Summary: This study thoroughly examines several designs using the Trombe wall to improve the thermal comfort of occupants in buildings. It aids green building designers in making informed decisions based on the current environmental state and changing climate. Using locally accessible resources reduces the cost of importing substitute materials for these structures. With a focus on energy conservation, research is aimed at decreasing energy usage and maximizing alternative solar energy for thermal comfort. The Trombe wall is a cost-effective and eco-friendly approach for natural ventilation in summer but can cause overheating in winter.

Summary: This study compared the thermal comfort of two common heating terminals, BRH and FH, in urban residential buildings in cold areas of China. The results showed that FH terminals have significantly higher mean radiant temperature and operative temperature, leading to increased acceptance of low-temperature environment among occupants.

Summary: This study investigated the impact of pandemic restrictions on energy consumption, thermal comfort, and indoor air quality in mosques in Turkey. The results showed that lighting energy consumption decreased due to less usage during the pandemic, while heating and cooling costs increased in one mosque despite restricted usage. Keeping windows open and limiting occupancy improved indoor air quality, evidenced by lower CO2 concentration during the pandemic. The study also found that acceptable thermal comfort was achieved at night during the summer period under pandemic measures.

Summary: Localized heating systems, particularly local radiant heating systems, offer a solution for achieving thermal comfort with reduced energy consumption in cold environments. This paper reviews experimental studies on these systems, focusing on thermal sensation and comfort. The findings indicate that localized methods can enhance thermal comfort and achieve the same sensation at lower air temperatures, especially when using local radiant heating systems. To optimize the design of such systems, further improvement in modeling local thermal comfort and sensation based on radiant heat transfer is necessary.

Summary: Cold climates require mechanical heating, leading to increased energy consumption. Personalized local heating can save energy, but the thermal perception capabilities of different body parts remain unclear. This study found that using local heating devices with fixed surface temperatures significantly improved overall and local thermal perception and comfort in cool environments. Heating the waist had the strongest effect, improving overall thermal perception and comfort, while heating the knee and chest showed the least improvement.

Summary: This study investigates the effects of prior thermal history on human adaptability to centralized heating environments. The results indicate that individuals with no prior heating experience have a better initial perception of heat and higher acceptance and expectation levels in centrally heated environments.

Summary: This study examined the effect of non-uniform environments on thermal sensation under stratum ventilation for heating. The results showed that supply air temperature and velocity had different influences on the variation range of thermal sensations in different subzones. It was recommended to use a supply air temperature of 25-27 degrees Celsius and a velocity of no less than 1.1 m/s to improve thermal comfort.

Summary: Respiratory infections such as COVID-19 can spread through respiratory droplets larger than 5-10 micrometers or droplet nuclei smaller than 5 micrometers. In enclosed spaces, frequent ventilation is recommended, along with wearing masks, to prevent infections. Displacement ventilation systems may offer a feasible and secure option for controlling disease transmission in temporary hospitals and other buildings.

Summary: A modified impinging jet ventilation system is proposed and numerically evaluated in a densely occupied classroom mockup. The results show that the system improves indoor air quality significantly, reduces infection probability, and decreases cooling coil load, although thermal comfort level and uniformity are slightly compromised.

Summary: The purpose of this study was to assess pedestrians' thermal perception in the semi-arid climate of Constantine, Algeria, with a focus on the protocols implemented in public spaces during the post-COVID-19 period. The findings revealed a strong association between microclimate parameters and pedestrians' thermal sensation, as well as the significant influence of subjective variables such as thermal history and purpose of visit. Most respondents preferred seeking shade as a remedial behavior to reduce thermal discomfort. The study also determined the comfort range and analyzed the impact of COVID-19 measures on pedestrian activities and thermal discomfort.
