Problem Statement: Understanding urban energy dynamics, particularly energy use in buildings, is a critical component of addressing climate change in cities.

Research Objectives: This project continues a long-term research partnership between the PI and MOS to analyze annual building energy and water benchmarking data. Our goal is to provide a broad

Background/Context: Energy use in buildings accounts for approximately 80% of all of New York City’s energy consumption and carbon emissions. In an effort to improve its sustainability and efficiency, the City adopted an ambitious goal of reducing carbon emissions by 80% by the year 2050. The New York City Mayor’s Office of Sustainability (MOS) is responsible for implementing this plan, which calls for major reduction in building energy use (The City of New York, 2016). The annual Benchmarking report is the flagship study of building energy use in NYC, and has been implemented in several other major U.S. cities.

Methods: We begin by cleaning and merging the Local Law 84 benchmarking data, Local Law 87 energy audit data, and NYC PLUTO property data. These data account for 23,000 buildings, and more than 45% of the total energy consumption in NYC. Our cleaning processes identifies, corrects, and, as necessary removes errors and outliers caused by self-reporting of data and misidentification of individual buildings. We then analyze energy use by a range of building classifications, as well as conduct time series analysis of six-years of energy data. We calculate and visualize energy conservation measure recommendations, including energy savings and cost savings potentials across office, multifamily, and other building types.

Expected Results and Outputs: We will produce a detailed analysis and commentary to be published by the Mayor’s Office. In addition, our analysis and cleaned data will be available through the NYC Energy and Water Performance Map ( , created by the PI.
