Water-saving strategies
Water conservation may not seem like an important issue for buildings in Hong Kong because of its low water and
sewerage tariff structure. However operating a large shopping mall can use a lot of water for landscaping, cleaning and
flushing. Throw in a few restaurants, fast food shops, laundries and hairdressers, and water use goes up dramatically.
How can mall operators and individual tenants contribute to protecting and conserving water resources?
Water conservation in shopping malls
Stanley Plaza
The annual water consumption and flushing water consumption of Stanley Plaza have been reduced by
38% and 28% respectively in comparison with the HK-BEAM baseline for buildings. To achieve these two
successes, the project implemented the following strategies:
• Low-flow water fixtures
• Infrared sensor controlled water taps
• Flood detection sensors
• Adequate checking meters for auditing purpose
• 75% of new trees planted are native species
• Dual flushing system and infra-red sensor operating urinals
