The COVID-19 pandemic, through governmental 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 air system HVAC settings without efficiency concerns, such 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, and CO2 emissions and operations costs in nine US climate zones — from 0 to 8, south to north latitudes, respectively —, assessed in specifically 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 (4) tend to increase relative energy use intensity by 21.72%, but below that threshold the zones decrease relative energy use intensity by 11.92%.

COVID-19:对美国高层办公建筑能效的影响

COVID-19 大流行通过政府的居家令迫使社会人类行为和相互关系迅速发生变化,以工作环境为目标以保护工人和用户。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空气系统 HVAC 设置,而不考虑效率问题,例如改进流速和对辐照、湿度和温度的过滤。目前的文献一致预测,由于控制 SARS-CoV-2 传播的新措施,能源消耗会增加。研究团队承担了验证先前公布的成果的努力,这些成果适用于美国标准化高层办公楼,由该领域的主要实体定义和设定,通过诉诸基于软件能量分析的方法。该研究比较了标准高层办公楼的能源消耗和 CO2美国九个气候区的排放和运营成本——分别从 0 到 8,南纬到北纬——在 COVID-19 之前和之后的情景之间,特别是在人口最多的城市进行了评估。结果澄清了收集到的知识,解释了混合湿润类型 (4) 以上的气候区往往会增加 21.72% 的相对能源使用强度,但低于该阈值的区域会降低 11.92% 的相对能源使用强度。
