Residential Existing Homes (One to Four Units) Energy Efficiency Projects with Income-based Incentives by Customer Type: Beginning 2010

IMPORTANT! PLEASE READ DISCLAIMER BEFORE USING DATA. The Residential Existing Homes Program is a market transformation program that uses Building Performance Institute (BPI) Goldstar contractors to install comprehensive energy-efficient improvements.  The program is designed to use building science and a whole-house approach to reduce energy use in the State’s existing one-to-four family and low-rise multifamily residential buildings and capture heating fuel and electricity-related savings.  The Program provides income-based incentives, including an assisted subsidy for households with income up to 80% of the State or Median County Income, whichever is higher to install eligible energy efficiency improvements including building shell measures, high efficiency heating and cooling measures, ENERGY STAR appliances and lighting.

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 35 percent of the Estimated Annual kWh Savings and 65 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. 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. Beginning November 2017, the Program requires the use of HPXML-compliant modeling software tools and data quality protocols have been implemented to more accurately project savings.

重要！在使用数据前，请务必阅读免责声明。住宅既有房屋计划是一项市场转型项目，该项目利用建筑性能研究所（BPI）的Goldstar承包商安装全面节能改进措施。该计划旨在运用建筑科学和全屋方法，降低州内现有的一至四户家庭和低层多户住宅建筑能耗，并捕捉供暖燃料和电力相关的节约。该计划提供基于收入的激励措施，包括对收入不超过州或县中位数收入80%的家庭的辅助补贴，以安装合格的节能改进措施，包括建筑外壳措施、高效供暖和冷却措施、能源之星电器和照明。

免责声明：预估年千瓦时节约量、预估年百万英热单位节约量和第一年能源节约美元估算值代表承包商从能源建模软件计算得出的节约量，并非实际实现的能源节约量。预估年千瓦时节约量和预估年百万英热单位节约量的准确性已由独立第三方进行评估。影响分析的结果表明，平均而言，实际节约量约为预估年千瓦时节约量的35%和预估年百万英热单位节约量的65%。分析并未评估每个单独的项目，而是对2007年和2008年的部分项目样本进行了评估，因此结果适用于平均情况，但不一定适用于任何单个项目，该项目可能相对于评估的节约量有超额或不足的表现。当有更多最新信息时，影响分析的结果将进行更新。许多因素会影响预估节约量实现的程度，包括节约模型和建模软件中使用的节约算法的适当校准。个别家庭可能实现的节约量与预测不同，原因可能包括但不限于家庭成员数量或需求的变化、入住时间表的变化、能源使用行为的变化、家庭中安装的电器和电子设备的变化，以及开始或结束家庭业务。自2017年11月起，该计划要求使用符合HPXML规范的建模软件工具，并已实施数据质量协议，以更准确地预测节约量。更多信息，请参阅NYSERDA网站上发布的评估报告：http://www.nyserda.ny.gov/-/media/Files/Publications/PPSER/Program-Evaluation/2012ContractorReports/2012-HPwES-Impact-Report-with-Appendices.pdf。
