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！在使用数据之前，请仔细阅读免责声明。住宅现有住宅计划是一项市场转型项目，该项目采用建筑性能研究所（BPI）金星级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整体房屋方法，以减少该州现有的一至四户家庭和低层多户住宅建筑物的能源消耗，并捕捉供暖燃料和电力相关的节省。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%的家庭提供援助补贴，以便安装符合资格的节能改进措施，包括建筑外壳措施、高效供暖和冷却措施、能源之星家电和照明。

免责声明：估计的年度千瓦时节省量、估计的年度百万英热单位节省量和第一年能源节省费用估计（美元）代表承包商根据能源建模软件计算得出的节省量，而非实际实现的能源节省量。估计的年度千瓦时节省量和估计的年度百万英热单位节省量对于项目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，实际节省量相当于估计年度千瓦时节省量的35%和估计年度百万英热单位节省量的65%。分析并未评估每个单独的项目，而是评估了2007年和2008年的一部分项目样本，因此结果适用于平均情况，但不一定适用于任何单个项目，该项目可能与评估的节省量相比有过或不足的表现。影响分析的结果将在更多近期信息可用时进行更新。许多因素会影响估计节省量实现的程度，包括节省模型和建模软件中使用的节省算法的正确校准。个别家庭可能实现的节省量与预测不同的一些原因包括，但不限于，家庭成员数量或需求的变化、入住时间表的变化、能源使用习惯的变化、家中安装的家电和电子设备的变化，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，以更准确地预测节省量。如需更多信息，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。
