This aggregated and anonymized dataset of single-family residential building asset attributes and observed average annual energy consumption over the 2-year period from August 2017 through July 2019 is available for Monroe County. The dataset includes more than 55,000 properties from the study’s matched residential dataset that had sufficient data for calculation of average annual energy consumption and could not be uniquely identified in the larger dataset of Monroe County residential parcels or Infogroup data. The data were anonymized by removing all property identifying information including address, parcel identifiers, and parcel size. Attributes such as square footage, building age, and assessed value were then grouped such that no groupings contained fewer than three properties in the Monroe County parcel dataset. This dataset with average annual energy consumption for gas, electric, and total consumption can be used by those interested in further analysis and energy modeling.

In response to the New York State Department of Public Service (DPS) Order Adopting Accelerated Energy Efficiency targets, issued December, 18, 2018, the New York State Energy Research and Development Authority (NYSERDA) contracted with Stone Environmental, Inc to conduct an Asset Data Matching Pilot in Monroe County to analyze building asset data, utility usage data, and NYSERDA program data for single family residential buildings. The objective of the study was to analyze publicly available data along with two years of utility usage data provided by Rochester Gas and Electric (RG&E) to provide information and data to the market to help reduce customer acquisition costs for adoption of energy efficiency measures and to better understand the ability to use building asset data to determine energy efficiency.

As part of the American Recovery and Reinvestment Act, NYSERDA administered an $18.7 million residential high-efficiency appliance rebate program called New York's Great Appliance Swap Out. Under the approved U.S. Department of Energy plan, customers purchasing appliances qualified for a rebate of $75 ($105 with documented recycling) for ENERGY STAR qualified refrigerators, $75 ($100 with documented recycling) for clothes washers and $50 ($75 with documented recycling) for freezers. $500 rebate ($555 with documented recycling) were also available for high-efficiency dishwashers, clothes washers and refrigerators that meet CEE super efficiency levels when they were purchased as part of a three-appliance package. The plan was approved by the DOE on December 1, 2009. The program was launched February 12, 2010 and closed March 4, 2011 after processing over $16.58 million in rebates

The New York State Energy Research and Development Authority (NYSERDA), in collaboration with the New York State Department of Public Service (DPS), conducted a statewide residential baseline study (study) from 2011 to 2014 of the single-family and multifamily residential housing segments, including new construction, and a broad range of energy uses and efficiency measures.The study includes 3 separate study sections:1. HVAC: This dataset includes data from 47 completed Heating Ventilation and Air Conditioning (HVAC) contractor surveys. The survey sample was stratified by the size of the HVAC contractor company: 28 survey completes for small companies (defined as having 1-10 employees) and 19 survey completes for large companies (defined as larger than 10 employees.) The surveys focused on employer or company information, sales of energy efficient HVAC equipment, installation practices, training, and experience with NYS energy efficiency programs.2. Multifamily Owner/Manager (MOM): This dataset includes data from 219 completed Multifamily owner and manager surveys. The types of data collected during the survey cover property characteristics, heating and cooling equipment, water heating equipment, tenant appliances, lighting, purchasing decision, common areas, clothes washing and drying, and miscellaneous equipment. The data is segmented to cover both common space equipment and, to the degree possible, tenant-unit equipment, such as refrigerators or clothes washers that are included in the rental by the building ownership.3. Single/Multifamily Occupant (SMO): This dataset includes 2,982 single-family and 379 multifamily occupant survey completes for a total of 3,361 responses. The survey involved 2,285 Web, 1,041 telephone, and 35 mini-inspection surveys. The survey collected information on the following building characteristics: building shell, kitchen appliances, heating and cooling equipment, water heating equipment, clothes washing and drying equipment, lighting, pool and spa equipment, small household appliances, miscellaneous energy consuming equipment, as well as behaviors and characteristics of respondents.

To reduce the energy burden on income-qualified households within New York State, NYSERDA offers the EmPower New York (EmPower) program, a retrofit program that provides cost-effective electric reduction measures (i.e., primarily lighting and refrigerator replacements), and cost-effective home performance measures (i.e., insulation air sealing, heating system repair and replacments, and health and safety measures) to income qualified homeowners and renters. Home assessments and implementation services are provided by Building Performance Institute (BPI) Goldstar contractors to reduce energy use for low income households. This data set includes energy efficiency projects completed since January 2018 for households with income up to 60% area (county) median income.

D I S C L A I M E R: Estimated Annual kWh Savings, Estimated Annual MMBtu Savings, and First Year Energy Savings $ Estimate 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 impact analysis indicate that, on average, actual savings amount to 54 percent of the Estimated Annual kWh Savings and 70 percent of the Estimated Annual MMBtu Savings. The analysis did not evaluate every single project, but rather a sample of projects from 2007 and 2008, so the results are applicable to the population on average but not necessarily to any individual project which could have over or under achieved in comparison to the evaluated savings. The results from the impact analysis will be updated when more recent information is available. Some reasons individual households may realize savings different from those projected include, but are not limited to, changes in the number or needs of household members, changes in occupancy schedules, changes in energy usage behaviors, changes to appliances and electronics installed in the home, and beginning or ending a home business.

The results from the impact analysis will be updated when more recent information is available. Many factors influence the degree to which estimated savings are realized, including proper calibration of the savings model and the savings algorithms used in the modeling software. Some reasons individual households may realize savings different from those projected include, but are not limited to, changes in the number or needs of household members, changes in occupancy schedules, changes in energy usage behaviors, changes to appliances and electronics installed in the home, and beginning or ending a home business.
