Low-flow plumbing fixtures: These fixtures use less water than traditional fixtures, without sacrificing performance. For example, a low-flow toilet can use as little as 1.28 gallons per flush, compared to 1.6 gallons per flush for a standard toilet.
Water-saving appliances: Water-saving appliances, such as dishwashers and washing machines, use less water than traditional appliances. For example, a water-saving dishwasher can use as little as 3 gallons per load, compared to 5 gallons per load for a standard dishwasher.
Rainwater harvesting: Rainwater harvesting is the collection and storage of rainwater for later use. This can be used for irrigation, toilet flushing, and other non-potable water needs.
Greywater recycling: Greywater is the water from sinks, showers, and bathtubs that has not come into contact with human waste. Greywater can be recycled for irrigation or other non-potable water needs.
Water-efficient buildings functionality:
Lower water bills: Water-efficient buildings can save money on water bills by using less water. This is especially important in areas where water is scarce or expensive.
Reduced demand for freshwater resources: Water-efficient buildings can help to reduce the demand for freshwater resources by using less water. This is important for protecting our lakes, rivers, and aquifers.
Protection of the environment: Water-efficient buildings can help to protect the environment by reducing pollution and greenhouse gas emissions. This is because less water needs to be treated and transported, which reduces the amount of energy used.
The future of water-efficient buildings in North America is bright. With increasing water scarcity and climate change, there is a growing demand for buildings that use water wisely.
