Designing Thermal Comfort in Singapore
The Landscape Architecture Studio of Prof. Christophe Girot designed and invented new landscape topologies in and around Singapore’s Railway Corridor. The goal of the studio was to improve local climate conditions and to reduce Urban Heat Island effects through ecological design. Emphasis was placed on landscape topology and regeneration aiming at improving thermal comfort and opening up a range of possibilities for future uses and developments on the city island.
The Railway Corridor, left empty since the termination of the KTM service in 2011, remains as a unique infrastructural topography in the urban landscape of Singapore. When re-opened to the public, it will be one of the longest continuous pedestrian lines connecting various new towns and natural areas of the island. Although a master-planning commission was awarded by competition in 2015, the Urban Redevelopment Authority has since rescinded the contract, and the future of this greenspace remains unclear.
This urban landscape design studio explored the use of new technologies in the exploration of possible futures for the Railway Corridor. The goal was to improve climatic conditions in neighbourhoods adjacent to the Corridor, by studying the interface of a linear park with existing urban fabric. With workshops throughout the semester, students acquired skills in point cloud and 3D modelling, visualisation techniques and CNC prototyping. The studio was conducted jointly with the Design Research Studio of Prof. Joshua Comaroff and Philipp Urech at the SUTD in Singapore and in collaboration with the Future Cities Laboratory in Singapore.
Methodological approach to the design tasks
The design evolved from the basis of a geolocated dataset, which has been provided from a number of sources (figure 1). One part was collected at various scales on the study site using Terrestrial Laser Scanning to produce an extensive point-cloud model that represents the existing environment to a high degree of precision. The data was combined with Aerial Laser Scanned data to provide dense and continous information on the site. The point-cloud formed the basis on which the students developed design proposals for urban landscapes (figure 2).
The studio explored the dataset and the actual site, which has been divided into 3 study areas. Sub-set portions of these areas were explored by pairs of students, to examine the existing conditions—and in particular, the interfacing of the Green Corridor with surrounding neighborhoods. Because of their particle structure, pointclouds are well adapted to segmentation in the form of sections, classifications or cut-out objects. This property allows to place sections in real time throughout the model and examine them separately, exposing the inner structure of the landscape where ground, plants, buildings can be recognized as distinct features (figure 3).
Students used a workflow in which specific portions of the data was exported to Rhino for modeling and CNC output, as well as Cinema 4D for point-cloud modeling and back to Cloud Compare for assemblage and visualization. In succeeding steps, the landscape is shaped with topological information retrieved from point-cloud datasets. The initial condition of the site is manipulated by locally extracting, filtering and meshing the point-cloud model where the design transformation takes place. This allows to decompose the point cloud model in entities that will edited in the design process (figure 4). From there, designers add or remove elements relevant to their project, shape topography and vegetation to compose new urban spaces. The workflow bridges spatial information of the point cloud model with meshed geometries for editing (figure 5). At the end, the tailored designs are assembled with the unchanged 3D context (figure 6).
