A hybrid active learning framework for personal thermal comfort models

Zeynep Duygu Tekler et al.

Summary: In this study, a hybrid active learning framework was proposed to reduce data collection costs for developing efficient and robust personal comfort models. Two active learning algorithms and two labelling strategies were evaluated to achieve optimal reduction in user labelling effort. The results showed significant reduction in labelling effort for thermal comfort and air movement preference models, with increasing reductions over time and with new users. This study highlights the potential of active learning as an effective solution for the high cost of data collection in data-driven thermal comfort modelling.

Experimental assessment of thermal and acoustics interactions on occupant comfort in mixed-mode buildings

Yuzhen Peng et al.

Summary: Mixed-mode buildings utilize both natural ventilation and mechanical air-conditioning systems to achieve energy savings without compromising occupant comfort. However, there is a lack of clear guidelines for assessing occupants' thermal perception and the interaction effects between thermal and acoustic comfort in these buildings. This study conducted a field study in a mixed-mode office building in Singapore and found that the operation modes and traffic noise significantly affect thermal sensation and acceptability. The findings suggest the need for a different thermal comfort model and provide valuable information for the practical operation of mixed-mode buildings.

Effect of elevated air temperature and air velocity on thermal comfort and cognitive performance in the tropics

Chao Cen et al.

Summary: Long-term experiments were conducted in tropical Singapore to investigate the thermal comfort and cognitive performance of participants in fan-assisted cooling environments. The results showed that elevated air velocities can maintain thermal comfort at air temperatures ranging from 27 to 30 degrees C. Participants' mean skin temperature increased with air temperature and decreased with air velocity. Cognitive performance was influenced by the sensation of warmth, with lower performance scores compared to cool and neutral sensations. However, there were no negative effects observed in the cognitive performance with cooler sensations. Overall, cognitive performance was not affected by elevated air temperature and air velocity when thermal comfort was maintained.

Transient transmission of droplets and aerosols in a ventilation system with ceiling fans

Wenxin Li et al.

Summary: Ceiling fans have been found to effectively reduce the transmission of droplets and aerosols during coughing by diluting the concentration of particles in the air. They can change the airflow pattern and provide better protection against cough exposure.

Energy savings and thermal comfort in a zero energy office building with fans in Singapore

Michael G. Kent et al.

Summary: Fan-induced air movement can reduce the energy requirements of air-conditioning by allowing temperature setpoints to be raised without compromising thermal comfort. In a study conducted in a Zero Energy office building in Singapore, the installation of ceiling and desk fans led to a 32% reduction in energy consumption and a significant decrease in overcooling. There were no negative impacts on thermal satisfaction or subjective measures of air freshness, alertness, and concentration, indicating that fans can improve thermal comfort without drawbacks.

A practical deep reinforcement learning framework for multivariate occupant-centric control in buildings

Yue Lei et al.

Summary: This study proposes a practical deep reinforcement learning framework for occupant-centric control of HVAC systems, which considers personalized thermal comfort and occupant presence. The framework achieves multi-dimensional control of the HVAC system in a real environment and shows significant energy savings and improvements in comfort.

A review on buildings energy information: Trends, end-uses, fuels and drivers

M. Gonzalez-Torres et al.

Summary: Buildings contribute significantly to climate change, but there is a lack of reliable and consistent data for the development and evaluation of mitigation policies. Residential buildings have the highest energy consumption, with HVAC systems being the main source. Electrification has the potential to mitigate climate change if renewable power is promoted, but global cooperation is needed to break the link between economic growth, urbanization, and energy consumption in developing nations.

Occupant satisfaction with the indoor environment in seven commercial buildings in Singapore

Toby Cheung et al.

Summary: Understanding occupants' satisfaction with IEQ is crucial in improving indoor environmental quality. The study in Singaporean commercial buildings revealed high satisfaction with flexibility, lighting, and cleanliness, but dissatisfaction with sound privacy, personal control, and temperature. Major contributors to thermal dissatisfaction were identified as insufficient air movement and overcooled workspaces, while occupants in open plan offices were unhappy with noise from nearby colleagues. Additionally, several IEQ variables were not individually significant to overall workspace satisfaction, but their impact was substantial when merged into larger environmental factors.

Human thermal comfort under dynamic conditions: An experimental study

Matteo Favero et al.

Summary: This exploratory study on human response to thermal variations identified two mechanisms causing discomfort events due to overheating and undercooling, and revealed that current standard recommendations underestimate the risk of thermal discomfort during a cooling process. The findings can lead to more energy-efficient and satisfactory building control strategies.

Dynamic thermal pleasure in outdoor environments - temporal alliesthesia

Sijie Liu et al.

Summary: This study investigated thermal pleasure dynamics in outdoor environments based on the concept of thermal alliesthesia, and found that predicting temporal pleasure change could be achieved using thermal sensation change. Different prediction models were proposed for subjects in strong alliesthesial potential zones and those in thermoneutral zones, contributing to a more nuanced interpretation of outdoor urban spaces in terms of thermal pleasure and delight.
