在美国，建筑消耗了40%的能源，这比包括交通和工业在内的美国经济的任何其他部门都要多。这些能源的大部分用于建筑物的照明、空间供暖、制冷、通风和水加热。众所周知，碳排放量与能源消耗成正比。提高建筑效率成为减少碳排放最简单、最直接、最具成本效益的方法之一。本文重点研究了基于模拟的不同节能措施的全国节能分析，以提高建筑节能性能。这项研究包括19种不同的ECM，在16个不同的气候区对美国11种不同的商业建筑类型进行了模拟。 使用整个建筑模拟程序EnergyPlus进行模拟。DOE PNNL的商业原型建筑模型被用作基线。使用脚本自动修改模型输入文件，以与19个不同的ECM合并。基线基于ASHRAE标准90.1–2010。总共进行了4400次模拟，以研究全国的节能潜力。本文介绍并讨论了这19种建议的ECM的细节和相应的节能潜力。引文:2018年冬季会议，伊利诺伊州芝加哥，会议论文

Buildings consumed 40% of the energy in the United States, which is more than any other sectors of the U.S. economy, including transportation and industry. The majority of this energy was used for lighting, space heating, cooling, ventilation, and water heating in the buildings. It is well known that the carbon emission is proportional to the energy consumption. Enhancing building efficiency becomes one of the easiest, most immediate and most cost-effective ways to reduce carbon emissions. This paper focuses on the simulation-based nationwide energy savings analysis of different energy conservation measures (ECMs) to enhance building energy performance. The study includes 19 different ECMs, which were simulated in 16 different climate zones for 11 different commercial building types in the U.S. Simulations were conducted using a whole building simulation program, EnergyPlus. DOE PNNL’s commercial prototype building models were used as the baselines. Model input files were automatically modified to incorporate with 19 different ECMs using scripts. The baselines are based on ASHRAE Standard 90.1 – 2010. A total of 4,400 simulations were generated to study the nationwide energy savings potentials. The details of these 19 proposed ECMs and the corresponding saving potentials are presented and discussed in this paper.
