Tengah – First HDB Town with Smart Technologies Applied Town-Wide
At the HDB Awards Ceremony 2016 on 8 September 2016, Minister for National Development, Mr Lawrence Wong, unveiled the masterplan for Singapore’s 24th HDB town, Tengah. Envisioned to be Singapore first “Forest Town” with homes surrounded by lush greenery, Tengah will also be a smart and sustainable town.
2 In line with Singapore’s Smart Nation vision, HDB strives to leverage smart technologies to continually improve the planning, development and management of its towns. The opening of Tengah town presents an opportunity for HDB to leverage and expand on these smart technologies to bring about an even better quality living environment for residents. Tengah will be the first HDB town planned with smart technologies town-wide from the onset, making it HDB’s largest smart and sustainable development to date.
3 As with all new public housing developments, Tengah will be developed to create a sustainable living environment. This will be achieved through the application of design strategies and construction methods that promote the efficient use of water, energy, and other resources, as well as the provision of greenery and eco-friendly features.
4 For example, public housing in Tengah will be designed with a suite of eco-features to enable residents to lead greener lifestyles. This includes:
5 In addition to these features, Tengah will also be installed with a smart Pneumatic Waste Conveyance System (PWCS) to promote a more hygienic and efficient method of waste collection and management. The PWCS is an automated and enclosed waste collection system which uses high speed air suction to transport household waste via an underground pipe network to the Centralised Bin Centre. The automated system eliminates the need for manual waste collection, hence minimising waste scattering and pest issues.
6 Sensors installed in the PWCS will monitor the performance and operational status of the system, as well as residents’ waste disposal patterns and volume. Such information can help agencies optimise the deployment of resources for waste collection by varying the frequency of waste collection based on the volume of waste disposed. In addition, maintenance of the system can also be arranged through automated alerts.
7 Being the newest HDB town, Tengah will provide a new canvas for HDB to apply sustainable initiatives and smart technologies from the onset. Guided by its Smart HDB Town Framework, HDB will explore the smart solutions that can be implemented across four domains, ie Smart Planning, Smart Environment, Smart Estate, and Smart Living, to make Tengah more liveable, efficient, sustainable, and safe for residents.
8 Building on the framework, HDB will also develop a comprehensive Smart Urban Habitat Master Plan that will map out a strategic approach for the deployment of smart initiatives and technologies in Tengah. This would include identifying possible smart solutions that can be implemented, carrying out more research where needed, and exploring viable business models to adopt for their implementation. This will ensure that the solutions deployed are sustainable, and also provide opportunities for wider partnership with the private sector.
9 One example of a smart technology which will be applied is the use of the Urban Microclimate Multi-physics Integrated Simulation (UM-MIST) software in the planning of Tengah. This integrated software platform uses 3D city models to simulate the interaction of urban microclimatic conditions such as wind flow, temperature fluctuations, and solar irradiance with each other, as well as their combined effects on the surrounding urban landscape (i.e. buildings, water bodies, vegetation etc). Previously tested out on a smaller scale in some areas in Punggol, this smart planning software will now be employed on a town-level in Tengah for the first time.
10 Using UM-MIST, HDB’s planners, architects and engineers will be able to analyse key wind channels, and the solar heat gained by different urban features (e.g. concrete, vegetation, water bodies) within Tengah. This will help them to design open spaces, as well as optimise the building layouts and orientation to enhance the intensity of wind flow and promote natural ventilation within the town. More greenery can also be introduced in areas that receive more heat from the sun to mitigate heat gain and lower the ambient temperatures, bringing maximum thermal comfort and creating a more pleasant living environment for residents.

11 The sustainable and smart initiatives will be implemented progressively, as HDB develops the detailed plans for the housing districts in Tengah. The public can look forward to the exciting plans coming to fruition in a green, sustainable and smart Tengah.
