This CSV dataset provides annual energy performance metrics for non-residential and multifamily buildings in Seattle since 2015. The dataset contains structured energy performance records for buildings exceeding 20,000 square feet, as mandated by the Seattle municipal benchmarking ordinance. It includes critical performance indicators such as ENERGY STAR scores, site and source Energy Use Intensity (EUI), and total greenhouse gas (GHG) emissions. The data is formatted for compatibility with standard analytical software and spreadsheet applications, allowing for granular review of building operational efficiency over time. Each entry captures essential building characteristics necessary for comparative analysis, providing a comprehensive overview of urban energy consumption patterns within the specified jurisdiction.

The download is an 11.5 MB file containing .CSV files.

Professionals can integrate this CSV file into data analysis platforms, GIS software, or custom scripts to perform longitudinal energy audits and comparative building studies. By mapping these values against specific asset types, users can establish performance baselines for new design projects or retrofit feasibility studies. The data facilitates the identification of high-performing building typologies, enabling architects and engineers to align design strategies with municipal sustainability targets and operational efficiency goals using empirical, site-specific information.

This resource is essential for architects, MEP engineers, and sustainability consultants working on urban development projects in Seattle. It serves as a primary reference for establishing energy performance benchmarks during the early design and feasibility stages of multifamily and commercial developments. By leveraging this historical data, project teams can better forecast energy requirements, justify sustainable design interventions, and support compliance reporting. It is frequently used for comparative research in hospitality, healthcare, and office sectors where operational energy efficiency is a key design driver.
