Good News on Conserving Water from the International Green Building Conference

Part 2 of 5

WaterSense is the new Energy Star!

It would be more accurate to say: electricity is to Energy Star as water is to WaterSense (remember those statements from SATs and ACTs?)

Most people are aware that “Energy Star” rated appliances have met strict guidelines to be energy efficient. Now be on the lookout for the “WaterSense” conservation rating for toilets, shower and bath faucets, and irrigation systems. According to Kohler's research, WaterSense faucet can reduce water use by 30%, saving a typical family 11,800 gallons of water a year.

I had the opportunity to interview representatives from Delta and Moen at the International Green Building Conference (IGBC), and they told me that within a year, ALL of their bathroom faucets will be WaterSense certified. I had the opportunity to tour Delta's headquarters in Indianapolis in 2008, and I was very impressed with the company culture. They have what I call a drop-in synergy center for facilitate getting in the creative zone for design. They have developed Diamond Seal technology so faucets are built to last, which is also very green, keeping things out of the landfill!

There has been a great challenge for determine the rating guidelines for efficient showerheads—what good would it do to lower gallons per minute if it took twice as long to rinse out shampoo? Or if the aeration cools the water so much that you end up using more hot water? If you have a bath shower combination, a good way to test your shower head is if the water running out of the tub spigot feels to be the right temperature, and when you channel the water to the shower and you have to turn up the hot water, the aeration is significantly cooling the water. Delta has solved this by developing a technology to make the water droplets larger, so they retain their temperature, and you still get a drenched feeling with the lower gallons per minute flow. Moen put a toggle switch in their rain shower, so the user can get a concentrated stream to rinse out shampoo. Their showerhead has a spoke design with stream channels so there is better coverage over the body. A WaterSense showerhead will save a typical family an equivalent of 385 bottles of water in a week! Kohler was also present in the exhibit hall, and have earned the recognition of being WaterSense Manufacturing Partner of the Year for 2008 and 2009.

Do you use a water softener? It typically uses salt, electricity, and a lot of water to backwash—typically 120-150 gallons a week to take out the minerals of calcium and magnesium to avoid scaling and deposits. Because of the significant waste of water, and that it dumps a lot of sodium into the water system, California is banning salt-based water softeners. How can one protect pipes, hardware, appliances, and surfaces from hard water damage? You can get a water conditioner that does not use electricity or salt. One type of water conditioner uses magnets to change the surface structure so they do not deposit, and can help descale buildup. I learned this interviewing a representative of Superior Water Conditioners at IGBC. A salt free water conditioner uses nanotechnology filtering to change the ion structure so the minerals will not cling to surfaces, but will not descale deposits. Know that one will not get that slick feel that salt “softened” water gives.

Product offerings are always changing. Ask your remodeling professional what products they’ve researched and recommend that are eco-friendly or "green." You can see a list of some companies we use and are very happy with their product and customer service here (at the bottom of the page).
