Summary: The research proposed an adaptive thermal discomfort evaluation model called Air-conditioner based Adaptive Predicted Percentage of Dissatisfied (aaPPD). By collecting indoor and outdoor temperature and humidity data, extracting resident air-conditioner-turning-on behaviors, and building a nonlinear model, the research simplified variables for easy calculation parameters, aiming to adapt better to the early architectural design stage.

Summary: This study proposes a data-driven approach based on the Chinese Thermal Comfort Database to determine indoor air temperature ranges that are thermally acceptable to 80% of occupants under different conditions. The results show that different regions, seasons, and building types have varying acceptable temperature ranges, with an average of 2.0 degrees C wider than ISO 7730 and 0.7 degrees C wider than GB50736-2012 standards. The new model has higher accuracy in predicting thermal acceptability percentages compared to traditional methods.

Summary: The study found that in high-density central areas of Harbin, air temperature and environmental temperature have a significant impact on outdoor thermal comfort, with preferred temperatures of 24.8 degrees Celsius in summer and 23.5 degrees Celsius in the transition season. Residents in severe cold areas have psychologically adapted to the cold environment and are less sensitive to low temperatures due to long-term exposure.

Summary: Previous studies have shown that window-windcatchers effectively capture and redirect wind into a building, increasing ventilation ratio by 9%. However, the impact of this system on energy performance, costs, and thermal comfort has not been studied. In this research, the implementation of a window-windcatcher on a residential building was investigated using a validated DesignBuilder model. Results showed a 23.3% reduction in annual energy consumption and cost, as well as a decrease of 290 thermal discomfort hours per year.

Summary: Occupant basic clothing insulation is crucial for calculating thermal comfort indices and HVAC sizing processes. However, inaccurate estimations of clothing behavior can lead to poorly designed indoor environments and unnecessary energy consumption. This study develops a convolutional neural network based on a large universal dataset, which accurately predicts occupant basic clothing insulation and outperforms conventional deep learning architectures.

Summary: Most thermal comfort research has focused on office and commercial buildings, neglecting the importance of educational facilities. This study investigates thermal comfort settings in secondary school classrooms in Abuja's hot and dry climate and finds that none of the studied classrooms met the ASHRAE Standard-55 comfort range. However, 44% of students still felt comfortable, indicating a need for a local thermal comfort standard.

Summary: In multi-zone buildings, a shared thermostat is often used to control multiple conditioned zones. This study aims to evaluate the impact of different sensor locations for multi-zone commercial buildings in terms of energy consumption and thermal comfort. Two scenarios were compared, one using selected sensor readings for no-sensor zones and the other using average temperature from shared zones for each shared zone.

Summary: This study aims to investigate the filter performance of different outlier detection methods. Results show that all three rules can filter some obvious outliers, and the Boxplot rule produces the most moderate filer results, whereas the 3-Sigma rule sometimes fails to detect outliers and the Hampel rule may provide an aggressive solution that causes a false alarm.

Summary: This study compared the feedback collected through CSOF systems with manually conducted surveys, finding a small Mean Absolute Error for both Occupant satisfaction and complaint feedback. Logistic regression techniques were used to investigate the relationship between feedback and survey data, showing that cumulative link models were suitable for modeling the data. Further studies utilizing a larger dataset are recommended to deepen the understanding of CSOF feedback significance.

Summary: The movement behavior of office workers is influenced by spatial and environmental attributes. Increased visibility of colleagues is associated with reduced movement, while the distance to office destinations is positively associated with the duration of movement. Associations with IEQ exposures are primarily related to stationary behaviors. These findings suggest potential avenues for design and policy-based interventions to reduce stationary time and increase movement in the workplace.

Summary: This study examines the perception of thermal comfort and behavioral adaptation of residents in Sydney and Brisbane, Australia. The statistical analysis reveals that the current international standard of adaptive comfort model may not be suitable for residential buildings, and suggests expanding the acceptable temperature range to around 11 K. The findings also demonstrate that the climate influences the shifting of the 80% acceptability range.

Summary: Thermal comfort research aims to study the relationship between thermal environment and human sense of warmth, usually through subjective thermal response. However, using linear regression to analyze ordinal data may result in severe errors. This study establishes methodological foundations for analyzing subjective thermal comfort data and demonstrates the practical consequences of fallacious assumptions through a Bayesian approach. The findings highlight the importance of using ordinal models instead of metric models for analyzing ordinal data.

Summary: Thermal experiences in outdoor and semi-outdoor environments have a significant impact on people's overall nature experience and restorative benefits. This research compares the differences in thermal pleasure, adaptive behaviours, and restorative benefits between Chinese and Australian cultural groups in identical semi-outdoor environments. The study found that Chinese participants generally felt thermally unpleasant and engaged in sunlight avoidance behaviours, while Australian participants felt thermally pleasant and engaged in sunlight maximising behaviours. Access to shade as an adaptive opportunity can potentially reduce cultural differences in thermal pleasure and restorative benefits resulting from outdoor exposures.

Summary: The study compared the ambient temperature thresholds for warm thermal discomfort, thermal unacceptability, and preference for cooler environment between post- and pre-menopausal women at different metabolic rates. The results showed that while a higher metabolic rate led to a lower air temperature threshold for warm thermal discomfort, there was no difference in this threshold between pre-menopausal and post-menopausal women, regardless of metabolic rate. However, post-menopausal women reported an environment to be unacceptably warm and expressed a preference for a cooler temperature at a lower ambient and forehead skin temperature.

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.
