Data Quality and Reliability Metrics for Building Energy Disclosure Data

 

Research Focus

Buildings

Primary Subject Area

Energy and Sustainability

This project develops a methodology for evaluating and improving the data quality and analysis of benchmarking data from privately- and publicly-owned buildings. We utilize machine learning tools to support the District of Columbia Department of Energy and Environment in improving the quality of building energy data collected through its mandatory building rating and disclosure policy. Using energy disclosure data from calendar year 2013, we present a new data quality rating algorithm and grading system  known as the Data Integrity and Quality (DataIQ) score  to rank the relative reliability of reported data and provide a tool to improve the identification and prediction of data quality concerns going forward. We apply non-parametric statistical anomaly detection techniques to identify data quality and reliability concerns in self-reported building energy benchmarking data. This approach creates a foundation for more robust and precise analysis of city energy data that can provide policymakers with additional insight to improve the reliability of building benchmarking data analysis and inform the design of data-driven energy efficiency policies.

Prof. Kontokosta brings training urban planning, data science, economics, and systems engineering to the data-driven study of cities.

Professor Constantine E. Kontokosta, PhD, PE, is an Assistant Professor of Urban Informatics in the Department of Civil and Urban Engineering and the Center for Urban Science and Progress (CUSP) at New York University, is the Director of the Urban Intelligence Lab, and is the Deputy Director for Academics at CUSP. He holds a faculty appointment as Visiting Professor of Computer Science at the University of Warwick, and is affiliated faculty at the NYU Wagner School of Public Service and Marron Institute for Urban Management. He is also the Principal Investigator and Head of the CUSP Quantified Community research facility, a groundbreaking project underway at five districts in New York City – at the Hudson Yards development in New York City; in Lower Manhattan; at Governor’s Island, and in Red Hook and Brownsville, Brooklyn – that is building sensor-enabled urban neighborhoods to study the impact of the built environment on well-being and human behavior. As one of the first faculty to join CUSP, Constantine is part of the CUSP founding leadership team, setting the Center’s strategic priorities and leading the design and implementation of its academic programs in urban data science, growing from just two to over 50 faculty and staff and 100 graduate students in three years. He serves as Faculty Engineer-in-Residence at the NYU Tech Incubators, where he mentors cleantech and smart city start-up companies from early stage idea refinement to technology demonstration and deployment. He is a 2017 recipient of the NSF CAREER award for his research in urban informatics for smart, sustainable cities.

Dr. Kontokosta‘s research lies at the intersection or urban planning, data science, and systems engineering, focusing on using big data and new sensing technologies to better understand the dynamics of physical, environmental, and social systems in the urban environment. His work has been published in leading academic journals in fields including science, economics, urban policy and planning, and engineering, and has two forthcoming books, one on data-driven city operations and planning and the other on the subject of big data and urban sustainability. He collaborates with numerous city agencies in the U.S. and internationally on issues of urban sustainability and resilience policy and planning and city operations, including a multi-year effort to lead data analysis on building energy efficiency with the NYC Mayor’s Office of Sustainability. Dr. Kontokosta’s work has been featured in the Wall Street JournalNew York TimesCNN, NPR, Fast CompanyCityLab, Bloomberg NewsFinancial Times, APS Physics, and ASCE’s Civil Engineering Magazine, among other national and international media outlets.

Dr. Kontokosta holds a Ph.D., M.Phil, and M.S. in Urban Planning, specializing in urban economics and econometrics, from Columbia University, a M.S. in Real Estate Finance from New York University, and a B.S.E. in Civil Engineering Systems from the University of Pennsylvania. He has received research funding from the MacArthur Foundation, the Sloan Foundation, the National Science Foundation, Siemens Corp., CBRE Group, Inc., and the U.S. Department of Housing and Urban Development, among others. Kontokosta has won the IBM Faculty Award, Goddard Junior Faculty Fellowship, the Google IoT Research Award, and NYU’s Award for Teaching Excellence. He is also a recipient of the C. Lowell Harriss Dissertation Award, the Columbia GSAS Dissertation Award, the Charles Abrams Award for Research in Social Justice, the Best Paper Award at the Bloomberg Data for Good Exchange in 2015, and has been named a Fulbright Senior Scholar in Urban Planning.

Dr. Kontokosta is a licensed Professional Engineer, a member of the American Institute of Certified Planners, a USGBC LEED Accredited Professional, and has been elected a Fellow of the Royal Institution of Chartered Surveyors (RICS).  In addition, he has served on the NYC Mayor’s 80×50 Task Force, as Vice Chair of the Suffolk County Planning Commission, and on the Boards of the UNEP SBCI and the Royal Institution of Chartered Surveyors. He is an accomplished real estate entrepreneur, and, together with his brother, Michael Kontokosta, designed, built, and owns Kontokosta Winery, the Harborfront Inn, and Cove Place Inn, all on the North Fork of Long Island, as well as numerous properties in New York City and the East End.
