“…Therefore, it is not simple to find a suitable ratio of the size of windows and the physical properties of other structures in order to achieve a suitable vision, nor is it simple to prevent glare and minor overheating. The interaction of lighting and overheating in the attic was also addressed by several additional authors [27][28][29][30][31][32][33].…”

The classroom space located in the attic of an old building is the subject of this study. The building was renovated and new spaces were created in the unused attic to expand classrooms. The original space under the sloping roof was not used because its internal headroom was not suitable. During the restoration, the entire original truss was raised gradually (in parts) by 1.2 m. This created a space with an entire area that can be used for classrooms. Continuous strips of vertical windows measuring 860/600 mm were installed in the space which enable a visual connection between the interior space and the exterior. At roof level, there are also two rows of skylights above each other which ensure enough daylight is present but create unpleasant overheating in the summer. The purpose of this study is to find a way to optimize the shading of transparent surfaces and the heat accumulation of building structures in order to achieve suitable interior conditions in the attic. This task was achieved by shading the windows in the attic. Shaded windows decrease illumination by 82% compared to unshaded ones. The percentage decrease in illumination is more significant than the decrease in the maximum temperature due to overheating. Additionally, the maximum temperature in the attic drops by only 31% if vertical and skylight windows are shaded with external blinds compared to unshaded windows. The minimum air temperature reached in the attic also drops by 26%. In order for users in the attic space to feel comfortable, it is necessary to use HVAC equipment in addition to the design of suitably built structures and window shading.

Design methods, frameworks, and green building certifications have been developed to create a sustainable built environment. Despite sustainability advancements, urgent action remains necessary due to climate change and the high impact of the built environment. Regenerative Design represents a shift from current practices focused on reducing environmental impacts, as it aims to generate positive effects on both human and natural systems. Although digital design methods are commonly employed in sustainable design practice and research, there is presently no established framework to guide a digital regenerative design process. This study provides an analysis of existing literature on regenerative design and digital design methods and presents a framework based on building information modelling (BIM) methodology and computational design methods, that can be applied to both urban and building design. This framework identifies digital tools and organizes indicators based on the pillars of climate, people, and nature for regenerative design, drawing upon a comprehensive analysis of literature, including standards, sustainability frameworks and research studies. The framework is illustrated through a case study evaluation. The paper also highlights the potential and limitations of digital methods concerning regenerative design and suggests possibilities for future expansion by incorporating additional quantifiable indicators that reflect research developments, to achieve positive outcomes.
