The building facade exposes 2 visible pieces of information: - the high-density of inhabitants and its concentration on Hong Kong Island pushing the upwards expansion of buildings with more units or businesses giving this recognisable thin-looking aesthetic. The invisible information is the social level of the inhabitants, health impacts, reduced privacy and quality of life in result of living in a confined space. - the number of air conditioning units showing an old building design where the energy management is not centralised and unlikely to be controlled efficiently. The invisible information is the energy waste that comes out of old building designs if we benchmark against with modern constructions. As a result of knowing the waste induced by old constructions and air conditioning systems along with tenants habits, an energy-saving planning and awareness campaign could be laid down. The plan could give incentives to decentralised the overpopulated area (leveraging on transport infrastructure), create policies for new buildings development (max inhabitants per unit, common facilities) and greener energy management (monitored, maintained and centralised air conditioning systems).
