Special Issue Information

Dear Colleagues,

People spend more than 90% of their time indoors. Existing studies have shown the effects of indoor environment quality (IEQ) on human comfort, cognitive performance and health. Poor IEQ would make occupants more uncomfortable and less productive. Nowadays, indoor environment quality has been gaining substantial attention. For the increased requirement for high-quality living and working conditions, understanding the mechanism behind the IEQ and human comfort becomes increasingly important.

We are pleased to announce a call for papers for a forthcoming Special Issue in Buildings, dedicated to the comprehensive examination of the profound relationship between IEQ and human comfort. This interdisciplinary initiative seeks to attract academic contributions that reveal the complex dynamics, methodologies, and implications surrounding IEQ and its pivotal role in enhancing individuals' comfort, health and cognitive performance.

We invite researchers, academics, practitioners, and experts in the field of indoor environmental quality to contribute their original and innovative research findings to this significant endeavor.

Papers submitted to this Special Issue will delve into a wide spectrum of IEQ dimensions, including but not limited to indoor air quality, thermal comfort, lighting, acoustics, and ergonomics, shedding light on their intricate relationships with subjective comfort, health and cognitive performance. Furthermore, we encourage contributions that explore the integration of advanced technologies and sustainable design practices as effective tools for optimizing IEQ and enhancing human well-being.

The civil aircraft cabin is enclosed and highly occupied, making it susceptible to a decline in indoor environmental quality. The environmental quality of civil aircraft cabins not only depends on objective factors such as temperature, relative humidity, and the presence of air pollutants such as carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), particle matter (PM), and volatile organic compounds (VOCs) but also the subjective factors pertaining to the perceptions and health symptoms of passengers and crew. However, few studies have thoroughly examined the air quality and thermal comfort parameters that are measured during in-flight testing in airplane cabins, as well as the passengers’ subjective perceptions. In order to evaluate the in-flight thermal comfort and air quality status, this study conducted a review of the recent literature to compile data on primary categories, standard limits, and distribution ranges of in-flight environmental factors within civil aircraft cabins. Following a search procedure outlined in this paper, 54 papers were selected for inclusion. Utilizing the Monte Carlo method, the Predicted Mean Vote (PMV) distributions under different exercise intensities and clothing thermal resistance were measured with the in-cabin temperature and humidity from in-flight tests. Recommendations based on first-hand data were made to maintain the relative humidity in the cabin below 40%, ensure wind speed remains within the range of 0–1 m/s, and regulate the temperature between 25–27 °C (for summer) and 22–27 °C (for winter). The current estimated cabin air supply rate generally complies with the requirements of international standards. Additionally, potential carcinogenic and non-carcinogenic risks associated with formaldehyde, benzene, tetrachloroethylene, and naphthalene were calculated. The sorted data of in-flight tests and the evaluation of the subjective perception of the occupants provide an evaluation of current cabin thermal comfort and air quality status, which can serve as a reference for optimizing indoor environmental quality in future generations of civil aircraft cabins.

Individuals exposed to elevated noise levels experience heightened emotional intensity, leading to increased cognitive disruption and a higher likelihood of accidents. This study seeks to investigate the impact of noise exposure on human cognitive performance, and the moderating role of emotion. Twelve healthy male college-age students underwent exposure to three noise conditions, each characterized by different sound pressure levels and sharpness. Each condition included an initial acoustic/thermal adaption period lasting approximately 40 min, followed by intermittent questionnaire tests and a battery of computerized cognitive tests. Statistical analysis revealed that reducing noise levels proved advantageous, enhancing perceived sound quality, positive emotions, and auditory perception abilities, while concurrently reducing false alerts and accelerating execution speed. Many of these effects were found to be counteracted by elevated sharpness. Correlation analyses and partial least squares structural equation modeling (PLS-SEM) results suggested that human emotions mediate the relationship between noise exposure and cognitive performance. The potential underlying mechanism suggests that negative feelings towards noise contribute to poor emotional states, subsequently influencing cognitive processes and impairing executive function. The outcomes of this study provide valuable insights into the mechanism of noise exposure and its effects on human cognition and subjective perceptions. Full article

Humans are spending more time indoors than ever due to urbanisation and industrialisation, leading to higher electricity consumption in lighting systems. Recent research has demonstrated the significance of maintaining a balance between daylight and electric light to create an ideal learning environment that can significantly impact students’ academic performance. The objective of this study is to analyse the changes in students’ emotional response depending on the type of lighting in the classroom—whether it is daylight, electric light, or a combination of both. A field study was conducted with 521 university students to assess their affective response to the lighting environment inside their classroom. The results show that students prefer a Clear-efficient lighting environment for writing–reading tasks and a Soft-calm atmosphere for using electronic devices. For the paying attention tasks, a combination of daylighting and electric lighting is determined to be the best solution, while for the tasks of discussing–teamwork, students prefer daylighting. Daylighting is found to be the only lighting option that students like. Despite this, students still consider electric lighting and the combination of daylight and electric light adequate for a classroom. The findings of this study may help educators and designers create learning spaces that promote a positive and stimulating student environment by understanding the relationship between the lighting environment and students’ affective responses.
