“…The butterfly is now widely used in architectural design and research. Scholars such as Kabosova and Chronis blended the newly developed AI-driven simulation prediction models of InFraReD, ladybug and butterfly with the Galapagos optimization within Grasshopper to investigate the relationship between architectural intention and weather influences to get the optimal design solution for the urban configuration and architectural shape [26,27]. Kamel studied the relationship between urban microclimate, building energy usage, and thermal comfort outdoors of two regions of Egypt by using Ladybug, Honeybee and Butterfly plugins across Grasshopper [28].…”

In the post-epidemic era, there is a growing demand for health-oriented spaces. In moderate climate regions (where the outdoors is warmer in the summer and cooler in the winter, neither to an extreme), external spaces offer a greater potential to create healthy and comfortable environment compared to internal spaces, with extended utilization periods. Transition spaces, a distinctive type of external space, are prevalent in numerous campus architectural designs; however, their utilization remains relatively unexplored. The quality of the physical environment in transition spaces plays a pivotal role in influencing people’s decision to stay or leave. This study, utilizing the office building at Kunming University of Science and Technology (Chenggong Campus) as a case study, focuses on creating a conducive wind environment within the transition space. Employing Computational Fluid Dynamics (CFD) simulation, the study analyzes contributing factors and proposes optimization strategies. The findings aim to serve as a valuable reference for the design of the transition spaces on university campuses in moderate climate regions, aligning with the heightened emphasis on health-conscious spatial planning in the contemporary era.

“…Because of these characteristics, climbers provide a group of plants that are well-fitted for a performance experiment in an architectural environment [43]. The digital environmental analysis was conducted with Rhinoceros ® and Grasshopper ® supported with the Ladybug ® plugin [38]. The source for environmental data was an EnergyPlus Weather file (.epw) located in the Nowy Port district that was within acceptable distance for such analysis [39].…”

Increasing population and urbanization, with climate change consequences, such as rising temperatures, influence public health and well-being. The search to improve the quality of life in cities becomes one of the priority objectives. A solution can be found in the role of greenery in an urban environment and its impact on human health. This opens a path toward experimentation on microclimate green structures that can be inserted into dense urban spaces providing human and environmental benefits. The article proposes an automated greenery design method combined with rapid prototyping for such interventions. A theoretical analysis of the problem preceded the introduction of the method. The research process was developed in accordance with the main objectives of the CDIO framework (Conceive, Design, Implement, and Operate) with the SiL (Software in the Loop) and HiL (Hardware in the Loop) methods. Moreover, the applied test model allows for complex evaluation in order to ensure quality and directions for further development.

“…The case study site consists of two spots. The first one was examined in previous studies [5] (highlighted in blue in Figure 2) and the second one (green color in Figure 2) is investigated in this case study. In this second step of design, a high-rise building placed on a roundabout is designed.…”

The changing climate is a trigger for architects to reconsider the conventional design approach and possibly enrich it with novel approaches brought by the digital age. Sun analysis for urban planning with wind analysis too, proves inevitable for creating comfortable public spaces and built environment in general. When incorporating wind analysis into the process of architectural/urban design, several crucial pre-requisites determine the use of CFD (Computational Fluid Dynamics) simulations: (1) the demand from the client, (2) the time-space needed for the investigations, (3) the powerful enough hardware, and (4) software that enables a fast, user-friendly interface for parametric investigations. Among the benefits of investigating wind speed and flowlines in the digital environment is the possibility to compare design alternatives very quickly and with the same boundary conditions. Moreover, the popular algorithmic software Grasshopper currently enables wind investigation of the geometry directly in the modeling environment without the need to export the file to a standalone CFD software. This way, multiple design options can be investigated once the parametric geometry is prepared, and the digital wind tunnel is set.
