City Speak X: A Green City, A Cool City

Speaker: Ng Tak-wah
Getting serious about standards for open space and greening


Hong Kong is surrounded by so much water and has so many green mountains, so does it really need more urban open space? How do we respond to the threats of global warming and air pollution? What is the meaning of “the urban heat island effect”? What is an “air ventilation assessment”? What value doesthe community place on open space? Is the demand for recreation and sport changing? Do we need a landscape vision and master plan? Is “green infrastructure” becoming more important than roads and railway lines in securing a sustainable built environment in Hong Kong?

Join experts, academics, planners, government officials and landscape architects in a discussion about how to stay cool in our city.

Designing Hong Kong is a not-for-profit organisation focused on sustainable urban planning. See: www.designinghongkong.com
