1 1 New World Centre Remodeling Sustainable Building Design and Next-Generation Mixed-Use Developments Mr. Jeff Tung, Senior Project Director New World Development Company Limited Project Management Department

2 Pressures in Urban City and Changing Climate 2 - Increased population and higher living density - Increased in energy consumption - Variable climate, increased hot days and maximum temperature (Source:

3 Sustainable Building Design Guidelines 3 Objectives - Achieve better air ventilation and mitigate heat island effect - Enhance environment quality of living space, particularly at pedestrian level - Provide more greenery

5 Vision of New World Centre Remodeling 5 The New World Centre is designated to be a vibrant hub with various stellar attractions, and this mixed-use development will be conceived as an urban oasis with dazzling features

6 Foundation work in progress in end 2012 New World Centre Remodeling and Sustainable Building Design Guidelines 6 Demolition work commenced in January 2011 with GBP approval, later that year SBD Guidelines were established

7 New World Centre Remodeling Objectives and Sustainability s Goals 7 - The large-scale development should fulfills SBD guidelines and improves micro-climate at outdoor environments by building design - Passive design to enhance building energy performance - Provide inhabitants with adaptive opportunities optimizing health, satisfaction and productivity (Source: PLEA 2009 Manifesto)
