To investigate whether TVOC affects cognitive performance in schools, especially in newly constructed or renovated buildings within the first 3 months, a single-blind experiment was conducted in a climate chamber. Then, 33 university students were exposed to three moderate TVOC concentrations: below 100, 1000, and 2000 <i>μ</i>g/m<sup>3</sup>, all emitted by solvent-based paint. Ventilation (30 m<sup>3</sup>/h), temperature (22°C), relative humidity (50%), lighting, and noise levels were maintained at constant values for all exposure conditions. Cognitive performance was measured through reaction speed and accuracy using a computer-based test battery that included 10 randomized tasks; all participants completed the test three times. Participants’ perceptions of the environment were investigated through pretest and posttest questionnaires. The results indicate no statistically significant differences in reaction speed or accuracy were observed between exposure to medium–low (1000) and low (100 <i>μ</i>g/m<sup>3</sup>) TVOC levels. Exposure to a medium–high level of TVOC (2000 <i>μ</i>g/m<sup>3</sup>) significantly reduced task accuracy by 4.9% compared to the low level (100 <i>μ</i>g/m<sup>3</sup>). No statistically significant effect on reaction speed was observed. Participants’ perceptions of air quality were rated significantly worse at both the 1000 and 2000 <i>μ</i>g/m<sup>3</sup> TVOC exposure levels compared to the low level. Overall, no significant differences in cognitive performance were observed between the medium–low and low TVOC exposure levels. Both accuracy in memory tasks and well-being were negatively affected when comparing the medium–high level to the low level of TVOC. These findings highlight the critical need for monitoring and controlling TVOC levels during the early stages of construction and renovation to improve indoor air quality.

Given the significant influence of outdoor air, IAQ requires continuous monitoring across different seasons and extended periods. In this study, IAQ was measured over nearly a year, capturing seasonal variations and long-term trends.

The research investigated how changes in climate history may affect thermal satisfaction in a multifunctional informal study space. The study involved recording temperature and relative humidity data in a computer room over a period of 1 year and assessing environmental conditions using an online survey. Statistical analysis showed that participants’ climate background did not affect their thermal sensation, preference or comfort results but did affect their clothing levels. It was observed that the clothing levels of participants from warmer and cooler climate backgrounds were different from those from climates similar to the Liverpool. This situation can be explained as an example of occupant behaviour to adapt to different climate conditions. The results showed that most participants rated the environment as cool and would have liked to feel warmer, suggesting that the current temperature settings should be reviewed. These temperature settings were determined according to current standards but did not meet the expectations of the occupants. Updating the current standards may therefore have implications for improving occupant comfort and saving energy across the HE building stock.

This perception is deeply rooted in historical fears, despite modern construction practices mitigating many of these risks. Although indoor air quality has only recently gained significant attention, it is a critical determinant of occupant satisfaction, well-being, and health. This paper challenges two prevalent misconceptions about air quality in urban spaces: (1) That indoor air is always cleaner than ambient air, and (2) that poor indoor air is primarily caused by external, ambient sources. By analyzing both indoor and ambient air quality data from four urban office buildings in the US Southeast and Mid-Atlantic region (Atlanta, Charlotte, Durham, and Washington, DC) alongside qualitative feedback, the study reveals that indoor air was only categorized as better than ambient air for 59.2% of working hours during the 12-month period. While indoor air generally performed better than ambient air, significant fluctuations were observed, and in some cases, ambient air was cleaner than indoor air. Furthermore, the data showed that indoor pollution was more often influenced by internal factors, such as building materials, equipment, and occupant activities, rather than by external pollutants. The findings underscore the need for ongoing management of indoor sources of pollution, particularly in high-performance environments.

In a chamber specially developed for particle dispersion tests, we created a defined bioaerosol to study the performance of two methods commonly used in biology and engineering studies: airborne bacterial detection and particulate matter (PM) analysis. A total of five ventilation cases were investigated in which an air curtain, operated at Reynolds numbers Re < 11, 000, shielded the particles in one half of the test chamber from the other half. In two of these five cases, a HEPA filter was also installed to specifically reduce the particle concentration in the test chamber. In addition to active and passive air sampling measurements of bacteria, we took PM measurements in front of, beneath, and behind the air curtain under constant air temperature and relative humidity conditions. The bioaerosol contained nine bacterial species, evenly distributed in artificial saliva. Two species in the bioaerosol, <i>Staphylococcus capitis</i> DSM 111179 and <i>Burkholderia lata</i> DSM 23089<sup>T</sup>, were selected for evaluation due to their antibiotic resistance, which makes them distinguishable from other species. The results show a similar trend in the concentrations of the detected particles and bacteria. The survival rates of the evaluated bacterial species differed; <i>S. capitis</i> exhibited a greater agreement with the PM measurements than <i>B. lata</i> did, which emphasizes the importance of using a various model organism in such experimental setups. We evaluated the effectiveness of the air curtain in reducing particle and bacterial spread, with values reaching up to 66% for both measurement approaches.
