“…It has also been stated that gender and age are associated with the performance of the actions [23]. This is most likely because they have an impact on energy consumption [52,53] and saving attitudes [54], as well as thermal comfort perception [55][56][57]. Nevertheless, there are few studies on their relationships with the actions themselves, like [58,59].…”

Since occupant behaviour impacts the energy performance of buildings, its study is relevant in order to bridge the performance gap. While the factors influencing occupant behaviour have been established, most studies have focused on those factors that motivate the action, such as environmental and temporal conditions. Contextual factors including spatial and occupant characteristics, which act as action moderators, remain a subject to explore. In this way, this article aims to identify patterns in the occupants' actions in office environments, based on spatial and human factors.A field study, including 514 occupants in 85 office spaces, was carried out in 11 buildings in Concepción, Chile. The results indicate that spatial layout is significantly related to the operation of windows, blinds, and thermostats, but not personal devices. Gender did not influence whether an occupant was active or not and age range was only significant regarding blinds. In shared spaces, there were fewer active occupants and whose acts depend on the perception of opportunity that they have, which is associated with element control distance and occupant age. The findings suggest that the probability that actions occur varies based on spatial and human factors, particularly because these factors affect occupant perception of opportunity.

“…The questionnaire results vary among people with different ages, genders, countries, incomes and so on. In addition, human comfort is a relatively subjective matter [50], [51] and conducting questionnaires involves high-cost and timeconsuming process of data collection. We also cannot make sure the results are correct since they depend on individual participants' responses.…”

“…As a result, there is hardly any well-received commercial product to monitor the real state of human comfort. Human comfort is a relatively subjective matter [50], [51] which is affected by many environmental, psychological and physiological factors. Furthermore, the occupants' perception about comfort may be influenced by numerous external conditions instantly.…”

“…To study human thermal comfort in indoor environment, a few research teams prefer questionnaires to existing comfort models such as PMV and PPD as they believe that comfort is a subjective matter [50], [51]. Nevertheless, most of the research groups choose to apply either the conventional comfort models (covered in section II-A) or their own model derived from training machine learning algorithms to predict thermal comfort.…”

Occupants' comfort perception about the indoor environment is closely linked to their health, wellbeing and productivity. Improvement of comfort level in office buildings has significant positive impacts on both employers and employees. Human comfort in indoor environment usually can be assessed in four aspects: thermal comfort, visual comfort, acoustic comfort and respiratory comfort. In this paper, we present a literature review on the previous research contributions towards studying various aspects of human comfort with a special focus on the respective assessment criteria, data collection methods and data analysis approaches employed by former studies. Previous review work has covered the fundamental concepts associated with human comfort. However, their studies mainly focus on thermal comfort and there is limited work that covers other aspects of comfort. Moreover, few of them discuss how the data is obtained, how to extract useful information from the data and how the data is analyzed. To fill up this gap, this paper conducts the survey from the data-driven point of view. Through the survey, we find that sensor technology has been widely used in the data collection for various types of comfort, while so far the machine learning approaches are mainly applied in the area of thermal comfort study. Finally, some potential future research areas are proposed based on the current status of the research work. The established knowledge in this paper would provide useful insights for engineers or researchers who embark on their research in this area. INDEX TERMS Human comfort, thermal comfort, assessment criteria, data analysis method, sensor technology, machine learning.

A method is proposed to improve work performance through an adequate design of the manufacturing cell along with optimal environmental conditions to contribute to the well-being of the worker. The methodology used was divided into four stages: the first corresponds to the analysis of operations; the second is the analysis of the effect of the design of the manufacturing cell; the third is the evaluation of environmental conditions such as lighting, noise, and temperature to compare them with the official standard and determine if they meet the permitted levels; and the fourth is to conclude and recommend improvements to the manufacturing cell. The method was applied in a company in the automotive industry, where a change was made from a linear cell distribution to an L-shaped distribution, with a 50% reduction in workforce and an increase in the productive time of the worker of 49%. Also, the environmental conditions of the cell comply with the requirements of official standards.
