Maximize the Value of Each Existing Utility Meter
Developing a clear data picture from existing meters might be more valuable than installing a thousand new ones. The proliferation of new sensors should not outpace our efforts to take action using existing data streams.
The first part of this talk will describe an effort to develop better analytics using data from an existing electrical meter in collaboration with Microsoft and OSIsoft. This single meter records power use for a parking structure, exterior lights, water pumps and several electrical car chargers. The team developed a method to process the meter data with machine learning algorithms to discover, in real time, which loads are on and calculate their energy usage. We will describe training the model, data flow, and the machine learning algorithm, and show a proof of concept app that uses the algorithm to show availability of car chargers from multiple vendors. We will explain extensions of the model for a more complete deployment and its broader use in related applications.
The second part of the talk will show the UC Davis Water Dashboard, which used existing operational water meter data to publicly communicate campus progress toward achieving the campus 20% water reduction goal. The real-time portion of the dashboard uses PI Web API and the monthly reporting data supports the use of PI Manual Logger. The public display of existing data helped define ownership for campus water use and created healthy peer pressure to help us meet our conservation goals."
UC Davis Utilities
David Trombly is a Data Scientist at UC Davis Utilities, where he functions as a PI System administrator, supports metering and dashboard efforts, participates in UC-wide sustainability and alternative energy initiatives, and manages data science projects. Before joining UC Davis, he provided air quality environmental consulting to industries including oil and gas production and refining, mining, metals, construction, and paper. David has a PhD in Chemical Engineering from University of Texas at Austin and a BS in Chemical Engineering from UC Davis.
David Phillips is the Director of Utilities for UC Davis and has been running the campus city-scale water, waste, and energy systems for over 20 years. Developing strategies to cost-effectively accomplish campus sustainability goals is a primary focus of his position. Recent projects include contracting for a 70-acre on-campus solar power plant, constructing an innovative on-site waste treatment system that diverts 25% of campus waste, and partnering with local agencies to develop a shared treated surface water supply. In 2007, David and his colleague Michael Fan received the Gascoigne Medal from the Water Environment Federation for their work describing how oxygen sensors and a feedback control system can optimize wastewater treatment performance while minimizing energy use. David and his staff are currently working to refine an electrical meter disaggregation process to track and report status for municipal infrastructure systems, develop innovative zero net energy displays, and create automated techniques to tune the campus network of 1,600 adaptive exterior lighting fixtures. David has a B.S. degree in Civil Engineering from UC Davis and is a California-registered professional engineer.
