LEED认证的建筑旨在提供可持续和健康的建筑环境。先前的研究表明，关于LEED认证建筑物中的居住者是否比非LEED认证建筑物中的居住者更满意，结果好坏参半。这些研究通常基于对商业建筑的调查或问卷，并受到样本大小和预定义问题结构的限制。由于大多数人在经历COVID-19疫情后会因远程工作的灵活性而花更多时间在家，因此评估住宅楼宇的满意度有利于未来的环境设计和认证体系发展。在这项工作中，我们提出了一种基于自然语言处理的方法进行这种评估。该研究从社交媒体上收集了232栋LEED认证和129栋非LEED认证公寓楼的16，761条在线评论，然后应用主题建模和情感分析来评估居住者的满意度。基于主题模型，我们将在线评论分为三个主题，1）位置和交通，2）运行成本，3）健康和福利。随后的情感分析显示，与非LEED认证的公寓相比，LEED认证的公寓对所有三个主题的满意度都有统计学上的显著提高，但幅度很小或可以忽略不计。在线星星评级和室内环境满意度也出现了“显著但很小或可以忽略不计的上升“。唯一的例外是照明，这是一个大的效果大小被发现在LEED认证的公寓更令人满意。然而，当以租金价格和房产价值进行归一化时，在线星星评级的统计显著性消失。
Leadership in Energy and Environmental Design (LEED) certified buildings aim to offer a sustainable and healthy building environment. Previous studies have shown mixed and inconsistent results on whether occupants in LEED-certified buildings are more satisfied than in non-LEED-certified counterparts. Those studies are usually based on surveys or questionnaires for commercial buildings and were limited by sample size and pre-defined question structures. Since most people would spend more time at home after experiencing the COVID-19 pandemic due to the flexibility to work remotely, assessing the satisfaction with residential buildings benefits future environmental design and certification system development. In this work, we propose a natural language processing-based approach for such assessment. The study collected 16,761 online reviews of 232 LEED-certified and 129 non-LEED-certified apartment buildings from social media, then applied topic modeling and sentiment analysis to evaluate occupants’ satisfaction. Based on topic modeling, we categorized online comments into three topics, 1)location and transportation, 2)running cost, and 3)health andwellbeing.The subsequent sentiment analysis has shown a statistically significant but small or negligible enhancement in the satisfaction occurring in LEED-certified apartments compared to non-LEED-certified ones concerning all three topics. The “significant but small or negligible uptick”has also been found in online star rating and indoor environmental satisfaction. The only exception with a large effect size is lighting which is found to be significantly more satisfying in LEED-certified apartments. Nevertheless, the statistical significance in online star rating disappears when normalized by rent price and property house value.
