“…78 The authors noted a reproducibility error in ALFA , unresolved at the time of their study. It was also shown that under clear sky conditions ALFA tends to overestimate the irradiance, 99 even though the spectral characteristics are well represented. 74 For electric light simulations, the errors in spectral irradiance were larger than the ±20% range, with ALFA being more accurate due to the higher spectral resolution.…”

“…They claim that for clear skies spectral information of each patch of the sky dome is needed for accurate daylight simulations. In contrast, Pierson et al 99 found that the assumption of a constant D65 was reasonably accurate in simulating melanopic EDI indoors in a variety of sky conditions (clear, hazy, overcast, rainy). They note that, in the conditions that they tested, accurately simulating quantity of light (irradiance) had a larger impact to the result than accurately simulating spectrum.…”

“…79 However, when the spectral irradiance was used to calculate relevant NIF metrics, these differences vanished and most errors of both tools were within the ±20% range. 99 Another in-house spectral simulation software for electric light was developed by Kim et al 71 called Colour Quality Assessment Tool (CQAT), but it is limited to a simple geometry and diffuse materials.…”

Light affects many aspects of human physiology, through the non-image-forming (NIF) pathway. To account for this pathway, lighting design simulation tools need to combine several luminous and temporal factors to predict how architectural and lighting design decisions affect eye-level light exposure. Based on a systematic literature review, containing 55 journal and conference papers, the state-of-the-art towards implementing lighting beyond vision in computer simulation workflows for building design is presented. The review shows that, while interest in simulating the NIF effects of light on people is increasing, there is not a common method to perform these simulations. Gaps were identified in the currently available simulation workflows in relation to metrics, software and approaches for predicting NIF effects of light in the context of the building design.

“…However, Lark, with its 9-channel approach, offers advantages over ALFA in this study due to its capacity to benefit from the Grasshopper/Rhino visual language programme environment, enabling flexibility and versatility in options. Notably, a study by Pierson et al [ 56 ] demonstrated that Lark, although slower than ALFA, produces more accurate results under daylight conditions. The validation of Lark has also undergone examination, as documented in previous studies [ [57] , [58] , [59] , [60] ].…”

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.
