FOREWORD
Building related activities account for 90 per cent of Hong Kong’s total electricity consumption, and 60 per cent of the city’s greenhouse gas emissions. Promoting Green buildings and reducing energy consumption in buildings, therefore, play a crucial role in saving energy and achieving carbon neutral.
The vision of Hong Kong Green Building Council (HKGBC) is to help save the planet and improve the well-being of the people of Hong Kong by transforming the city into a greener built environment. Since its establishment in 2009, the Council has been operating Hong Kong’s own home-grown Green building rating system, BEAM Plus. With continuous updating and upgrading, the system now covers new buildings, neighbourhood, building interior, existing buildings and special buildings such as data centres.
Whilst promoting the design and construction of new Green buildings, we must not lose sight of the large stock of existing buildings. Hong Kong has the world’s largest collection of existing skyscraper buildings, all of which have huge potential for energy savings through retro-commissioning. HKGBC’s retro-commissioning covers existing offices, shopping centres, schools and NGO premises. When promoting retro-commissioning, we should also encourage and incorporate building maintenance at the same time to enable our building structure and fabric to become more sustainable, thereby deferring demolitions.
A built environment comprises not only buildings, new and old, but also its other components. They are infrastructure, open space, public facilities, neighbouring Green areas, and natural resources.
To meet the United Nations' goals, particularly in the light of the recent COVID-19 pandemic, it is vital for us to think of all those components as a single entity—a single complex’ ecosystem, so that we can better mobilise and maximise the use of the natural attributes—namely sunlight, water, greenery and air to improve ventilation, health and well-being, thereby supporting a circular economy and Green investment.
We, therefore, welcome the Government’s initiative as stated in the 2020 Policy Address to collaborate with HKGBC to explore the development of a sustainable assessment tool for infrastructural works. In addition, we will commission a study to produce a Guidebook to guide Green and sustainable design for the built environment.
There is good potential of extending the concept to development of new areas and regeneration of old ones in Hong Kong and perhaps in the Greater Bay Area, for assessing the Green performance of buildings, infrastructures and the built environment, and supporting Green financing for these projects.
To contribute to achieving carbon neutrality by 2050 as stated in the Hong Kong’s 2020 Policy Address, HKGBC will launch Hong Kong’s first-ever “Advancing Net Zero” Ideas Competition, and an Advancing Net Zero International Conference in 2021 to encourage innovative ideas to foster the building sector towards carbon neutral.
Cheung Hau-wai, SBS Chairman of Hong Kong Green Building Council
