IMPORTANT! PLEASE READ DISCLAIMER BEFORE USING DATA. This dataset backcasts estimated modeled savings for a subset of 2007-2012 completed projects in the Home Performance with ENERGY STAR® Program against normalized savings calculated by an open source energy efficiency meter available at https://www.openee.io/. Open source code uses utility-grade metered consumption to weather-normalize the pre- and post-consumption data using standard methods with no discretionary independent variables. The open source energy efficiency meter allows private companies, utilities, and regulators to calculate energy savings from energy efficiency retrofits with increased confidence and replicability of results. This dataset is intended to lay a foundation for future innovation and deployment of the open source energy efficiency meter across the residential energy sector, and to help inform stakeholders interested in pay for performance programs, where providers are paid for realizing measurable weather-normalized results.

Normalized Savings using open source OEE meter. Several data elements, including, Evaluated Annual Elecric Savings (kWh), Evaluated Annual Gas Savings (MMBtu), Pre-retrofit Baseline Electric (kWh), Pre-retrofit Baseline Gas (MMBtu), Post-retrofit Usage Electric (kWh), and Post-retrofit Usage Gas (MMBtu) are direct outputs from the open source OEE meter.

Home Performance with ENERGY STAR® Estimated Savings. Several data elements, including, Estimated Annual kWh Savings, Estimated Annual MMBtu Savings, and Estimated First Year Energy Savings represent contractor-reported savings derived from energy modeling software calculations and not actual realized energy savings. The accuracy of the Estimated Annual kWh Savings and Estimated Annual MMBtu Savings for projects has been evaluated by an independent third party. The results of the Home Performance with ENERGY STAR impact analysis indicate that, on average, actual savings amount to 35 percent of the Estimated Annual kWh Savings and 65 percent of the Estimated Annual MMBtu Savings.

IMPORTANT! PLEASE READ DISCLAIMER BEFORE USING DATA. This data set includes modeled savings for specific energy efficiency measures by measure category and measure sub-category for a subset of 2007-2012 completed projects in the Residential Existing Homes (One to Four Units) Energy Efficiency Projects with Income-based Incentives by Customer Type: Beginning 2010 (https://data.ny.gov/d/assk-vu73) dataset. It is anticipated that this dataset will be most helpful when used in conjunction with the project-level dataset, Residential Existing Homes (one to Four Units) Energy Efficiency Meter Evaluated Project Data: 2007-2012 (https://data.ny.gov/d/5vqm-4rpf). When used together these datasets backcast estimated measure-level savings and project-level estimated (modeled) savings against normalized savings calculated by an open source energy efficiency meter available at: https://www.openee.io/.

This dataset includes the following data points for a subset of projects completed in 2007-2012: Project ID, Measure ID, Measure Category, Measure Sub-category, Measure Cost ($), Measure Quantity, Measure Life, Measure SIR, Measure Incremental Energy Savings (MMBtu), Measure Estimated Annual Electric Savings (kWh), Measure Estimated Annual Energy Savings (MMBtu), Measure Estimated Annual Natural Gas Savings (MMBtu), Measure Estimated Oil Savings (MMBtu), Measure Estimated Propane Savings (MMBtu), Measure Estimated Coal Savings (MMBtu), Measure Estimated Kerosene Savings (MMBtu), Measure Estimated Pellets Savings (MMBtu), Measure Estimated Wood Savings (MMBtu).
