Week 4 - Materials and facilities management Flashcards
What classififies as efficient use of building materials and water?
- Integrated environmental-economic performance
- Enviornmental performance (Life Cycle Assessment (LCA)) –> determine environmental impacts of buildings in all life stages (manufacture, installation, operation, etc.)
- Economic performance - cost of supply, installation, operation
What are the LCA (Life Cycle Assessment) categories?
- Raw material
- Building material production
- Transport
- Building shell construction
- Use
- Demotion
- Transport
- Landfill or recycling plant
What is TTV?
- Total heat gain into a building through its envelope (walls, roof, windows, etc.)
- OTTV: overall thermal transfer value –> measure of the energy consumption of a building envelope in Passive Design
- RTTV: residential transfer value
- Reduces greenhouse gas emission
- Radiation + convection & conduction –> through walls
What does water and water conservation look like in Hong Kong?
- 17 resevoirs in Hong Kong around the city
- 21 treatment works around the city
- Extremely high rainfall
20 - 30% of hong kong’s water supply comes from local sources - With climate change –> less rainfall but heavier and more volatile rains are projected
- Pretty good water collection and treatment and reclamation systems and plants
- Also constructing a desalination plant
What is the strategy HK uses for water conservation and management?
—Total Water Management (TWM) strategy—
- Balance between conservation and development
- Water demand magement —————-
- Education
- Promote water saving devices
- Control leakage
- Seater for toilet flushing
- Water supply management ————
- Protect water resources
- Water reclamation
- Seawater desalination development
What are some important considerations in waste management?
- Houshold waste (local gov manages)
- Commercial waste (dischargers manage): includes:
- construction waste
- general waste
- hazardous waste
What is the summary for hong kong’s blueprint of sustainable resource use?
- VISION- change culture and faily life
- STRATEGY- plan to conserve and reduce
- REDUCE- reduce waste by 40%
- POLICY- government (laws), community participation (encourage), infrastructure (faiclities)
- Hong Kong does a much worse job of reducing waste than other comparable cities (Taipei, Tokyo, Seoul) –> they’ve implemented a lot of reduction campaigns and have used a lot of the above “POLICY” strategies
Where are the landfills in HK?
- Hong Kong relies on landfills a lot mmore than other similar places
- Northeaster New Territories (NENT
- West New Territories (WENT
- South East New Territories (SENT
What is the waste reduction management hierarchy? (5 steps)
Prevention
Reuse
Recycling
Recovery
Disposal
What are some policies and legislation Hong Kong is developing surrounding waste management?
- Quantity-based waste charging (MSW (municipal solid waste charging scheme) charging, construction waste charging)
- Producer responsibility schemes (plastic bags, electronic equipment waste, glass bottles, others)
- Ehancing recycling facilities
- Reduction of food waste (Food Wise, Food Waste Recycling)
- ECF (community project support)
- Community collaboration (industry stakeholders, district councils)
- Others (BEAM Plus, Green Procurement)
What is green procurement?
Green procurement: regularly review green specs on commonly used products and continue promotion of green prodcurement gov policies
Give me names of schemes Hong Kong has implemented to reduce waste?
- Municipal Solid Waste Charging Scheme (also has worked pretty well, landfill waste has reduced quite a bit)
- BEAMPlus
- Green procurement
- ECF
- Food Wise
- Construction Waste Disposal Charging Scheme (has worked quite well, waste has gone down a lot)
What has the government done to implement infrastructure to support these goals?
- Community Green Stations (CGS) - recycling
- Public cargo working areas (PCWA) - recycling
- Waste seperation and collection system
- WEEE treatment plant (EcoPark) - processes Waste Electrical and Electronic Equipment
- Landfill extensions
What is EcoPark?
- Aims to provide long-term land at affordable cost for recycling indsutry in HK
- A WEEE treatment facility is being developed there
How does Municipal Solid Waste charging work?
- Charging by desginated bag - people have to dispose of waste properly in diesgnated bags
- Charging by weight - oversized waste disposal is charged
