The COVID-19 pandemic, through stay-at-home orders, forced rapid changes to social human behavior and interrelations, targeting the work environments to protect workers and users. Rapidly, global organizations, US associations, and professionals stepped in to mitigate the virus's spread in buildings' living and work environments. The institutions proposed new HVAC settings without efficiency concerns, as improved flow rates and filtering for irradiation, humidity, and temperature. Current literature consensually predicted an increase in energy consumption due to new measures to control the SARS-CoV-2 spread. The research team assumed the effort of validating the prior published outcomes, applied to US standardized high-rise office buildings, as defined and set by the key entities in the field, by resorting to a methodology based on software energy analysis. The study compares a standard high-rise office building energy consumption, CO emissions and operations costs in nine US climate zones - from 0 to 8, south to north latitudes, respectively -, assessed in the most populated cities, between the previous and post COVID-19 scenarios. The outcomes clarify the gathered knowledge, explaining that climate zones above mixed-humid type tend to increase relative energy use intensity by 21.72%, but below that threshold the zones decrease relative energy use intensity by 11.92%.
新冠疫情通过居家令，迫使社会人类行为和相互关系迅速改变，目标是工作环境以保护工人和使用者。全球组织、美国协会和专业人士迅速介入，以减轻病毒在建筑物生活和工作环境中的传播。这些机构提出了新的暖通空调设置，而不考虑效率问题，如提高流速以及对辐射、湿度和温度进行过滤。当前文献一致预测，由于控制新冠病毒传播的新措施，能源消耗将会增加。该研究团队假定要努力验证先前发表的成果，这些成果适用于美国标准化的高层办公楼，这些办公楼是由该领域的关键实体所定义和设定的，研究团队采用了基于软件能源分析的方法。该研究比较了美国九个气候区（分别从0到8，即从南到北的纬度）中最人口密集城市里，新冠疫情之前和之后的情景下，一座标准高层办公楼的能源消耗、碳排放和运营成本。研究结果澄清了已收集的知识，解释说混合湿润型以上的气候区相对能源使用强度往往会增加21.72%，但低于该阈值的气候区相对能源使用强度会降低11.92%。
