New York Residential Energy Efficiency Projects with Income-Based Incentives

Over 35,000 projects document energy efficiency upgrades in one-to-four unit homes across New York State, beginning in 2010. The data is compiled by the New York State Energy Research and Development Authority (NYSERDA) from its Green Jobs-Green NY program. It includes contractor-reported savings estimates, project costs, and detailed information on home characteristics and incentives.

Use Cases

• Analyze the relationship between `Year Home Built` and `Estimated Annual kWh Savings` to identify which vintage homes benefit most from retrofits.
• Model `Total Incentives` as a function of `Customer Type` and `Pre-Retrofit Home Heating Fuel Type` to assess program targeting.
• Predict `First Year Energy Savings $ Estimate` using features like `Size of Home`, `Measure Type`, and `Number of Units`.
• Perform geospatial analysis of project density and `Total Project Cost` using the `New Georeferenced Column`, `Project County`, and `Project Zip`.
• Investigate the adoption rate of specific `Measure Type` installations across different `Electric Utility` and `Gas Utility` service territories.

Strengths

• Includes over 35,000 project records from November 2010 onward.
• Contains 30 columns detailing technical, financial, and geographic attributes of each retrofit.
• Third-party analysis validated the accuracy of estimated savings, providing correction factors (35% for kWh, 65% for MMBtu).

Limitations

• Reported savings (`Estimated Annual kWh Savings`, `Estimated Annual MMBtu Savings`) are modeled estimates, not actual meter measurements, with known average realization rates.
• The impact evaluation for savings estimates is based on a sample from 2007-2008, which may not reflect current project performance.
• Data completeness for all 30 columns across all 35,000+ rows is not guaranteed.
