Indoor environmental quality (IEQ) significantly impacts human health, well-being, and productivity. However, a comprehensive in-depth review of the combined effects IAQ other multi-domain factors on productivity is lacking. There has not been any prior that encapsulates impact physiological responses occupants. To address this gap, paper investigates highlights (thermal, visual, acoustic) occupant well-being in built environment. The explores various research methods, including evaluation creativity, data collection, signal analysis. We also examined interactions between factors, as well strategies for optimizing through integrated building design smart systems. key findings from reveal with IEQ further impacting these effects. Despite advances field, there are several limitations gaps current methods study designs, small sample sizes, limited insufficient experimental control, reliance laboratory or simulated environments, lack follow-up long-term data, robust performance metrics. proposes future directions, specific applications, work to advance understanding implications policy practice include need holistic approaches management, focus creating healthy productive indoor environments. This emphasizes importance considering complex interplay potentials adopting control systems sustainable optimize By addressing critical issues, we can enhance overall life occupants contribute more future.

Critical indoor environmental factors affecting productivity: perspectives from university staff and postgraduate students

Building Research & Information, Год журнала: 2023, Номер 51(6), С. 730 - 745

Опубликована: Май 1, 2023

Indoor environmental quality (IEQ) of buildings plays an important role in affecting building occupants' comfort, health and well-being. However, there is limited understanding the critical IEQ factors that affect work productivity university office buildings. By surveying 204 people (72 staff members 132 postgraduate students) a tertiary education institution New Zealand, this research aimed to identify rank concerning their perceived how importance these differed between student cohorts. Statistical analysis identified total 16 as productivity, 15 them, except cleanliness office, could be grouped into four categories: (1) thermal comfort lighting; (2) acoustics privacy comfort; (3) spatial (4) aesthetics views. Based on factors, framework was developed can used by facility managers designers sector optimize design solutions improve performance more conducive occupants. The findings from inform inclusion features will enable students using achieve better productivity.

Influence and prediction mechanisms for discomfort and memory disturbance due to structure borne sound from metro masked with fountain sound

Acta Acustica, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Previous studies suggested that introducing fountain sound could mitigate the discomfort and memory disturbance caused by structure borne from a metro, proposed prediction models for after mitigation. However, these failed to identify influence degree of factors on mitigation, which hindered proposal optimal masking strategy undermined scientific validity models. Additionally, previous analyses did not address mitigation or provide it. Therefore, this study explored aspects further. Based auditory experiments, using partial least squares model model, found considering total impact degree, was predominantly influenced subjective loudness. levels were most important in determining The signal-to-noise ratio significantly but had no significant disturbance. loudness emerged as effective predictor discomfort. While predicting depended more levels, among based predictive effectiveness energy summation comparable independent effects model. As global equivalent A-weighted level increased, effect became evident, its mitigating gradually decreased. These conclusions strategies enhancing such effects, tools effects.

Flame and Smoke Semantic Dataset: Indoor Fire Detection with Deep Semantic Segmentation Model

Electronics, Год журнала: 2023, Номер 12(18), С. 3778 - 3778

Опубликована: Сен. 7, 2023

Indoor fires can easily cause property damage and especially serious casualties. Early timely fire detection helps firefighters make scientific judgments on the of fires, thereby effectively controlling accidents. However, most existing computer-vision-based methods are only able to detect a single case flame or smoke. In this paper, tailored deep-learning-based scheme is designed simultaneously smoke objects in indoor scenes. We adopt semantic segmentation architecture DeepLabv3+ as main model, which an encoder-decoder for both objects. Within this, key module, e.g., atrous convolution, integrated into improve image resolution accurately locate targets. addition, solve question insufficient dataset, we prepare construct new annotated dataset named ‘Flame Smoke Semantic Dataset (FSSD)’, includes extensive information collected from real scenes other sources. Experiments conducted our FSSD database comparisons with state-of-the-art (FCN, PSPNet, DeepLabv3), confirm high performance proposed 91.53% aAcc, 89.67% mAcc, 0.8018 mIoU, respectively.

Exploring office comfort and productivity in living labs: A yearlong structural equation modeling study

Building and Environment, Год журнала: 2023, Номер 250, С. 111147 - 111147

Опубликована: Дек. 25, 2023

The relationship between workers' environmental comfort and productivity has been extensively studied over the years, yet real-world investigations remain limited. Living labs provide an opportunity to observe interactions different domains their impact on occupants. This study aims investigate connection contextual factors, visual thermal sensations, comfort, how they relate self-perceived of office workers in a Lab setting, utilizing Structural Equation Modelling (SEM). Comfort sensation perception surveys were conducted during each session year, alongside sensing system continuously monitoring temperature, illuminance, window/door operations five offices participating study. Subjects working single reported higher than those shared across all conditions. Contextual characteristics, such as time day, had significant defining satisfaction. A cross-modal effect was observed domains, highlighting that evaluating factors isolation from assessment overlooks critical elements building physics. These findings underscore importance considering broader context when assessing people's surroundings operational changes spaces can enhance employees' judgment.

This research examined the modeling of productivity with thermal comfort using various models in a case study conducted classrooms at university Southern Brazil. A total thirteen were selected after performing literature review to identify main models. Through application hierarchical clustering separate into groups similarities, results identified four groupings: first focused on temperature, second associated age Thermal Sensation Vote (TSV), third compared different groups, and fourth highlighted “Model 11”, derived from structural equations air-conditioned China, revealing poor performance due its incompatibility temperature variations productivity. Meanwhile, 5”, developed ordinary regression offices Japan, showed lowest Root Mean Square Error (RMSE), emerging as most accurate predicting comfort. The use objective methods assess analysis modeling, review, is noteworthy. evaluation models’ also explored impact independent variables their scope. cluster analysis, reasons behind discrepancies model identified, providing insights best practices for representing relationship between These offer valuable perspectives developing more effective this field reveal wide methodological diversity approach subject.
