Residential Energy Retrofit Savings Evaluations from 2007-2012

State of New York data compares contractor-estimated and meter-evaluated energy savings for a subset of home retrofit projects completed between 2007 and 2012. It includes project details like Contractor ID, Project County, and Total Project Cost. The dataset was created to support the deployment of an open-source energy efficiency meter.

Use Cases

• Analyze the discrepancy between Estimated Annual kWh Savings and Evaluated Annual Electric Savings (kWh) to calibrate energy modeling software.
• Model Evaluated Annual Gas Savings (MMBtu) against home attributes like Size of Home, Year Home Built, and Climate Zone.
• Assess program cost-effectiveness by correlating Total Project Cost and Total Incentives with metered savings outcomes.
• Identify regional performance trends by grouping Evaluated Annual Electric Savings (kWh) by Project County or Project ZIP.

Strengths

• Includes direct, weather-normalized meter outputs for key savings metrics like Evaluated Annual Electric Savings (kWh).
• Covers a defined 6-year project completion period from 2007 to 2012.
• Provides third-party validation indicating actual savings are 35% of estimated electric and 65% of estimated gas savings.

Limitations

• Sample size is unspecified and limited to a subset of completed projects.
• Contains contractor-reported estimated savings, which the report indicates significantly overstate actual realized savings.
• Temporal coverage ends in 2012, making the data stale for analyzing current retrofit technologies.
