CORPORATE SUSTAINABILITY
The Air Induction Units installed at the Yue Man Square Public Transport Interchange help improve the airflow with less energy consumption.
Applying Green Innovative Technology
The URA is keen to explore the applicability of green innovative technology in its projects. At the Public Transport Interchange (PTI) of Yue Man Square which commenced operation in April 2021, the URA has installed an award-winning local invention – the bladeless Air Induction Units (AIUs), which are capable of inducing up to 10 times of air movement as compared with conventional mechanical fan systems with less energy consumption.
At H6 CONET, a biofilter system has been installed as a green wall to improve the indoor air quality. A distinctive drop of pollutants such as VOC, PM10 and CO2 in the airflow has been realised since the installation. With the biofilter system, visitors in H6 CONET can enjoy clean and fresh indoor air.
In addition, the URA is adopting Modular Integrated Construction (MiC) method, which is sustainable and environment-friendly, for the construction of Ash Street Project (DL-11). Under MiC, free-standing integrated modules are manufactured in a prefabrication factory and then transported to the site for installation in a building, hence reducing dust and noise pollution from construction sites, minimising construction waste and improving construction
waste management. This first MiC project of the URA for private residential development, with foundation works commenced in October 2020, is expected to set an example for private developers to follow suit.

Developing Smart Innovations to Combat COVID-19
In view of the pandemic, the URA seeks to adopt ‘Smart Hygiene’ concepts in its redevelopment projects to create quality and healthy living. Some of the smart features being incorporated into URA’s in-house projects include UV-C VentGuard, touchless button for lift systems and sterilisation method for common areas. In particular, the UV-C VentGuard for sterilising air inside the vent pipes of a drainage system has already been installed in URA’s rehousing block at Soy Street and
the Central Market. These smart features will also be incorporated into DL-11 Project targeted for completion in 2023/24.
