Achieving Zero Carbon for buildings in a Densely Populated City and a Subtropical Climate

摘要

In Hong Kong, the buildings consume most of the energy and are the major contributor to the Green House Gas (GHG) emissions. GHG emission reduction requires rethink of the planning and design processes as well as behavioral changes. Construction Industry Council (CIC), as the construction industry coordination body in Hong Kong, has developed the ZCB, the first zero carbon building in Hong Kong. The main objective of the ZCB is to showcase the state-of-the-art eco-building design and technologies to the construction industry locally and internationally as well as to raise the awareness of low carbon living in Hong Kong. The ZCB integrates the state-of-the-art design and technologies within the context of a high density city and the subtropical climate. This paper presents the technologies, the energy strategy and the carbon strategies of the ZCB and highlights the importance of the behavioural changes as well as technologies in achieving the zero carbon emissions.
