Summary: The thermal environment quality in office buildings plays a crucial role in human productivity, and comfort standards are necessary to create a comfortable indoor environment. Outdoor climatic conditions have a greater impact on thermal conditions in naturally ventilated buildings compared to air-conditioned ones. The study proposes an adaptive comfort equation for both types of office buildings and emphasizes the need for climate-specific standards to achieve energy-efficient design.

Summary: Personal thermal management (PTM) technologies, which establish a local thermal envelope around the human body, have great potential for reducing building energy use and improving thermal comfort. Traditional PTM technologies include off-body and on-body devices, while recent advancements in nanotechnologies and materials have led to exploration of novel fibers and textiles. While PTM technologies currently have the potential for significant energy savings in buildings, further research is needed to evaluate thermal comfort for wearable textiles and develop additional performance indices.

Summary: In this study, a hybrid phase change material was prepared by mixing microencapsulated phase change material and composite phase change material. Two types of gypsum-based PCM wallboards were then prepared and evaluated. The results showed that the hybrid wallboards exhibited good thermal performance and energy efficiency in different seasons. Overall, the hybrid wallboards are more suitable for practical application in building energy saving.

Summary: Phase change materials (PCMs) have the potential to improve building thermal comfort and save energy in energy-efficient buildings. This study evaluates the passive use of PCM in a thin building envelope in a severely hot location using EnergyPlus software. The results show that PCM effectively reduces temperature fluctuations, levels thermal load, and reduces operative temperature. The integration of PCM also leads to significant energy-saving and environmental benefits, including CO2 emission reduction and electricity cost savings.

Summary: This study aimed to investigate the thermal comfort requirements in residential buildings and establish an adaptive thermal comfort model. A two-year field study was conducted on residential buildings in Shaoxing, Zhejiang Province, China. The results showed that the thermal comfort requirements of residents change with the seasons and seasonal models reflect the residents' thermal adaptation caused by dynamic climate change more comprehensively and accurately. In addition, this study determined the residents' psychological and behavioural adaptability to the seasons and found the characteristics of thermal sensation and requirements for thermal comfort in different seasons. The results could be used as a basis to improve energy efficiency and meet comfort needs in the future.
