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.

Summary: This study proposes a novel Adaptive Comfort for Low-Income Housing (ACL) model for the low-income housing of Mumbai, India. The study found that low-income occupants have lower thermal sensitivity and a wider comfort temperature band compared to their affluent counterparts. The existing national and international comfort standards are ineffective in predicting comfort conditions for Indian low-income occupants.

Summary: This study examined how children adapt to the thermal conditions in classrooms without air conditioning in Dehradun City, India. The results showed that most of the classrooms did not meet the students' comfort requirements. Children had low sensitivity to temperature variations, but were still satisfied with the thermal conditions even in extreme heat risk situations. Adjusting clothing, opening windows and doors, and using ceiling fans were found to be the most affordable ways to optimize indoor thermal comfort.

Summary: The adaptive thermal heat balance (ATHB) framework introduces a method to account for physiological, behavioral, and psychological adaptation individually within existing heat balance models. This study presents a more detailed theoretical framework and a new formulation of the ATHB(PMV) based on theory-driven empirical determination. Through an empirical development using a subset of the ASHRAE Global Thermal Comfort Database, the results show improved predictive performance in various outdoor climates, building types, and cooling strategies. The framework challenges the common belief that psychological adaptation is highest in naturally ventilated buildings and provides opportunities to include context-related variables and personal characteristics in thermal prediction models.

Summary: This paper evaluates the thermal comfort of vernacular dwellings in Alentejo, Portugal, and finds that these dwellings have high thermal acceptability in summer but lack sufficient heating in winter. The study also finds that the PTC model accurately represents summer thermal comfort conditions in vernacular dwellings. The current comfort evaluation methods are deemed unfit for vernacular dwellings.

Summary: Future-oriented urban planning should continue to focus on the principles of accessible and walkable cities. The perception of people is crucial for developing better urban walking infrastructure, but current evaluation tools often neglect the "perceived" features of the walking network. This study used conjoint analysis to evaluate users' perception of link and network attributes, revealing the importance of considering both in improving the walking environment.

Summary: This paper comprehensively analyzes the energy consumption characteristics of electric buses (EBs) and diesel buses (DBs) on different bus lane configurations and operational conditions. The study shows that EBs consume less energy in suburban areas when using regular lanes, while both EBs and DBs save substantial energy when operating on dedicated bus lanes in downtown areas. Notably, shared-use bus lanes have the highest energy consumption.

Summary: This study examines the impact of land cover, vegetation health, climatic forcings, elevation heat loads, and terrain characteristics on land surface temperature distribution over West Africa. The random forest model performs the best in downscaling predictands. The southern regions consistently exhibit healthy vegetation, while areas with unhealthy vegetation coincide with hot land surface temperature clusters. Positive Normalized Difference Vegetation Index trends in the Sahel highlight rainfall recovery and subsequent greening. Southwest winds cause the upwelling of cold waters, resulting in low land surface temperatures in southern West Africa. Considering LVCET factors is crucial for prioritizing greening initiatives and urban planning.

Summary: This study analyzes the structure, function, operation, and failure characteristics of district heating networks (DHNs) and proposes vulnerability analysis methods. The effectiveness of these methods is validated through application to a DHN in a Chinese city. The study finds that the heat source connectivity efficiency loss rate effectively characterizes topological and functional vulnerability. It also reveals that controllable DHNs have higher functional vulnerability under large area failure scenarios.
