Given that the construction industry accounts for 38% of worldwide carbon emissions, targeting sustainability in this sector is vital. Due to the multi-dimensional nature of the tall building design process, optimization shows growing promise in developing solutions that increase design efficiency while sufficiently exploring design spaces and limiting computational costs. However, integrating architectural concepts with structural design to ensure that aesthetic goals are met without compromising structural integrity is challenging. Additionally, the critical dependency of lateral load magnitudes on a building’s outer shape and structural details underscores the need for a holistic design approach to meet both serviceability and capacity requirements for highly tall and flexible structures. Characterized as dynamically sensitive structures, tall buildings require thorough consideration of wind and seismic loads, which exert a dominant influence on the structural system. This paper provides a roadmap for the structural optimization of tall buildings, focusing on wind loads, presenting a perspective on design parameters, algorithms, and modelling techniques, in addition to utilizing machine learning in various design stages. It also assesses the impact of different load types on the optimization process, the role of surrogate models in facilitating design frameworks, and innovative methods offering promising solutions surpassing current capabilities.

However, how such indoor overheating environments affect the human body over time remains insufficiently understood, and comprehensive evaluation methods are still lacking. This study explores the thermal effects of indoor overheating through a three-zone framework representing thermal comfort, thermal health, and thermal safety. A climate chamber experiment was conducted under typical overheating conditions in hot and humid regions. Objective measurements and subjective questionnaires were combined to track psychological responses, adverse symptoms and physiological parameters over the exposure period. Based on the experimental results, a three-zone system was proposed, comprising the “Unacceptable Without Symptoms Zone” (TUAZ), “Unacceptable With Symptoms Zone” (SZ), and “Multiple Symptoms With Danger Zone” (TDZ), representing progressively increasing thermal stress on the human body. The findings revealed that thermal acceptability declined rapidly in overheating environments, with symptoms such as drowsiness, fatigue, restlessness, and chest tightness emerging over time, and that prolonged exposure increased life-threatening risks. At a heat index (<em>HI</em>) of 47 °C, the time thresholds for TUAZ, SZ, and TDZ are 0 min, 30 min and 120 min, respectively. Skin temperature serves as a key physiological indicator, with thresholds of 34.6 °C and 35.8 °C for zoning TUAZ and SZ.

This study reveals and justifies the mechanism for advancing air distribution, <em>i.e.</em>, the air potential should be maximally used, which indicates the air potential is used cascadingly to match the zonal priorities. Regarding thermal comfort, the supply air should be used sequentially to condition the breathing, lower, and upper zones, which is described quantitatively by the Matching of Thermal Potential, a newly proposed index. The larger the Matching of Thermal Potential, the higher the energy efficiency. This is verified by the coefficient of determination (<em>R</em><sup>2</sup>) of greater than 0.95 for the case studies on mixing ventilation, displacement ventilation, stratum ventilation, and interactive cascade ventilation. Moreover, due to the coupled heat and mass transfer, a higher Matching of Thermal Potential leads to a younger mean age of air in the breathing zone.

It reduces energy consumption by 8.4% - 53.5% and the mean age of air in the breathing zone by 7.8% - 23.4% under different thermal conditions.

This decentralisation entails complex spatiotemporal flows, both of energy itself through infrastructure, and of real-time information to balance energy supply and demand. We address ten questions about the governance of decentralised energy systems, to identify the quandaries that regulators and operators must resolve for mainstreaming decentralisation as a strategy towards low-carbon energy systems. Crucially, this implies understanding energy flexibility as a relevant concern down to building and block scale, and developing and deploying transition metrics for cross-sectoral coordination to enable sustainable energy use in decentralised systems.

However, the amount of energy required to create optimum cultivation conditions can lead to high operating costs (especially in Europe) and other environmental impacts. In this study, we discuss those issues in relation to the construction, operation and management of an urban vertical farm, via life cycle analyses. The study is conducted with SimaPro, considering scenarios that combine the supply of building materials, building design life and transportation distance of the products, while exploring ways to reduce carbon emissions through wind energy harvesting. The results obtained indicate that the investigated urban vertical farm yields a GWP of 5.43 kg CO<sub>2</sub> eq per kilogram of lettuce under the current grid structure, which is 9–14 times higher than that of traditional open field farming. However, the main reason for the exponential increase in GWP is the power consumption of artificial lighting and HVAC systems. Among these, 3.61 % of life-cycle carbon emissions can be saved by recycling waste lettuce at the use and production phase.

This study investigated the impact of incorporating fractal patterns with varying fractal dimensions into interior environments on occupants’ physiological stress. Using immersive virtual environments, fractals with three levels of fractal dimension were implemented as wall finishes in full-scale interior simulations. Participants’ skin conductance levels and heart rates were measured as they experienced mild stressors and subsequently recovered in these environments. Results indicated that exposure to mid-range fractals (FD = 1.3–1.5) had a positive influence on heart rate during recovery, suggesting their potential to support stress reduction. Additionally, a significant difference in skin conductance increase was observed among groups, with the lowest increase recorded in the low-FD (1.2) condition.

Therefore, it is important to investigate dust dispersion within realistic urban building layouts. In this field Discrete Phase Model (DPM), widely used in Computational Fluid Dynamics (CFD), has limited applicability in large-scale studies due to its high computational cost. Alternatively, the Species Transport Model (STM) offers a more efficient approach but suffers from unclear dust emission, often compromising accuracy.

Findings reveal that high dust concentrations tend to accumulate in low-wind-speed zones dominated by vortex effects. Furthermore, the effects of varying wind speeds and directions on dust dispersion were systematically analysed. The results indicate that high wind velocities cause dust accumulation on the windward side. Based on fractal dimension analysis, an evaluation framework for dust distribution was established. The findings demonstrate that the complexity of dust dispersion boundaries is governed by wind direction and that more irregular transport boundaries lead to a broader spatial extent of dust distribution.
