Seattle Building Energy Benchmarking Records 2015-2024

City of Seattle's Building Energy Benchmarking Program requires annual reporting for non-residential and multifamily buildings larger than 20,000 square feet. This dataset contains disclosed performance records from 2015 to 2024, covering metrics like Energy Use Intensity (EUI) and greenhouse gas emissions. It is maintained by the City's Office of Sustainability and Environment.

Use Cases

• Analyze trends in Energy Use Intensity (EUI) and greenhouse gas emissions across Commercial Buildings and Multifamily Buildings from 2015 onward.
• Model the relationship between building size, energy sources (Electricity, Gas, Steam), and reported Fossil Fuel consumption.
• Compare energy performance benchmarks, such as Energy Star scores, between different building types over the 9-year period.

Strengths

• Provides a 9-year time series of energy performance data from 2015 to 2024.
• Covers a specific and regulated segment of the building stock: structures larger than 20,000 square feet.
• Includes multiple energy-related metrics like EUI and greenhouse gas emissions for analysis.

Limitations

• Data is limited to buildings in Seattle, which may not be representative of other regions.
• The dataset only includes buildings above a specific size threshold, excluding smaller commercial and all residential properties.
• Sample data and specific column definitions are unavailable, complicating initial data exploration.
