“…It is a graphical algorithm editor that allows designers and researchers to create parametric forms of varying complexity. Grasshopper has been used in many studies for various purposes, such as analysing daylighting, energy consumption and calculating cooling and heating (Nadiri et al , 2019; Pilechiha et al , 2020). The available EnergyPlus Weather file for Shiraz (FA_Fars, 2018) was imported via Ladybug to analyse the amount of indoor ATC in each zone.…”

PurposeIn vernacular buildings, many climatic and passive solutions have been used to create indoor thermal comfort. Seasonal occupant movement is an example of a traditional response to increasing thermal comfort. This article investigates the influence of these user behaviours on thermal comfort in courtyard houses.Design/methodology/approachParametric models of three different scenarios of courtyard houses are simulated. The courtyard houses are located in Shiraz, Iran, and share the same orientation and construction materials. To enhance the accuracy of the study, the indoor adaptive thermal comfort (ATC) analysis is performed with three different window-to-wall ratios (WWR) of 25, 50 and 75%. The ACT analysis is performed on an hourly basis for summer and winter scenarios.FindingsThe results demonstrate that the indoor ATC is 8.3% higher in winter than in the summer in the seasonal zones. During the summer, the amount of ATC is relatively sustained in all zones. Unlike common beliefs, seasonal movement can enhance the ATC, especially during winter, specifically in the northern part of the courtyard. In northern zones, the seasonal movement of occupants improves the indoor ATC from 10.1 to 23.7%, and in southern zones, the improvement is from 2.2 to 4.8%.Originality/valueThis research presents a new numerical investigation into occupants' seasonal movements in courtyard houses during summer and winter. It provides a precise pattern to show how much this seasonal movement can affect the habitant's ATC.

“…Berk Ekici et al [42] reviewed 100 articles and pointed out that EC was the main optimiza-tion method used in review papers, and the most common PCA research topic was the building's skin. At present, use of a multiobjective optimization engine combined with the Grasshopper platform and a genetic algorithm is relatively common in the design and research of this field [36]. Jalali et al [50] used the multiobjective optimization of the strength Pareto evolutionary algorithm 2 (SPEA2) algorithm to provide the amount of solar radiation received by the building envelope, as well as the effective interior space and design shape factor based on the cooling load, heat load, and natural light provided to the building, to optimize the building façade.…”

The lighting conditions of a library directly affect the users’ spatial experience, with glass curtain walls being widely used in the design of library skins. Although glass curtain walls have been extensively adopted, they increase indoor sun exposure and glare. Considering sunlight duration and radiation as the design basis, this study employs the Rhino and Grasshopper parametric platforms to parametrically design a library with a dynamic shading skin. Specifically, our design utilizes modular shading components that can change depending on the simulated sunlight data at different times. Additionally, a new optimal design strategy has been developed to enhance the environmental lighting performance of the library. The simulation results highlight that the indoor environmental lighting performance, under dynamic epidermal shading and based on sunlight duration data, is better for east–west, north–south, and east–west orientations on the summer solstice and the winter solstice. Meanwhile, the indoor environmental lighting performance, under dynamic epidermal shading based on daylight radiation data, is better for north–south orientation on the winter solstice. Overall, this study uses parameterization to integrate building simulation and architectural design to improve a building’s lighting performance.

“…Gu et al proposed a simplified modeling method based on a three-stage automatic genetic algorithm which automatically determines the structural characteristic parameters iteratively by taking the period and mode shape as input [66]. GAs have been widely used to solve problems related to building optimization [41,67,68]. The GA based on the MATLAB platform is convenient for architects to control architectural forms and explore their performance relationships due to a series of ad-vantages such as the plug-in of the platform, operability of parametric models, convenience of data conversion, and visualization of simulation results [69][70][71].…”

Carbon-neutral architectural design focuses on rationally utilizing the building’s surroundings to reduce its environmental impact. Resilient ventilation systems, developed according to the thermal comfort requirements of building energy-saving research, have few applications. We studied the Jin-an Shopping Mall in Harbin and established the middle point height (h), middle point horizontal location (d), roof angle (α), and exposure to floor ratio (k) as the morphological parameters of the atrium. Using computational fluid dynamics (CFD), the mean radiant temperature (MRT), and the universal thermal climate index calculations (UTCI), this program was set to switch off air conditioning when the resilient ventilation met the thermal comfort requirement to achieve energy savings. The energy-saving efficiency (U) was calculated based on the energy consumption of the original model, and U could reach 7.34–9.64% according to the simulation and prediction. This study provides methods and a theoretical basis for renovating other commercial complexes to improve comfort and control energy consumption.
