Water Neutral Buildings: Achieving Zero Water Footprint through Innovative Design and Technology
Water neutral buildings use innovative design and technology to achieve a zero water footprint, reducing the demand for freshwater resources and providing environmental, social, and economic benefits. Read about the successful example of the Green Solution House in Denmark.
Buildings are among the most significant water consumers, with up to 40% of global water usage attributed to buildings. As the world faces growing water scarcity challenges, it is essential to find innovative ways to reduce the water footprint of buildings. One approach is water-neutral buildings, which use innovative design and technology to achieve a zero water footprint. In this article, we will explore the concept of water-neutral buildings, their benefits, and a case study example from Denmark.
What are Water Neutral Buildings?
Water-neutral buildings achieve a zero water footprint, meaning they do not consume more water than they produce or replenish. Water-neutral buildings achieve this through innovative design and technology, such as rainwater harvesting, water-efficient fixtures and appliances, and water treatment and reuse systems.
Benefits of Water-Neutral Buildings
One of the main benefits of water-neutral buildings is that they can reduce the demand for freshwater resources, preserving them for other uses. Additionally, water-neutral buildings can help reduce urbanisation’s impact on water resources by reducing the amount of water consumed and the amount of wastewater generated. This can lead to environmental and social benefits, such as improved water quality, reduced water pollution, and increased resilience to water scarcity.
Water-neutral buildings can also provide cost savings, as they can reduce the cost of water supply and wastewater treatment. Additionally, water-neutral buildings can provide health and wellness benefits, as they often include features such as green roofs and living walls that improve air quality and create a more pleasant and liveable environment.
Case Study Example: The Green Solution House in Denmark
One example of a water-neutral building is the Green Solution House in Denmark. The Green Solution House is a hotel and conference centre designed to be water-neutral, carbon-neutral, and energy positive. The building achieved its water-neutral status through various innovative design and technology solutions, including rainwater harvesting, water-efficient fixtures and appliances, and a treatment and reuse system.
The rainwater harvesting system collects rainwater from the roof, which is then stored and treated for reuse in toilets and urinals. The water-efficient fixtures and appliances, including low-flow showers, faucets, and dual-flush toilets, further reduce the water consumed. In addition, the treatment and reuse system treats wastewater from the building and recycles it for non-potable uses, such as irrigation and toilet flushing.
Results and Conclusion
The Green Solution House has been successful in achieving its water-neutral status, as well as its carbon-neutral and energy-positive status. In addition, the building has reduced water consumption by 75% compared to a conventional hotel, saving 120,000 litres of freshwater annually through rainwater harvesting and reuse.
In conclusion, water-neutral buildings are a promising approach to achieving a zero water footprint. By using innovative design and technology solutions, such as rainwater harvesting and water treatment and reuse systems, water-neutral buildings can reduce the demand for freshwater resources, reduce the impact of urbanisation on water resources, and provide environmental, social, and economic benefits. The Green Solution House in Denmark is a successful example of a water-neutral building in action, demonstrating the potential of this approach to create more sustainable and resilient buildings.
The Take-Out
Water neutral buildings offer a promising solution to reduce the water footprint of buildings.
