What is Green Building?

Many may consider a green building as a building that comes with green walls and solar panels to beautify and protect the environment. It is way more than that. Green building is a multi-disciplinary subject and has a profound impact on us.

Generally speaking, green building is a practice of reducing the environmental impact of buildings and enhancing the health and wellbeing of building occupants by:

  • Planning throughout the life-cycle of a building or a community, from masterplanning and siting to design, construction, operation, maintenance, renovation, and demolition with a focus on the impact to both the environment and people.
  • Optimising efficient use of energy, water, and other resources to avoid overconsumption and adopting the use of renewable energy and eco-friendly materials to minimise carbon footprint and emission.
  • Reducing the production of waste and preventing pollution of areas like water, air, noise and land.
  • Enhancing indoor environmental quality through natural ventilation and lighting as well as good indoor air quality by design and other means.

 

Hong Kong Context

One of the world’s most iconic cities, Hong Kong is famous for its unique subtropical built environment of high-rise, high density urban areas, juxtaposed with a large expanse of hilly and mountainous terrain. For many decades it has been one of the world’s most densely populated places, with the majority of its more than 7.3 million residents living and working in urban skyscrapers.

Today, as industrial manufacting is no longer a major economic activity in Hong Kong, the major source of electricity consumption is buildings like housing estates, officies and malls. Building-related activities account for some 90% of Hong Kong’s total electricity consumption, compared to a global average of 40%. In turn, this high level of energy consumption by buildings accounts for 60% of the city’s greenhouse gas emissions. It is obvious, therefore, that green buildings play a crucial role in achieving energy savings in Hong Kong, as well as the global target set by the Paris Agreement.

Green Building Certification

Globally, there are a number of localised green building certification systems, which are independent tools that could showcase and compare the environmental performance of buildings, such as BREEAM for United Kingdom and LEED for United States. In Hong Kong, BEAM Plus is the current assessment tool adopted in the market.

BEAM Plus is a locally developed assessment system, embracing a wide range of sustainability issues and covering the full building life cycle. The HKGBC is the certification body, with BEAM Society Limited undertaking the assessment process. 

From 1 April 2011 onwards, certification by BEAM Plus becomes one of the pre-requisites in applying for GFA concessions.  An overall cap of 10% of the total GFA of a development site is set.

Green Building Council and Worldwide Green Building Movement

A green building council of a country / territory is usually a not-for-profit, independent, member-based, industry driven organisation. By bringing the industry together, a green building council is the overarching body driving the sustainable development in the local built environment.

As a comprehensive strategy of driving market transformation, a green building council will put in place specific education and awareness programmes to build up the skills of the industry and shift the behaviours and mindsets of both the public and the professionals. It will also work in close partnership with the local government to help develop public policies and initiatives that will speed up the transformation towards a sustainable built environment.

A green building council may join the global network organised by the World Green Building Council (WorldGBC). Currently HKGBC is the Established Member of the WorldGBC (highest level of membership) since November 2012. HKGBC has also joined the WorldGBC Directorship to set the straegies to promote green building development globally.
