Summary: Recent studies have shown that physiological responses of occupants can serve as indicators of indoor environmental quality (IEQ), leading to a growing demand for wearable devices to measure these responses. While previous reviews have discussed physiological responses affected by IEQ and corresponding measuring devices, a comprehensive review on proper measuring methods for future research and development is still necessary. This study reviewed measuring methods for physiological responses related to IEQ and proposed directions and guidelines for improving existing wearable devices and developing future ones.

Summary: This paper provides a comprehensive review of 25 studies on the development of IEQ evaluation models in commercial buildings. The studies differentiate between objective and subjective measurement approaches, as well as three types of IEQ models. The analysis discusses five commonly used methods and evaluates the interaction effects and relative contributions of IEQ factors. The paper proposes five key criteria for developing quality IEQ models and presents a ranking and scoring system for their evaluation.

Summary: Previous studies have focused on improving indoor environmental quality (IEQ) through various interventions, but few have investigated what motivates individuals to seek better IEQ. This study examines how occupants' perceptions of IEQ can influence their behavioral changes in improving IEQ. A living-lab-based empirical study conducted in a green building in Hong Kong showed that objective IEQ information can help previously indifferent occupants understand and create a more comfortable working environment. This study combines data-driven IEQ reports, questionnaire surveys, and statistical analysis to provide insights on improving occupants' perceptions and motivating participation for IEQ improvement.

Summary: It is important to provide building users with the ability to adjust indoor-environmental conditions due to varying needs and preferences. However, there is a lack of specific guidance on incorporating user control considerations in building design and operation processes, as revealed by a review of indoor-environmental quality standards.

Summary: Most studies on the impact of indoor environmental quality (IEQ) on task performance assume a direct effect, but this study explores the indirect effects through mediating variables. The results show that IEQ does not directly affect task performance, but indirectly influences it through dominance resulting from skin conductance. Hot and humid thermal environment and unpleasant indoor air quality increase skin conductance, leading to passive emotions and decreased task performance. Future smart offices should consider human bio-signals and emotions in managing IEQ.

Summary: This study developed a novel wearable micro air cleaner to provide personalized protection to occupants. The device achieved a protective efficiency of 77% for mouth breathing and 63% for nasal breathing, while also offering satisfactory thermal comfort experience at indoor air temperatures higher than 25 degrees C. The study also developed data-driven thermal comfort models that outperformed 0.9 in terms of performance. Overall, the wearable micro air cleaner could be an effective occupant-oriented indoor environmental control method.

Summary: This study aims to explore the effects of combinations of indoor air temperature and bedding system on sleep thermal sensation and sleep quality. The results showed that matching the bedding system and indoor temperature to achieve thermal neutrality led to the highest sleep efficiency and deep sleep proportion. Deviating from thermal neutrality resulted in a reduction in sleep efficiency and deep sleep proportion. Therefore, when creating a sleep thermal environment, it is important to consider the suitable matching of indoor temperature and bedding system.

Summary: Occupant satisfaction is influenced by the interaction and combined effects of multi-domain indoor environmental quality (IEQ) in buildings. Existing literature reviews on IEQ have limitations, including limited scope of reviewed interactions and lack of quantitative discussion on overall satisfaction. This study addresses these gaps by selecting relevant publications on four IEQ domains and reviewing their findings. The study shows inconsistent findings on IEQ interactions, highlights the importance of personal overall satisfaction models, and suggests the need for a global IEQ database and non-linear modeling approaches.

Summary: Traditional post occupancy evaluation poses challenges in understanding occupant dissatisfaction with indoor environmental quality due to predefined questionnaires and time-consuming data collection. However, leveraging human perception and text mining can reveal relationships between environmental conditions and occupant dissatisfaction. This paper analyzes 1.2 million Booking.com reviews to identify prevalent complaints, investigate climate distributions, and quantify the social benefits of indoor environmental quality.

Summary: In this study, weighting schemes proposed in the literature between 2002 and 2018 were examined, focusing on occupant well-being and considering the combined effects of multiple environmental factors. The results of the study can be useful for those dealing with holistic building design approaches, where considerations for occupants' well-being, energy performance, and building management costs are taken into account.

Summary: The fundamental goal of modern high-performance buildings is to achieve low environmental carbon footprint while securing indoor conditions that promote human health and well-being. This research examined an overall IEQ assessment model through derivation of weighting coefficients for relevant IEQ parameters, and developed a low-cost open-source platform for continuous measurement of these parameters. Results showed that individual weighting coefficients for IEQ parameters differ across building types, and occupants in different types of buildings may have different preferences for these parameters.

Summary: Social housing users are more vulnerable and face specific problems related to poor indoor environment. The current housing model does not meet the diversity of family structures and needs, so it is important to involve residents' perspectives in improving their quality of life. This study analyzes the factors that influence the perceived indoor environmental quality and comfort of public rental housing, and examines the relationship between occupants' perceived comfort and dwelling characteristics.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.

Summary: This paper compares two main approaches to consider uncertainties in model predictive control (MPC) for buildings: robust and stochastic MPC. The results show that compared to a deterministic MPC, the robust MPC increases the electricity cost while providing complete temperature constraint satisfaction, while the stochastic MPC slightly increases the electricity cost but fulfills the thermal comfort requirements.
