Sustainable management

Sustainable Management

  • It is about the management of ‘ecosystems’

    • natural ecosystems

      • e.g. water, atmosphere, soils, wetlands, forests

      • provide ecosystem services e.g. support of the food chain, harvesting of animals or plants, and the provision of clean water or scenic views

    • other ecosystems

      • landscape ecosystem

      • building ecosystem

      • human ecosystem


Sustainable management1

Sustainable Management

  • Interactions between human and nature

    • land use

    • land cover

    • production

    • consumption

    • disposal

  • Sustainable construction

    • consider the influences on the ecological and social surroundings

Interactions between human and nature


Sustainable management2

Sustainable Management

  • Sustainable design principles

    • economy of resources

      • energy, water, and material

    • life cycle design

      • consider environmental quality, functional quality and future values

    • humane design

      • reduce impact on nature

      • ensure human comfort and health

Resource efficiency

Resource Efficiency

  • ‘Eco-efficiency’

    • combines the efficient use of both economic and ecological resources

    • sustainable management of natural resources

      • conservation and sustainable use of ‘biodiversity’

      • the ‘ecosystem’ provides services

        • e.g. purification of water supplies by aquatic life-forms

      • adoption of more sustainable patterns of production and consumption

The three legged stool of sustainability


Resource efficiency1

Resource Efficiency

  • Aim

    • to reduce the demand and the costs for energy, water, and materials

  • Results

    • monetary savings which benefit the local economy

    • reduced environmental impact

    • conservation of resources

  • Integrated resources planning (IRP) & management


Resource efficiency2

Resource Efficiency

  • Major factors

    • appropriate material selection

    • waste minimisation

    • recycling of building materials

    • efficient use of water

  • They also promote

    • increased durability of buildings

    • cyclical utilisation of materials

The input and output streams of resource flow


Water conservation

Water Conservation

  • Methods

    • leak detection & prevention

    • efficient fixtures/appliances (e.g. low-flow toilets)

    • correct use of appliances (e.g. washing machine)

    • water use for landscaping & irrigation

  • Green design issues

    • greywater reuse and rainwater recycling

    • composting toilets & wastewater treatment

Waste management

Waste Management

  • Sources of solid waste

    • residential & commercial

    • industrial & agricultural

    • construction

  • Elements of solid waste management

    • waste generation, on-site storage, collection

    • transfer and transport

    • processing and recovery

    • disposal (e.g. landfill, incineration, composting)


Waste management1

Waste Management

  • Green strategies

    • waste prevention

    • construction and demolition recycling

    • architectural reuse

    • design for material recovery

  • Important factors

    • on-site collection & storage space

    • sorting & separation (paper, glass, plastic, metal)


Waste management2

Waste Management

  • Recycling organic waste

    • make use of organic nutrients in garbage, human waste, and sewage

      • for growing crops/flowers in gardens

      • for feeding to farms (e.g. ‘urban farming’)

    • food gardens and city farmers


Hong kong s situation

Hong Kong’s Situation

  • One day in HK (popul. = 6.97 million) [1999]

    • fresh water consumption = 358 litre/person

    • electricity consumption = 13.9 kWh/person

    • food consumption:

      • vegetables 1,100 tonnes; fruits 1,800 tonnes

      • live pigs 6,200 heads; live cattle 170 heads

      • live poultry 190 tonnes; fresh eggs 200 tonnes

      • freshwater fish 120 tonnes; marine fish 170 tonnes

    • solid waste production = 18,040 tonnes

Hong kong s situation1

Hong Kong’s Situation

  • Waste reduction framework plan

    • http://info.gov.hk/wrc/framework.htm

  • Recent efforts for building industry

    • waste minimization (e.g. sanitary fittings)

    • construction and demolition waste

    • flushing volume for flushing cisterns

    • refuse storage and material recovery
