“…In addition, they noted a superiority of one typology in comparison with other different typologies in both EUI and OTCA studies [17]. Mirzabeigi and Razkenari (2022) proposed an optimization framework using Grasshopper plugins, Ladybug tools and Eddy3d to compare six varying urban typologies of low-rise, mid-rise and high-rise categories based on OTC and EUI performance and identify a set of the best design solutions in the conceptual urban typologies in Syracuse, United States [37].…”

With an increasing awareness of urban health and well-being, this study highlights the growing importance of considering environmental quality in urban design beyond mere energy performance. This study integrates outdoor and indoor quality by investigating the effect of design parameters at an urban block scale (building form restricted to width and length as rectangular and square, building orientation, block orientation, building combination, building height, facade length, built-up percentage, setbacks, and canyon aspect ratio) on outdoor thermal comfort and energy use intensity. In addition, it explains the different correlations between outdoor thermal comfort and energy use intensity in different urban block designs in a hot-summer Mediterranean climate in Jordan. The study adopts a performance-driven approach using simulation tools of Ladybug, Honeybee, Dragonfly, and Eddy3d plugins across the grasshopper interface and evaluates 59 different urban block designs with nine different orientations (0°, 1°, 45°, 85°, 87°, 90°, 355°, 358°, and 359°). The results show that there is a positive correlation between the canyon aspect ratio and the environmental performance of the urban block designs. North–south street canyons are more effective at enhancing microclimates. Negatively increasing the street aspect ratio by more than four affected outdoor thermal comfort by increasing longwave radiation. Further results suggest a positive correlation between the compactness of urban blocks and their environmental performance, with north–south street canyons found to be more effective in enhancing microclimates. The study emphasizes the need to understand the distribution of open spaces formed by buildings and to strike a balance between day and night, as well as summer and winter conditions in outdoor spaces.

“…The originality of the study lies in focusing on the role of emissivity in building façades with relation to effects on outdoor comfort conditions, which is generally investigated by paying more attention to horizontal surfaces, namely roofs [97,98] and paved spaces [99]. The main focus of the scientific literature is usually on the specific albedo of materials [100], on the analysis of UHI patterns and intensities with relation to urban typologies [101], and on mitigation techniques and technologies [102], while the role of vertical surfaces is basically addressed to explore cool façade optimization [103]. U. Dietrich particularly focused on the impacts of the materials adopted for building façades in urban street canyons where the Urban Thermal Comfort Index (UTCI) is investigated [104].…”

This article examines the influence of the emissivity of façade materials on outdoor microclimatic comfort. The developed methodology is based on the collection of input data regarding the site, the geometrical and technological characterization of the building envelope and the definition of the associated emissivity, the development of alternative emissivity-driven scenarios, the scenario simulation to obtain Outdoor Microclimate Maps (OMMs), and their interpretation and discussion. The operative steps of the proposed simplified method are applied to a specific case study in the city of Bologna made of a mix of buildings, including some towers overlooking an inner courtyard. The emissivity of the façade materials is assumed as the main variable. The results show how, by properly addressing the design choices, it is possible to achieve significant improvements in the outdoor microclimate for the space in-between the considered volumes.

“…A starting point for multispecies design intervention is the building envelope. This is because building envelopes play a significant role in mediating indoor and outdoor environments, enhancing building performance, and potentially supporting the colonization of living organisms (Mahrous et al, 2022;Mirzabeigi & Razkenari, 2022). Multi-species building envelope design equally accounts for human requirements and the requirements of other living organisms (Canepa et al, 2022;Perini et al, 2021;Weisser et al, 2022).…”

Anthropic activities negatively impact natural and artificial ecosystems, necessitating interdisciplinary mitigation strategies such as multi-species building envelope designs. This paper introduces a computational multi-criteria decision-making (MCDM) methodology to support these envelope designs. We also propose a nested set strategy for key performance indicators (KPI) to strategically measure architectural and ecological performances. We integrate the strategy into a proposed hybrid MCDM methodology using computational design tools. The methodology was tested using a generic volume case study described by an architectural and ecological objective with varied priorities. Initial results highlight the computational interoperability of hybrid MCDM, informed by nested KPI set priorities, as support for multi-species building envelope designs.
