“…The results of the study showed a direct relationship between a high airborne mold, TVOC and the negative health perception of the building’s staff. Similarly, the study in [ 59 ] features case studies of offices in Denmark. In [ 60 , 61 ], the authors deal with noise analysis in residential buildings.…”

To improve buildings and their characteristics, the feedback provided directly by users is generally fundamental in order to be able to adapt the technical and structural functions to the well-being of users. The post-occupancy evaluation (POE) fits perfectly into this context. The POE, through qualitative and quantitative information on the interior environment, makes it possible to identify the differences between the performances modeled in the design phase and the real performances experienced by the occupants. This review of 234 articles, published between 2006 and 2022, aims to analyze and compare the recent literature on the application of the POE methodology. The aim was to provide both a qualitative and quantitative assessment of the main factors that comprise the indoor environmental quality (IEQ). The study highlighted the factors that comprise the quality of the indoor environment, as well as the variables that are usually analyzed to describe the well-being of the occupants. The results suggested which are the most common approaches in carrying out POE studies and will identify the factors that most influence the determination of the good quality of an indoor environment.

“…Moreover, studies confirm that there exists a direct correlation between higher temperature levels and IAQ dissatisfaction during the pandemic (e.g., [22,23]). An experimental study by [24] emphasize that a high temperature in indoor spaces increases VOC (volatile organic compounds) emissions, mostly driven by chemically-produced building materials, which result in poor IAQ, suggesting that occupant feedback on IAQ occur more in the summer time, followed by the spring and winter.…”

Despite challenges, the COVID stay-at-home has provided opportunities to reveal unforeseen complexities within built environments, particularly from indoor health lenses, that had not been sought before the pandemic. This research aimed to evaluate occupants’ feedback on impacts of the stay-at-home on the indoor air quality (IAQ) perception in buildings nationwide in the U.S. during the first year of the pandemic (2019) and compare it with the baseline (2019). We used geo-tagged big textual data obtained from Twitter platform and developed Natural Language Processing (NLP) models based on Sentiment Analysis (SA) approach to compute the occupant feedback for the two consecutive years. We built the SA models through developing a six-step workflow, including data acquisition; data cleaning; text tokenization; analysis; accuracy evaluation; and data visualization and mapping. We used the QDAP dictionary and nrc lexicon to develop the SA models. We also developed automation scripts to improve the simulation performance. Results illustrate that occupants’ complaints on IAQ increased during 2020 compared with the baseline (2019). Findings further suggest that occupants with less access to operative Heating, Cooling, and Air Conditioning (HVAC) systems posted more dissatisfied feelings on Twitter. This research aids decision-makers to better understand the impacts of lockdown on occupants’ health experience to rethink the design and operation of buildings in a way to promote human-centered design and improving building resilience against future pandemics.
