Block morphology refers to critical parameters influencing building energy performance on the block scale. However, analysis of the combined effect of block morphological parameters on building energy consumption with real blocks is lacking. In this paper, the aim is to evaluate the combined effect of office block morphology on building energy consumption in the context of the Hot-summer and Cold-winter zone in China. First, a workflow for the energy assessment of office buildings with the coupled block morphology on the block scale was proposed with evaluation tools. Seventy office blocks in Wuhan were taken as examples and then classified based on building layout typology and building height. Afterwards, the morphological parameters and building energy use intensity (EUI) for different blocks were calculated. Then, the combined effect of block morphology on the buildings’ energy consumption was evaluated and the model on predicting the building energy consumption of office blocks was proposed. Finally, based on the results, low-energy design strategies were projected for office blocks. The results illustrated that the effect of block morphology on building cooling, heating, and lighting is EUI 28.83%, 28.56%, and 23.23%, respectively. Building shape factor (BSF), floor area ratio (FAR), average building height of block (BH), and average building depth of block (BD) are effective block morphological parameters. The key morphological parameters which combined affect the building energy consumption of office blocks are BSF and FAR; BSF has 1.24 times the effect on building energy consumption than FAR. The workflow built in this paper can be applied to other cities around the world for promoting sustainable cities.

With the accelerated development of subways in China, elevated subway stations (ESSs) capitalize on natural ventilation and lighting to significantly save energy. Nevertheless, their thermal environments are rarely addressed. This study conducts annual thermal environment measurements, surveys, and thermal comfort analysis on five typical ESS buildings. The results of field measurements demonstrate that the station’s thermal environment is influenced by architectural space forms such as skylight ratio, platform doors, openness, and platform form. The standard effective temperature—predicted thermal sensation (SET*—PTS) equation was developed based on the survey, indicating that passengers’ thermal adaptability surpasses the PTS. In summer, the neutral temperatures for passengers in open and enclosed stations are 28.74 SET* °C and 27.13 SET* °C, correspondingly. In winter, they are 23.43 SET* °C and 21.98 SET* °C. Physiological changes that passengers experience during the transition from entering the metro station to arriving at the platform were measured and quantified, which confirmed differences in thermal adaptation during the shift between hot and cold environments, emphasizing thermal delay and accumulation effects. This study provides important guidance for the construction, renovation, and operation of ESS buildings and the development of related standards.
