City Speak X: A Green City, A Cool City

Moderator: Ian Brownlee

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

CitySpeak X: Green City. Cool City: Ian Brownlee

  1. 1. Planning Depts. Hung Hom Study Public Open Space No Consideration of ‘No Development’ Option. Area of development sites 3.7 ha Hung Hom Open Space Deficit 15.5 ha. Why not create Hung Hom Waterfront Park? Public Open Space
  2. 2. Hung Hom Alternative : Public Open Space, Sports and Community Uses
  3. 3. Former North Point Estate Site Proposed development has minimal open space at Ground Level Alternative Proposal Space for recreation and greening : meets deficit in open space provision
  4. 4. Effects of Urbanisation on Livability <ul><li>This city is heading towards a hot, stuffy state of atmosphere. In future summers, the old and the weak living in their tiny rooms in the urban areas will have to face the increasing number of hot nights with no air-conditioning, little wind and the dampness arising from little sun and little evaporation. They also have to fear the attack of more germs than used to be since their natural enemies, viz. fresh air and sunshine, have been reduced in strength. </li></ul><ul><li>Unfortunately the underprivileged have to look forward to even more tall buildings along the shore or even right at the heart of the urban areas to block the little wind and sunshine left. </li></ul><ul><li>Buildings are meant to benefit people. But we have seen in the meteorological records presented above that buildings have collectively modified the urban climate in a way unfavourable to healthy living. It is high time for us to re-think the fundamentals about how urban living should look like. </li></ul><ul><li>Hong Kong Observatory </li></ul>
  5. 6. Open Space Deficit Correlates to A “Hot Spot” <ul><li>Of 12 areas quoted 10 have deficit of public open space </li></ul><ul><li>. </li></ul><ul><li>In most there are public sites zoned for sale/development which could be converted to open space. </li></ul><ul><li>URBAN MYTH : </li></ul><ul><li>Govt is providing open space to meet minimum standards </li></ul><ul><li>QUESTION : </li></ul><ul><li>Why not provide more open space and greening to directly address new issues through the public realm rather than focusing on private buildings? </li></ul>
