Urban Renewal Authority 2018-19 Annual Report

58 CORPORATE SUSTAINABILITY Applying Green Innovative Technology At “H6 CONET”, a biofilter system was installed as a green wall to improve the indoor air quality. A distinctive drop of pollutants such as VOC, PM10 and CO 2 in the air flow has been realised since the installation. With the biofilter system, visitors in “H6 CONET” can enjoy clean and fresh indoor air. Meanwhile, an energy flooring, another pilot green initiative, was installed at the Tung Man Street entrance of “H6 CONET”. It is a versatile custom-built flooring system generating electricity via walk-through electro-magnetic induction of pedestrians. The renewable energy can be stored and used in real- time lighting displays for interactive engagement and educational purpose. We will further explore other suitable applications of the system in our forthcoming projects. The URA is also exploring the feasibility of using Modular Integrated Construction (MiC) in its redevelopment projects. Under MiC, free-standing integrated modules are manufactured in a prefabrication factory and then transported to the site for installation in a building. MiC is therefore a sustainable and environment-friendly construction method which can reduce dust and noise pollution from construction sites, minimise construction waste and improve construction waste management. Greening Our Operation We are also aware of the implications on the environment of our own operations and managed properties. We conduct an annual carbon audit of our owned/managed premises which allows us to measure our environmental performance, and instigate more conscientious behaviour among our colleagues and business partners. The Environmental Campaign Committee (ECC) awarded the Carbon Reduction Certificate to URA’s headquarters premises in 2018 for achieving 24% carbon reduction, which is valid until 2021. Furthermore, under the ECC’s schemes in 2018, the URA obtained Hong Kong Green Organisation Certification (HKGOC) for waste reduction and recycling as well as the HKGOC’s Wastewi$e Certification at the “Excellence Level”. Also in 2018/19, Indoor Air Quality Certificates for URA offices have once more been issued by the Environmental Protection Department. The URA continued to adopt e-Freezing Surveys for redevelopment projects commenced in 2018/19 by using tablet computers as an environmentally friendly measure and for enhancing efficiency in data reporting. E-valuation reports were also introduced for affected property owners’ inspection to reduce paper usage. The URA has continued to adopt BIM in its business operations to achieve the goals of sustainable construction. The “Starter Homes” Pilot Project at Ma Tau Wai Road, “eResidence”, was awarded the Hong Kong BIM Award 2018 from Autodesk for its development of automated calculation of saleable areas. Central Market Revitalisation Project has also leveraged the BIM technology in building construction. Besides, the URA engaged a consultant to develop a 6D BIM – Facility Management for Shanghai Street/Argyle Street Project, which could be expanded to cover future projects retained by the URA. The energy flooring at “H6 CONET” aims not only for energy saving but also for interactive engagement and educational purpose.
