Summary: This study developed a potential index for natural ventilation based on indoor and outdoor environmental factors, and found that the actual window opening time was significantly lower than the potential availability. The results indicated that the behavior of keeping windows open or closed was the key limiting factor in utilizing the potential of natural ventilation.

Summary: Climate change will increase cooling demands in buildings, affecting the efficacy of passive solutions. Building energy simulations often overlook the changing climate. In this study, updated weather files were used to reassess the impact of climate change on a hybridized heat pump system and the results showed increased cooling loads and heat build-up in the ground. However, the GSHP-NV-PCS approach remained a resilient solution with significant energy reduction potential.

Summary: This study discusses the assessment of NVP under two approaches: a general evaluation using only meteorological data, and a specific investigation through building simulation. The research found differences in the frequency of wind direction/speed values in climatic data, but similarities in the hourly data. A multi-zone Airflow Network model was employed for specific NVP examinations.

Summary: Combating climate change requires reducing energy use and improving energy efficiency. This study examines the impact of different heating and cooling scenarios on warmer future weather and finds that cooling demand increases significantly due to climate change. Mitigating measures, such as reducing internal heat loads, can decrease cooling demand and energy consumption.

Summary: This study aimed to determine the effect of using evaporative air coolers indoors in the tropical climate of Thailand on thermal comfort, with results showing a lower thermal comfort level achieved by evaporative air coolers and potential discomfort from overly damp air. Air temperature and velocity were identified as the two most influential variables affecting thermal sensation in the application of evaporative air cooling.

Summary: Occupant behavior (OB) is a significant factor contributing to the energy performance gap in buildings. Previous studies have developed OB models in residential and office contexts, but there is a knowledge gap in naturally ventilated and mixed-mode school buildings. This study addresses this gap and identifies research gaps and future topics, including investigating teachers' behavior and the impact of the COVID-19 pandemic on OB in school buildings.

Summary: Recent studies have shown that window opening behavior is influenced by environmental and contextual factors as well as daily habits, but little research has focused on habitual window opening behavior in residential buildings. A study conducted with Belgian households revealed that almost all occupants have window use habits, with household and building characteristics playing a small role compared to habits from other rooms. A window use habit model has been created based on these insights, showing promise in linking window use to everyday life for predicting realistic and justifiable window use.

Summary: This study proposes the use of personal comfort systems (PCS) and natural ventilation (NV) to reduce the thermal load imbalance in a cooling-dominated building. Building energy simulations show that hybridization with NV or PCS can increase the energy efficiency of the GSHP system, but only the combination of both NV and PCS can fully meet the thermal load.

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: 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: This research explores the perception of teachers on indoor environmental quality (IEQ) in relation to actual monitored data. The findings indicate that teachers' perception of ventilation is not accurate, and those in classrooms with poorer ventilation were more satisfied with IEQ. Errors in HVAC system installation and programming contributed to misunderstandings. CO2 monitoring and teacher education are crucial for creating a safe classroom environment.

Summary: Kunming has a unique climate and most residential buildings are naturally ventilated. Despite the indoor temperature being lower than the comfort range, most residents still feel neutral and comfortable. The neutral temperature in Kunming is determined to be 16.96 degrees C, with an acceptable thermal sensation vote (TSV) range of -0.72 to 1.52.

Summary: The expected energy use of buildings often differs from actual observations, a phenomenon known as the energy performance gap. While various factors can contribute to this gap, there is ongoing debate about the extent to which occupants play a significant role. Current evidence does not sufficiently support the claim that occupants are the main cause of the energy performance gap.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.

Summary: The continuous growth of global electricity penetration has provided modern energy for alleviating energy poverty, but its impact on carbon neutrality has been overlooked. The research reveals that clean electricity from traditional fossil energy and renewable energy has a positive influence on the greenhouse effect. Eradicating energy poverty can effectively alleviate the greenhouse effect, especially in non-Belt and Road Initiative (B&RI) nations.
