New York City Municipal Building Solar Potential Assessments

Municipal building assessments evaluate solar photovoltaic potential for New York City-owned structures exceeding 10,000 square feet. The Department of Citywide Administrative Services (DCAS) prepared this data under Local Law 24 of 2016, with the 2022 report representing the fourth biennial assessment.

Use Cases

• Identify solar-ready buildings by filtering on Roof Condition and Roof Age columns.
• Prioritize projects by ranking Estimated Annual Energy Savings and Upfront Project Cost.
• Analyze geographic equity of solar potential using Environmental Justice Area and Borough fields.
• Estimate carbon impact by calculating total Estimated Annual Emissions Reduction across Agency groups.
• Correlate building size and energy use via Total Gross Square Footage and Percentage of Annual Electricity Consumption.

Strengths

• Includes 30 distinct columns covering technical, financial, and geographic attributes.
• Contains precise geospatial identifiers such as Latitude, Longitude, BBL, and BIN.

Limitations

• Sample data unavailable, preventing verification of data distributions and null values.
• Unknown row count limits understanding of dataset scale and building coverage.
