Water Rating Index Added to 2018 National Green Building Standard Draft

The Consensus Committee developing the next version of the National Green Building Standard (NGBS) approved the Water Rating Index (WRI), as recommended by the Water Task Group. The WRI will go out for public comment as part of the draft NGBS. If approved, the National Green Building Standard will include the WRI methodology as an appendix and will use the WRI as one option for meeting the water efficiency requirements of the NGBS.

“The zero to 100 rating system, patterned after the Energy Rating Index (ERI) already in code, is a simple metric that consumers and water planners can understand and something builders will use to differentiate themselves from competition. It will drive greater efficiency in water conservation just as the ERI has for energy conservation”, said Kim Shanahan, Executive Officer of the Santa Fe Area Home Builders Association.

“In many areas, water is becoming the new energy,” said Craig Conner, founder of Building Quality. “The WRI is a single number representing the water efficiency of a home, including both the inside and outside water use. I expect the WRI to be used where water availability is limiting construction. The WRI can also be used to compare the costs of achieving water efficiency in homes with the cost of expanding the water supply infrastructure. In many cases, new-home water efficiency will be much less expensive than expanding the water supply and treatment infrastructure.”

The WRI proposal passed overwhelmingly, receiving a 90% majority approval from the Committee. It calls for the creation of an alternative compliance path, whereby builders receive credit for four levels of achievement in the water efficiency chapter depending on the outcome of their water rating. On a scale of 0-100, where lower is better, the following table was approved:

WRI NGBS Level
70 Bronze
60 Silver
50 Gold
40 Emerald

“This is great news for both water-efficient builders and water-conscious communities,” said Mike Collignon, Executive Director of the Green Builder® Coalition and Chair of the WERS Development Group. “Builders who utilize the NGBS would be able to get the credit they deserve for their water-efficient practices, and municipalities that need to ensure their water future would have an ANSI standard to employ.”

Two Charrettes Highlight Next Generation Water Summit

A limited number of attendees will be able to register for one of two charrettes at the upcoming Next Generation Water Summit. The charrettes are a new feature at this year’s Summit, with only 80 total slots available. The professionally moderated, half-day charrettes will take place on Tuesday, May 1. White papers will be produced and distributed to all Summit attendees, not just those who participate in the charrettes.

The first charrette will try to solve a hypothetical challenge: How to implement a mandated 50% reduction in urban water usage without crippling the building industry. Aimed at the building community, this discussion will utilize a diverse set of perspectives in order to entertain a complete examination of this challenge. A few of the attendees scheduled to participate include: Darrel McMaster, Founder, Sustainable Homes, Inc. (Texas); Mike Collignon, Executive Director, Green Builder® Coalition; Darrell Lehman, President & CEO, Triconic, LLC; and Kim Shanahan, Executive Director, Santa Fe Area Home Builders Association.

“The purpose of this charrette is to contemplate the integration of significant water conservation into the design/build process,” said Collignon. “I’m looking forward to the suggestions on managing customer expectations in different geographies.”

The second charrette will compile best water reuse practices and mistakes in the southwest. As many in the water industry know, alternate water sources (i.e. rainwater, greywater, blackwater and stormwater) are often managed by different entities, and practices can vary from state to state. This charrette will bring together state experts from Arizona, California, Colorado, New Mexico, Nevada, Texas and Utah to share ideas and find common paths to success. A few of the attendees scheduled to participate include: Dr. Robert Mace, Chief Water Policy Officer, Meadows Center for Water and the Environment at Texas State University; Doug Pushard, Founder, HarvestH2o; Peter Mayer, Principal and Founder, WaterDM; and Carol M. Ward-Morris, Assistant Director, Arizona Municipal Water Users Association.

Mayer asked, “Can urban water use be optimized in the American southwest? With a panel of experts representing the entire region, this charrette will consider the range of feasible water efficiency, reuse, and cooperative opportunities.”

Prospective attendees will not want to delay registering for this unique opportunity, as seats are limited. Early bird registration expires on March 7, so people are encouraged to sign up now. For more information on the rest of the Summit, please visit www.NextGenerationWaterSummit.com.

Hosts of the Next Generation Water Summit will be the Santa Fe Green Chamber of Commerce, Green Builder® Coalition, City of Santa Fe, the Alliance for Water Efficiency and the Santa Fe Area Home Builders Association. Santa Fe Community College is the official education sponsor, and Green Builder® Media is the national media partner.

