What Are Some Water Efficiency Methods For Green Building Design?

Water efficiency is one of the most important Green Building strategies. It can help you save energy, reduce environmental impacts, and protect the world’s water supply. Water is a vital resource used for many purposes, including showering, washing dishes, flushing toilets, and even watering your garden. But we all know that water resources are limited, and there is a need to minimize water waste.

In order to conserve water, you need to understand how to design a sustainable building. By understanding the different methods of water conservation, you can design an environmentally friendly building that is more efficient in all aspects.

Calculate the water usage

The first step is to calculate your building’s water use. This is done by tracking all fixtures and appliances that use water. Once you know how much water is used, you can choose the most efficient fixtures for each space.

You can also track your building’s water usage with a water monitor that shows real-time information on the amount of water used by each fixture or appliance. This is important because it helps people to make more informed decisions about their water usage habits.

This information can then be used to inform users of water-efficient options, such as low-flow faucets and showerheads. Using water-efficient fixtures can help your building save up to 20% on its overall water consumption.

Reuse soiled greywater and install filters

Other strategies for reducing water use include reusing soiled greywater and installing filtration systems to reduce bacteria in potable water. These techniques can also help your building be more energy efficient.

A common method for reusing greywater is installing greywater recycling systems that collect and treat wastewater from kitchens, sinks, and showers. This water is then reused in flush fixtures and can help you save up to 15% of your water usage.

Install rainwater harvesting systems

Another method for reducing water use in your building is to install rainwater harvesting systems. This is a simple way to store and collect rainwater that can then be used for irrigation, flushing toilets, or other uses that require water.

Use a net zero water strategy

Lastly, you can use a net zero water strategy to reduce water use. This means that your building’s annual water use should be completely offset by alternative water sources, plus treated wastewater and stormwater that has been returned to the original water source.

To sum it up

Using water-efficient fixtures, reusing greywater and stormwater, and designing for net zero water are all effective water efficiency methods. In fact, you can achieve a platinum level in the Leadership in Energy and Environmental Design (LEED) program by designing for these types of buildings. In addition to implementing these strategies, you can encourage people to reduce their water usage by making it more visible. The Prius Effect is a concept that states that when people are informed about their water usage, they will be more likely to change their habits.
