By using less drinking water, a building will also reduce the amount of energy needed to transport, treat and redistribute that water, not to mention the cost savings associated with reducing drinking water consumption. The excessive use of water extracted from both surface and underground sources has caused a deficit of this precious resource. Low-flow devices, sensors and the use of non-potable water (for irrigation applications) in commercial buildings and homes can greatly reduce water waste, resulting in lower volumes of wastewater, lower volumes of wastewater, lower energy use and financial benefits. Plastic pipes In addition to previous device specifications and practices, the use of certain materials for plumbing systems can also have a significant impact on water use.
For example, high-density polyethylene (HDPE) tubing is manufactured by extrusion, which produces a very smooth inner surface that, in turn, provides exceptional hydraulic characteristics. The surface of the HDPE pipe prevents the biological or chemical component being transported from adhering to the surface of the pipe. As an added benefit, HDPE pipes maintain these flow characteristics throughout their lifespan. Other types of materials can damage the inner surface of pipes; while these products begin to work with interior walls almost as smooth as polyethylene, corrosion or the formation of encrustations can cause a degradation of their flow capacity and increase water pumping costs over the life of the system.
On the other hand, the ability of plastic pipes to move water efficiently in drinkable applications remains virtually unchanged. Therefore, energy costs for pumping can remain constant over the life of the system. In addition, the life cycle cost of HDPE pipes differs from that of other pipe materials, since their fused joints mean virtually zero allowable water loss, rather than the typical leakage rates of 10 to 20 percent for other types of pipes. The combination of the flexibility of HDPE pipes and the possibility of leak-free joints allow for unique and cost-effective installation methods that rigid systems that rely on other types of connections cannot obtain.
In residential applications, cross-linked polyethylene (PEX) piping is effective in employing a manifold system for interior pipes. 1 With a PEX pipe, this system allows multiple supply lines throughout the house, meaning that hot water can reach a sink or shower more quickly. The result is greater potential for efficiency and significant savings in water use. The corrosion resistance and durability of plastic water pipes can help make them an excellent alternative to other systems that rely on traditional materials.
A two-year study conducted by the National Research Council of Canada (NRC) revealed that for every 100 km (62 miles) of running water distribution pipes, PVC had only 0.7 breaks per year, compared to 35.9 and 9.5 for cast iron and ductile iron, respectively. 3 Green buildings play a crucial role in saving 2% of the world's freshwater resources. Thanks to their technologically advanced and water-efficient architecture and design, they have become the go-to option for anyone who wants to help the global movement to save consumable water for a better future. Although 70% of the world consists of water, only 3% is freshwater.
That leaves the population with 0.4% of usable and drinkable water. Once you understand the use of water in your facilities, you can set sustainability goals. If you're working on a new design project, set these goals in the early stages of development. That way, you can start designing the structure to meet these objectives.
For example, if you and your stakeholders determine that the building should reduce water use by 20%, you can choose WaterSense accessories that facilitate these savings. Incorporating a self-sufficient irrigation system can also help achieve this goal. Before 1992, plumbing fixtures were three times less efficient than they are today. Your commercial building will use 20% less total water consumption by installing water-saving appliances and accessories.
While traditional facilities offer their residents a place to stay, green buildings aim to help their tenants live healthier, more environmentally conscious lives and to save fresh water. The Water Petals of Water section of the Living Building Challenge suggests that drinking water should not be used when it is not needed, that is, in addition, in the case of drinking water, the use of drinking water should be avoided in a green building. Green buildings are the residential answer to helping more areas of the world to help conserve water, reuse non-drinkable water and be aware of water waste. Fortunately, modern EPA standard 1.28 gallon (5.8 liter) models reduce this waste, making green building toilets save more water and be more sustainable.
Outdoors, more indirect green building strategies, such as intelligent landscaping (or xerogardening, that is, the use of plants that do not require additional irrigation, other than the expected annual rainfall in each location) can have a major impact on water use on construction sites. In addition, it has made life in green buildings more affordable by saving water and reducing energy bills. As mentioned, understanding the relationship between site location and climate has an important role to play in any green building plan. The Green Building Council (USGBC) also supports the use of non-potable water in sustainable green building projects.
Residents of green buildings do not have to worry about a shortage of water from the municipal water supply, thanks to the use of non-potable water. For bathrooms, green building technologies include ultra-low-flow toilets and urinals, which use pressure-assisted discharges, and dual-flush toilets, which distinguish between liquid and solid flush options. Because green building plants and lawns are powered by xerogardening, the practice reduces maintenance costs and water utility bills and saves the community its income and fresh water. It's beneficial for residents of green buildings to keep their environment green, clean and beautiful, not to mention that it's full of fresh air.
As a responsible resident of a green building, keep an eye out for potential leaks, electronic problems with the water heater, and problems with the water supply. Here are some of the most basic ways in which every tenant of a green building can help conserve water through their responsible use of water. These are some of the many ways in which green buildings encourage sustainable living and use fresh water only when and where needed. Therefore, the pattern of unsustainable water use in the built environment is up to par, in terms of green construction, with energy efficiency and waste management.
