David Farnsworth spoke at the National Association of Regulatory Utility Commissioners (NARUC) Winter Committee Meetings as part of a Water Committee Panel entitled “Encouraging Building Owner Investment in Water Efficiency through Customer Data Aggregation.” Drawing on a recent paper he co-authored, he provided a practical perspective on the potential for water and energy cost savings in the building sector, the role of benchmarking and customer data aggregation policies, and how utility commissions could make available water and energy use data needed by building owners to invest in building improvements. Mr. Farnsworth encouraged regulators to consider developing rules that require data aggregation by all utilities, to explore the best administrative approach for doing so, and to ensure that they can protect customer privacy.
