve the existing problem or, on the contrary, generate additional problems. To overcome problems of an existing urban area and anticipate the requirements of a TOD area, the researcher progressively develops numerous materials under the term such as ‘advanced material’, ‘green material’, and ‘smart material’. This review covers current trends in material research which is relevant for TOD in a hot-humid climate. The identified trends are analyzed to generate discussion in which the TOD planning in hot-humid climate should consider and anticipate the prospect of advanced material.
Highlights
Transit-Oriented Development (TOD) refers to a high-density built environment integrated with transit systems [1]
Discussion on material research trend In the first stage of the keyword survey, we found that the all-time cumulative data of ‘green material’ and ‘smart material’ mostly talks about construction material
The emergence of recycled material, organic-based material, retrofit material, and mitigation material should not be ignored. These emerging materials could be the solution to intensified problems in the TOD
Summary
Transit-Oriented Development (TOD) refers to a high-density built environment integrated with transit systems [1]. In TOD areas with the rail-transit system, stations, and pedestrian corridors/routes are the key Other forms of 'waste' specific to TOD are noise and vibration [14], which affect certain areas close to the main transit centre (s). All those concerns are directly or indirectly related to the choice of material in the development. The identification is used to evaluate development history, provide a suggestion for present application and future planning
