2015年，建筑对环境有很大影响，消耗了美国40%的能源和70%的电力。建筑是一个复杂的系统，但建筑、工程和施工（AEC）专业人员在执行工作时往往缺乏正式的入住后反馈流程，该流程告知建筑性能目标的有效性和预期的用户（住户）体验。本文的目的是帮助弥补目前阻碍AEC专业人员做出可实现设计决策的入住后性能知识缺口。从历史上看，在能源消耗的背景下，建筑和服务系统一直处于主导地位。通过建筑能源法规和联邦效率指令，自上而下的积极外壳和服务系统要求正在迅速将住宅建筑中的负荷从传统负荷转移到单独的设备负荷，如热水和其他电力负荷（MEL）。 本研究利用两个位于混合潮湿气候中的描述性和探索性案例研究，评估1）低负荷住宅建筑中变频驱动热泵的模拟与实测性能，以及2）实际天气与模拟标准气候对全年能耗的影响。数据收集自两个全电力、低负荷、经济适用房开发项目，这些开发项目的主要住户是老年居民。数据包括模拟和多年能源使用数据以及建筑技术数据。初步调查结果表明，a）加热和冷却是水加热和MELs的二次负荷，b）天气对年份没有统计上的显著影响- 在这些案例研究的调查样本中，收集到每年的能源使用数据。引文:2018年冬季会议，伊利诺伊州芝加哥，会议论文

Buildings have a large impact on the environment consuming 40% of U.S. energy and 70% of U.S. electricity in 2015. Buildings are complex systems,yet architecture, engineering, and construction (AEC) professionals often perform their work lacking a formal post-occupancy feedback process thatinforms the efficacy of goals for building performance and the anticipated user (occupant) experience. The aim of this paper is to contribute to closing thepost-occupancy performance knowledge gap hindering AEC professionals today to make achievable design decisions. Historically, buildings have beenenclosure and service system dominated in the context of energy consumption. Aggressive, top-down enclosure and service system requirements throughbuilding energy codes and federal efficiency mandates are quickly shifting loads in residential buildings away from traditional loads toward individualappliance loads such as water heating and miscellaneous electric loads (MELS). This study utilizes two descriptive and exploratory case studies locatedin a mixed-humid climate to evaluate 1) simulated versus measured performance of inverter-driven heat pumps in low-load residential buildings and 2)the impact of actual weather versus simulated standard climate on year-to-year energy consumption. Data is collected from two, all electric, low-load,affordable housing developments that have senior residents as their primary occupants. Data include simulated and multi-year energy use data as well asbuilding technology data. Preliminary findings suggest that a) heating and cooling are secondary loads to water heating and MELs and b) weather doesnot have a statistically significant impact on year-to-year energy use data within the investigated samples of these case studies.
