Theme B: Creating a livable, healthy and environmentally viable citiesannual energy saving of approximate 25TJ for air-conditioning, 0.00011gha/capitaof land could be conserved. These measures not only reduce the demand on fossilfuel but also reduce the generation of greenhouse gases.6. CONCLUSIONIndicators for different aspects of the sustainability framework including Economic,Environmental and Social was established for the unique context of Hong Kongand demonstrated using the case study of the Redevelopment of Yau Tong EstatePhase 4 of Hong Kong Housing Department.The sustainability design approach for the case study was illustrated. Performanceindicators for enhancing health and comfort environment as well as energy andwater conservation were identified. This project symbolizes the commitment of theHong Kong Housing Department to the environment and the society through anintegrated approach to green building design, from architecture to building systems.Ecological footprint, which accounts the impacts of consumption by adevelopment within the context of ecological limits, has also been incorporatedinto the design philosophy of Yau Tong Estate Phase 4. With the utilization ofnatural ventilation and water-cooled air-conditioning system, energy consumptionby air-conditioning has been minimized. As a result, the generation of greenhousegases is reduced with reduced demand on fossil fuel.7.
