“…Each office exhibits similar occupational characteristics, furniture, and architecture, with standard office furnishings such as monitors, desks, and chairs (Figure 1). Despite some exceptions with a higher number of occupants (3,4, or 5 people), the average number of occupants per office is one or two people. Each floor accommodates around 70 workers, typically operating from 8 a.m. to 6 p.m.…”

“…Office buildings are a particularly sensitive category as people spend a significant amount of time in them, but as end-users, they often have limited control over ventilation and IAQ. This can lead to discomfort and higher energy consumption [4]. Various studies have focused on assessing IAQ in offices, addressing aspects such as perceived air quality (PAQ) [5], the relationship between IAQ and productivity, and sick building syndrome (SBS) [6], as well as the link between ventilation and energy consumption [7].…”

Building tight for minimizing building energy consumption and related carbon emissions might negatively affect indoor air quality (IAQ) if this is not correctly designed and evaluated during operation. To address this concern, a post occupancy evaluation study was conducted in a recent large office building in the Autonomous Province of Bolzano (Italy). The aim of the study was to collect evidence from a relevant case study and use it as a basis to define a standardized strategy for continuous monitoring of a larger portfolio of office buildings. Additionally, carbon dioxide (CO2), particulate matter (PM2.5, PM10), total volatile organic compounds (TVOC), air temperature, and relative humidity were recorded 24/7 for a 5-week period in winter 2023. Detailed spot measurements of VOCs and aldehydes were also carried out. Perceived air quality (PAQ) was evaluated through satisfaction surveys which covered various factors influencing PAQ including 14 potential sources of dissatisfaction. A cross-modal approach allowed for a comprehensive examination of the different domains (thermal, visual, acoustic, and IAQ) on PAQ. Measured contaminants’ levels were below recommended limits. Overall, participants were neither satisfied nor dissatisfied with PAQ, and possible related sources of dissatisfaction were elements such as the relative humidity. Sick building syndrome (SBS) selfreported symptoms such as dry skin and itchy eyes confirmed potentially too low relative humidity levels.

Thermal comfort is important for buildings, especially in tropical climates. The issue of increasing indoor temperature is influenced by various factors that cause occupants to face thermal discomfort in cafeterias that uses both mechanical and natural ventilation systems. This study aims to determine the perception of occupants and evaluate parameter variations of thermal comfort in the cafeteria of Pagoh Campus Residential College, UTHM Pagoh Branch Campus. This study was conducted through the measurements of subjective and physical parameters. Data collection is carried out in two days, which are weekdays and weekends. This study uses some parameters variation which are thermal sensation vote index (TSV), predicted mean vote index (PMV), predicted percentage of dissatisfaction (PPD), operative temperature (To) and neutral operative temperature (Tneutop) to determine the thermal comfort conditions in the cafeteria. The results shows that the average values of air temperature, mean radiation temperature, relative humidity and air velocity from environmental measurements were 30.2 °C, 30.6 °C, 66% and 0.1 m/s respectively. In addition, PMV and PPD values were 2.0 and 76% from environmental measurements, while 1.36 and 43% from questionnaires. For To and Tneutop, the average values obtained are 30.4 °C and 28.6 °C. Furthermore, the findings showed that only the morning session was in the acceptable operative temperature range and complied with ASHRAE Standard 55 for both the 80% and 90% acceptability limits. At the end of the study, it was found that the values from the thermal environment measurements and surveys exceeded those recommended by ASHRAE Standard 55. This concluded that the quality of the occupants’ environment in the cafeteria is outside the satisfactory thermal comfort level. Therefore, the improvement through mechanical ventilation may very helpful in improving a good ventilation system as well as encouraging an increase in thermal comfort in the building.

“…After the appearance of the Covid-19, these types of buildings gather even greater research interest, especially for the new conditions of ventilation that are formed due to the intense crowding that is observed (Gil-Baez et al, 2021;Di Gilio et al, 2021;Park et al, 2021). These new ventilation conditions can influence the IAQ, as well as the thermal comfort of the students (Miranda et al, 2022;Torriani et al, 2023). Measure of CO2 concentration is a good and cheap indicator for IAQ and ventilation (Rueda López et al, 2021).…”

During the pandemic of Covid-19, ventilation rate of buildings and especially in spaces with high occupancy like classrooms, presents high research interest. The ventilation strategies, combined with the use of masks, contribute to the decrease of the infection risk of Covid-19. Also, ventilation improves Indoor Air Quality (IAQ), contributing to the good health of the users and potentially influences their thermal comfort. In the proposed work, the experimental investigation of the ventilation’s adequacy in naturally ventilated classrooms located at the University of Western Macedonia, in Kozani, Greece, took place. Measurements include thermal comfort parameters, as well as IAQ ones, namely carbon dioxide (CO2), volatile organic compounds (VOCs), aldehydes and ozone (O3). The air exchange rates were determined according to the tracer gas decay and equilibrium analysis methods, using CO2 as tracer gas, while simulations analysis using appropriate computational approaches was applied. The results between tracer gas method and simulation analysis were compared, allowing the validation of the adopted models. Given that for both approaches natural ventilation proved to be inadequate, different simulated scenarios of ventilation, including natural and mechanical configuration, were investigated; the relation of ventilation rates to IAQ and thermal comfort was investigated. Moreover, the infection risk, given the determined or simulated IAQ, was assessed, according to relevant approaches.
