Water-Efficient Fixtures and Appliances

Detailed overview of innovation with sample startups and prominent university research


What it is

Water-efficient fixtures and appliances are designed to reduce water consumption in buildings without compromising performance or user experience. These fixtures and appliances incorporate innovative technologies and design features to minimize water usage in various applications, such as toilets, faucets, showers, and washing machines.

Impact on climate action

Water-Efficient Fixtures and Appliances in Energy-Efficient Buildings conserve water resources and reduce energy consumption associated with water heating and pumping. By promoting sustainable water use, these innovations lower carbon emissions, mitigate energy demand, and contribute to climate action by fostering resource efficiency and environmental sustainability in buildings.

Underlying
Technology

  • Low-Flow Technology: Low-flow fixtures and appliances use less water per flush, cycle, or minute compared to conventional models. This is achieved through various means, such as aerators, flow restrictors, and optimized spray patterns.
  • Sensor Technology: Sensor-activated faucets and toilets automatically turn on and off, reducing water waste from unnecessary water flow.
  • Dual-Flush Toilets: Dual-flush toilets offer different flush volumes for liquid and solid waste, allowing users to choose the appropriate amount of water for each flush.
  • High-Efficiency Washing Machines: High-efficiency washing machines use less water and energy per cycle compared to conventional models. They often incorporate features such as optimized wash cycles, load sensing, and improved water extraction.
  • Water Recycling and Reuse Systems: Graywater systems collect and treat wastewater from showers, sinks, and washing machines for reuse in toilet flushing or irrigation.
