    Second Public Comment Period for Water Rating Index:

    BSR/RESNET/ICC Standard 1101

    Standard for Calculation and Labeling of the Water Use Performance of One- and Two-Family Dwellings Using the Water Rating Index (BSR/RESNET/ICC Standard 1101)

    Comment period March 15, 2019 - April 29, 2019


    Water is the new frontier for RESNET and HERS Raters.

    In many parts of the nation, water is fast becoming an ever increasingly expensive commodity. There is clearly a need for a system to rate a home's efficiency in water use. This will allow home buyers to know how efficiently water is being used in the homes they are considering buying. It will also provide an opportunity for homebuilders to monetize the efficiency of their homes in the same fashion that the HERS Index plays for energy efficiency.

    Proposed Standard BSR/RESNET/ICC 1101-201x, Water Rating Index, establishes a uniform methodology for evaluating, rating and labeling the water use performance of single family and duplex dwelling units.

    The Standard provides a consistent, uniform methodology for evaluating, quantifying, and labeling the water use performance of one- and two-family dwellings. The methodology compares the water use performance of an actual home (rated home) with the water use performance of a reference home of the same geometry, resulting in a relative Water Use Rating called the Water Rating Index (WRI). Where the water use performance of the actual home and the reference home are equal, the Water Rating Index is 100.

    The first draft of proposed standard BSR/RESNET/ICC 1101-201x was submitted for public comment in August of 2018. Changes resulting from comments received on that draft have been incorporated into the second draft, PDS-02, which is open for comment. All sections of the second draft of the standard (PDS-02, of BSR/RESNET/ICC 1101-201x) are open for public comment during a 45 day comment period. To review and comment on the Draft, follow the link below:

    Draft PDS-02, of BSR/RESNET/ICC 1101-201x

    Comments will be accepted on all text in draft PDS-02.

    The public comment period will be open for 45 days beginning March 15, 2019, through April 29, 2019.

    DENVER, CO – The Colorado Water Conservation Board announced the availability of new guidance to Colorado water suppliers on implementing water conservation measures through land use planning. This guidance, approved by the CWCB on January 28, 2019, is intended to provide a suite of best practices for incorporating land use planning techniques into water resources operations that can be considered by municipal water utilities and water districts and adapted to their unique circumstances.


    “This new guidance provides step-by-step instruction for water providers for collaboration with their land use authorities to configure new development in a way that reduces overall water demand,” said Rebecca Mitchell, Director of the CWCB. “Working together, Colorado water suppliers and planning departments can use a ‘smart-from-the-start’ approach that provides enhanced ability to absorb new growth, meet community priorities, and contribute to better resiliency of existing supplies without sacrificing quality or desirability.”


    State legislation in Colorado requires an evaluation of best practices for implementing water conservation and efficiency through land use measures. In addition, Colorado’s Water Plan sets a measurable objective of having 75 percent of  Coloradans living in communities that have incorporated water-saving actions into land use planning by 2025. The new guidance is intended to further both goals.


    The guidance document is a joint project of the Getches-Wilkinson Center for Natural Resources, Energy and the Environment at the University Of Colorado Law School and the Babbitt Center for Land and Water Policy, a center of the Lincoln Institute of Land Policy, with involvement and support from the CWCB. The best practices were compiled through an extensive outreach effort that included interviews of Colorado water providers, an advisory committee of experts in the field, and a day-long workshop with interested and knowledgeable individuals.


    “Many Colorado water providers have already improved their efficiency through use of inclining block rate structures, structured tap fees, and landscape guidelines,” said Anne Castle, of the Getches-Wilkinson Center and a co-author of the new guidance. “But with continued pressure on water supplies, the greatest potential for additional future water savings lies with the initial land use approval, and that process should integrate both land planning and water resources tools and concerns.”


    “Many resources for integrating land use and water planning are geared toward land use planners. In addition to meeting statutory requirements and goals of the Colorado Water Plan, this new guidance clarifies for water providers how land use techniques can reinforce their water efficiency activities,” said Erin Rugland, Babbitt Center Junior Research Fellow and co-author of the new guidance.


    Work on the best practices guidance document was made possible through funding from the Lincoln Institute of Land Policy and the CWCB. The co-authors of the study are Erin Rugland of the Babbitt Center and Anne Castle of the Getches-Wilkinson Center. The new guidance is available on the CWCB website. []


    The mission of the CWCB is to conserve, develop, protect and manage Colorado’s water for present and future generations. The Babbitt Center seeks to advance water sustainability through improved integration of land use and water planning, management, and decision making. The Getches-Wilkinson Center incorporates creative, interdisciplinary research and innovative problem solving to further sustainability for lands, waters, and environment.  For more information on the integration of land and water planning, see Colorado’s Water Plan implementation discussion [].

    The Colorado Water Conservation Board (CWCB) is providing a comprehensive program of training and technical assistance for urban water systems across Colorado. This program, known as the Colorado Water Loss Initiative (CWLI), supports a strategic objective from the Colorado Water Plan: to support water management activities for all water providers. The CWLI is structured and funded for the largest 165 water systems, though smaller systems may be considered if space is available. The focus of the program will be the AWWA M36 water audit, the free AWWA Water Audit Software, and the WRF 4639 Level 1 Validation methodology.

    The program will include 4 work sessions spread out over approximately a 2-year period, beginning in spring of 2019. Two of those work sessions will be at regional workshop locations, and 2 work sessions will be conducted remotely with shared screen.
