Tony Ip Green Architects - Heat Sink

Heat Sink Banner

The higher we live from the ground level, the more disconnected we feel from the natural environment and the community. Compared with people residing away from the metropolitan area, urban dwellers lack personal and open space, and may seek room to escape from the hustle and bustle of city living.

In pursuit of environmental sustainability, this installation - Heat Sink intends to examine human-nature interfaces and the paradigm shift amongst design for humans, design for humans with nature and design for nature in the urban context. Meanwhile, it presents how advanced bio-engineering, nanotechnology and renewable technology mitigate green-house gas emission, alleviate urban heat island and improve outdoor environmental quality.
