“…In temperate climates, buildings have always been shaped as elongated South-facing blocks, which guaranteed maximum and minimum gains in winter and summer, respectively ( Figure 1). Modern studies [30,31] confirmed that an East/West elongation is an optimal compromise; in particular, those who focused on Compactness [32] or South Shape Factor [33] have observed that the energy use increases with the East and West façade areas. Ourghi et al [34] found further correlations amongst glazing type, glazing area, and energy use.…”

Over the decades, a rapidly changing climate has prompted the world’s most influential leaders and institutions to take action against such an imminent threat. The introduction of Nearly Zero Energy Building (nZEB) concept, though, has barely triggered a major shift, while voluntary labelling systems do not seem to offer any reasonable alternative. Building design ought to be readdressed from the ground up, with climate-responsive constructions servings as a valuable starting point for the purpose. In this paper, conventional bioclimatic design is enhanced and supported by the introduction of Building Automation Control Systems: Typically, the former determines long-term seasonal patterns, whereas the latter only affects the short-term behavior. Their schedules are based on realistic assumptions, while set-points are fine-tuned following energy simulations. Good results have been achieved for a case-study facility in Porto, both in terms of indoor adaptive thermal comfort (the simulated operative temperature complies the adaptive comfort model for more than 98% of the reference year) and energy use (reduced by 53%, compared to a baseline building, devoid of any automation system). Being focused on the decision-making rather than on specific items of design, the authors claim that such an approach may be employed in any climate, regardless of the building type or size, as long as the process is driven by a genuine analysis of the local context (i.e., climate) and by purposefully devised energy simulations.

“…The study showed that prismatic formed buildings gain lower solar than orthogonal forms and so consume less energy by an average of 7.88%. Moreover, Caruso et al [24] used the mathematical theory of calculus of variation to find the best geometric form to minimize direct solar irradiation incident on the envelope. The paper also aimed at finding useful guidelines and rules for designers to follow during early decision-making stages to reduce the total amount of direct solar irradiation [24].…”

Incorporating passive cooling devices within building design requires analysis of device variables and actions to improve cooling performance, maximize efficiency, and integrate with building elements. Improving devices performance requires understanding the relation of devices to design stages, building elements, and working mechanism, and actions performed by devices to enhance cooling process and effectiveness. Therefore, designers could integrate passive devices as intrinsic design elements. The current research introduces SARS as an innovative classification of passive devices based on cooling actions that are performed by a device like storing, avoidance, removal or slowing (SARS). All actions, devices, and variables were discussed and analyzed to help integrate them within design stages: analysis, designing, and performance. Understanding actions will help maximize the performance of the devices, combine two or more devices together, and integrate the devices' deign in design process. Combining more devices together to perform more than one function will move passive design to a new level to become as whole building design approach and to be a core design element.

“…Koichi conducted on-the-spot measurement to Granadeiro et al used parameterized language on the Matlab platform to generate a series of building forms and obtained through analysis the annual energy consumption levels of different building forms in connection with EnergyPlus simulation [40]. At the stage of conceptual design, Caruso et al optimized building forms with the aim of minimizing the receipt of solar radiation by using the calculus of variations of mathematical theory [41]. Xu et al estimated the impact of open space on the urban micro-climate and validated the open space design strategies through performance-based optimization, however, which need further consideration of the impact of building form, street orientation, and so on [3].…”

In areas with a dry and hot climate, factors such as strong solar radiation, high temperature, low humidity, dazzling light, and dust storms can tremendously reduce people’s thermal comfort. Therefore, researchers are paying more attention to outdoor thermal comfort in urban environments as part of urban design. This study proposed an automatic workflow to optimize urban spatial forms with the aim of improvement of outdoor thermal comfort conditions, characterized by the universal thermal climate index (UTCI). A city with a dry and hot climate—Kashgar, China—is further selected as an actual case study of an urban block and Rhino & Grasshopper is the platform used to conduct simulation and optimization process with the genetic algorithm. Results showed that in summer, the proposed method can reduce the averaged UTCI from 31.17 to 27.43 °C, a decrease of about 3.74 °C, and reduce mean radiation temperature (MRT) from 43.94 to 41.29 °C, a decrease of about 2.65 °C.