The Next Generation Water Summit brings together the building and development community, water reuse professionals and water policymakers in a collaborative setting to share best practices and learn about innovative water conservation and water reuse techniques that can be used to comply with water conservation restrictions spreading across the southwest.

Green Builder® Coalition Selects Triconic to Expand WERS Program

The Florida Home Builders Association (FHBA) recently announced their sponsorship of a new Certified Ratings Program; offering single-family homebuilders access to independent energy and water ratings based on Florida’s Energy Code and Water Star℠ owned by the St. Johns River Water Management District. For the Program, Triconic created a partnership between Water Star℠, the FHBA, UL and Intertek. The partnership gives home builders a program to get energy and water ratings from the same professionals.

The Green Builder® Coalition has also selected Triconic to administer the Water Efficiency Rating Score (WERS)® and therefore is taking steps to further its support of Water Star℠ objectives and offer certified WERS ratings. WERS provides a performance-based water efficiency rating and complements the prescriptive-based Water Star℠ Program.

“Builders love the flexibility, and with WERS, they’ll have the choice of a prescriptive water rating through Florida Water Star℠, or a performance-based water rating with WERS,” said Green Builder® Coalition and WERS Development Group Chair Mike Collignon.

“The Certified Ratings Program is the first to establish itself among state home builder associations, but with the support and scale of UL and Intertek, it is anticipated that other states will push expansion of similar programs beyond Florida starting late in 2017 and into 2018”, says Darrell Lehman, President of Triconic. Lehman continues, “There is such tremendous support for comprehensive energy and water rating options. So Triconic will continue fostering partnerships to bring builders more options like bringing WERS to Florida.”

Kim Shanahan, Coalition Board Chair, agreed. “The partnership Triconic assembled sets an exciting precedent that can and should be replicated with HBAs across the nation that seek to provide performance-based choices for rating energy and water usage in homes built by their members. The Green Builder® Coalition is eager to assist Triconic as it expands its outreach to other state HBAs.”

“This is a partnership we’ve been working on for quite some time,” said Collignon. “We always knew we would need assistance meeting demand from across the country. With the partners involved, we can take a program that originated in Santa Fe, NM and elevate it to the national (and potentially international) stage. The Coalition’s Board of Directors and the WERS Development Group are excited for the expansion of WERS.”

Next Generation Water Summit To Be Held In Santa Fe

Santa Fe will host the inaugural Next Generation Water Summit on June 4-6, 2017. This first-of-its-kind, national event will feature three educational tracks, two keynote speakers and an expo. The Summit will begin with the Green Expo, an exhibition presented by the Santa Fe Green Chamber of Commerce. All events will take place at the Santa Fe Community Convention Center.

Water scarcity is emerging as a critical challenge to the western United States. The limits of water could halt construction in the west, bringing economic development to a standstill. This Summit will bring together a broad range of stakeholders to develop strategies that integrate a variety of interests and develop real solutions. “Making our communities sustainable in the long term given predicted drops in renewable surface water flows, and resilient to short term and long term impacts from the effects of climate change, are critical issues across the Southwestern United States, as well as many other regions around the world,” said City Councilor Peter Ives. “The City of Santa Fe is honored to host the Next Generation Water Summit, which is designed to continue the dialogue on how we can and must do more with less water.”

Three tracks will focus on emerging policy development, building design and construction, and water conservation tools and technologies, respectively. “The unique aspect of this event is the integration of field professionals into policy development and design,” said Green Builder® Coalition Executive Director Mike Collignon. “The Next Generation Water Summit aims to close the loop on water efficiency, so that those who create and manage water efficiency programs can network with the practitioners of those programs.”

Pre-Summit courses will include a Water Efficiency Rating Score (WERS®) Verifier course, an ARCSA Rainwater Harvesting AP course, a 2-day Greywater course and a Qualified Water Efficient Landscaper (QWEL) course. All will be held at nearby Santa Fe Community College. The Summit will be the first event to offer continuing education for those trained in either the WERS Program or WaterSense for Homes.

This event is being co-hosted by The City of Santa Fe, the Green Chamber of Commerce, the Green Builder® Coalition and the Santa Fe Area Home Builders Association. Sponsorships, booths and attendee registration will be available in the coming weeks. For more information, please contact:
