Summary: Rising ambient temperatures due to climate change will impact indoor temperatures and heating and cooling utility costs. Tradeoffs in meeting heating and cooling demands and lack of AC access in colder climates require coordinated public policies. Our model results suggest that cooling subsidy policies can decrease indoor summer temperatures and increase energy consumption, with greater savings for retrofitted homes.

Summary: Growing evidence suggests that even a low CO2 concentration of 1000 ppm can pose direct health risks to humans, which is often exceeded in many indoor environments. To address this issue, we developed a CO2 purification module using a moisture swing sorbent and integrated it with existing air conditioning units. The sorbent can spontaneously bind and release CO2 from the air, depending on the moisture level, making it an ideal solution for indoor carbon capture. Tests in simulated indoor environments and an actual office demonstrated the effectiveness of the purification module in maintaining healthy CO2 levels. This decentralized carbon capture facility has the potential to contribute to negative emissions and mitigate the global warming and climate change crisis.

Summary: The study reevaluates past heat waves and finds that the Midwest is home to the most extreme heat waves. The extended heat index can assess the physiological stress induced by heat waves, and it is discovered that the most extreme Midwest heat waves have a severe impact on the cardiovascular system.

Summary: Earth-to-air heat exchanger (EAHE) technology shows promise for space heating/cooling but is usually not sufficient for indoor thermal comfort alone. Hybrid systems combining EAHE and an air-source heat pump (ASHP) can regulate indoor temperature and conserve energy. Full-scale experiments were conducted for a building in a typical hot-summer and cold-winter region in China, demonstrating the system's ability to cool and heat indoor air during summer and winter, respectively.

Summary: This study proposes an online modeling method for indoor temperature regulation based on building thermal process characteristics. By using a data-driven model and identifying parameters through multiple linear regression analysis, a model that retains system physical properties and can be updated online has been achieved. This model with building thermal process properties will be beneficial for the design of terminal controllers for indoor temperature regulation in air conditioning systems.

Summary: Indoor heat and air pollution are dangers to human health, especially for vulnerable individuals. This study examines the impact of summertime indoor overheating and airborne particulate matter (PM2.5) on low-income seniors and explores the potential benefits of natural ventilation in maintaining good indoor thermal conditions and air quality. The research findings highlight the trade-off between thermal comfort and air quality, and suggest the need for a comprehensive approach to improving comfort for vulnerable occupants.

Summary: This study proposed a modeling and prediction method for indoor temperature lag response characteristic based on time-delay neural network and Elman network neural, validated using variable air volume air conditioning system. Results showed that Elman network neural can be considered as a better modeling method with improved prediction accuracy and smaller storage space.

Summary: This study uses a Health Impact Assessment (HIA) model to estimate future heat-related mortality and air pollution cardiorespiratory mortality in Thessaloniki, Greece. The results indicate that population adaptation may reduce heat-related mortality, but this could be counterbalanced by higher air pollution-related mortality due to increased AC usage.

Summary: Based on field measurements and a questionnaire survey, the thermal environment and human thermal comfort of two typical subway stations in Xi'an were studied in summer. The relative warmth index (RWI) was used to analyze passengers' thermal comfort during the process of entering and leaving the station under operating and designed temperatures. The RWI method was modified based on comparative analysis and the suitable indoor air design temperature in Xi'an subway stations was discussed.

Summary: Global climate change has led to increased variability in air temperature and more extreme weather events. This study analyzed the relationship between daily air temperature and mortality in Shanghai in 2003, a particularly hot year. The results showed a V-shaped association between cause-specific mortality and daily air temperature, with different temperature thresholds for different age groups and mortality categories. Heat waves and cold spells in 2003 resulted in excess mortality, particularly among the elderly.

Summary: This study proposes an optimal control method to improve the control robustness of room temperature in a ground-source heat pump and air-conditioning system for villas. By calculating and adjusting the chilled-water return temperature, the control performance of indoor temperature is enhanced. The test results show good temperature control performance and reduced energy consumption.

Summary: This study examines the indoor environment of low-income housing during extreme heat events from the perspectives of energy and heat resilience. Passive cooling measures are proposed to improve heat resilience and energy efficiency, with findings indicating that current housing designs are not resilient to hot periods due to inefficiencies. Recommendations include promoting night ventilation and shading of the envelope to enhance heat resilience and reduce energy consumption.

Summary: Household air pollution from solid fuel combustion for cooking and heating is a major global health issue. A study in rural Ghana aimed to improve child health by providing clean cooking interventions during pregnancy, but found that neither LPG cookstoves nor improved biomass cookstoves led to improvements in birth weight or reduced severe pneumonia risk in the first 12 months of life. The researchers hypothesize that this lack of effect may be due to lower-than-expected reductions in air pollution exposure.

Summary: Approximately 3 to 4 billion people worldwide are exposed to household air pollution, which has been associated with increased blood pressure (BP) in pregnant women in some studies. This study recruited 3195 pregnant women in four countries and found that using gas stoves did not significantly affect gestational blood pressure.
