The Clean and Affordable Energy Act of 2008 mandates annual energy and water consumption disclosure for all private buildings over 50,000 gross square feet in the District of Columbia. The District of Columbia Department of Energy and Environment publicly discloses ENERGY STAR Benchmarking results for each building subject to the law, beginning with its second year of data. Data is available in multiple formats including CSV and GEOJSON.
Use Cases
- Benchmark building energy performance against peers nationwide based on the standard metric described.
- Analyze trends in energy efficiency upgrades based on historical consumption data.
- Investigate correlations between building occupancy rates and property values with energy performance.
- Map building energy and water consumption geographically using the geospatial data formats.
- Model policy impacts on building energy use within the District of Columbia jurisdiction.
Strengths
- Data collection is mandated by law for all private buildings over 50,000 gross square feet, suggesting a comprehensive scope.
- Benchmarking uses the industry-standard ENERGY STAR Portfolio Manager tool.
