Promoting Green Building Designs

While acknowledging that redevelopment and construction works would inevitably pose impacts on the environment, the URA has put continuous effort in its planning objectives to create low-carbon neighbourhoods and green buildings for a sustainable development of the environment. In 2020/21, the URA continued to embrace green building designs in its redevelopment projects, thereby improving the energy efficiency of buildings, reducing water consumption and waste generation as well as providing more green areas for the local community. With the combined efforts of both the URA and its joint-venture partners, certificates have been attained for the high standards and sustainability performance of different projects (For details, please click Accredited Projects).

Green Buildings

The URA not only dedicates its effort to promote new green buildings, but also strives to improve the green elements of existing buildings through rehabilitation. The URA introduced the Green Item Subsidy (which won a Hong Kong Green Building Council Award in 2016) under the ‘Common Area Repair Works Subsidy’ to encourage property owners to use environmentally-friendly building materials and install energy-saving facilities when carrying out building maintenance and repair works. As of 30 June 2021, the URA had approved Green Item Subsidy applications from owners of about 340 building blocks (involving approximately 16,400 units) amounting to a total subsidy of around $20 million.  

















Incorporating ‘Smart Building’ Concepts

The URA is keen to incorporate ‘Smart Building’ concepts into its development projects covering five aspects, namely Design, Information, Environment, Convenience and Management. Smart buildings will create smart and vibrant living conducive to the development of a ‘Smart City’ in Hong Kong. Smart features such as home energy and water consumption systems, home health and wellness systems, smart displays, home waste management systems, Building Information Modelling (BIM) and building management systems have been adopted in various URA projects.

Creating Liveable Environment with ‘Digital Twin’ Technology

To support our district-based and people-centric urban renewal approach, the URA pressed on with the development of the Urban Renewal Information System (URIS), a Geographic Information System-based platform which allows central data storage and data exchange across internal divisions while also serving as a portal for the collection of external data. Specifically, it enables the creation of digital twins of the built environment to support the analysis of geographical and environmental data and provide simulation of micro-climates. With a better understanding of the built environment and the potential impact of our urban renewal initiatives, the URA could make swift and precise planning decisions to ensure the creation of a more liveable environment for the community.

The URA will continue to enhance the functions of URIS. It is anticipated that the development of URIS may augment the development of the common spatial data infrastructure by the Government and enhance data sharing with Government departments. The appointed consultant commenced the system development in the third quarter of 2019, and ten ‘4Rs’ taskspecific applications have been developed and rolled out successfully by March 2021. The system development work will be completed in 2021/22.

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 Ash Street Project (DL-11) targeted for completion in 2023/24.

Originated from the Innovative Design Competition 2020 jointly organised by the URA and the Institute of Vocational Education, the ‘U-trap Refill Automator’, a winning application which detects water level and refills water in U-traps to prevent the drying out of floor drains hence reducing the risk of virus spread, was taken forward for further development.  The design of the product has been finalised and production is in progress. A total of 2,000 units will be installed in URA’s rehousing blocks and some of the acquired properties.

Greening Our Business Operation

In recognition of our efforts to maintain green operation, the Environmental Campaign Committee (ECC) awarded the Carbon Reduction Certificate, which is valid until 2024, to the URA’s headquarters premises in 2021. Furthermore, under the ECC’s schemes in 2020, the URA has obtained the Hong Kong Green Organisation (HKGO) Certification for waste reduction and recycling as well as the HKGO’s WasteWi$e Certification at ‘Excellence Level’.

In 2020/21, the URA continued to adopt e-freezing survey for the new project commencement using tablet computers as an environmentally friendly measure and for enhancing efficiency in data reporting. The URA has also developed and launched an electronic Document Management System to streamline the workflow and reduce the filing of documents’ hard copies to save paper usage. Additionally, digitalisation initiatives at multiple fronts of the URA’s operation processes such as site work supervision, building monitoring and subsidy administration are being planned to enhance the organisation’s effective use of resources.
