“…Despite the 'harsh' extreme northern climate, creating sealed and secure interiors does not constitute a viable architectural solution, both in social and psychological terms, 6 as spaces presenting an increased connection to the exterior can contribute to their inhabitants' physiological and psychological wellbeing. [7][8][9][10][11][12][13] Interiors should, moreover, take advantage of daily and seasonal variations. 14,15 Light with a strong short wavelength component (blue light) is necessary to maintain proper synchronization of a myriad of biological rhythms through the circadian clock daily entrainment.…”

Daylight can enhance the quality and inhabitability of architecture through a better relationship with the exterior environment, especially by its intensity, chromaticity and ability to synchronize the human circadian clock. Daylight integration in architecture remains a challenge in Nunavik (Quebec, Canada) due to its subarctic climate, photoperiod and solar geometry. The objective of this research is to implement photobiological metrics of light in architectural representations by isolating the photopic (daytime vision) and melanopic (circadian clock) portions of the electromagnetic spectrum, and to spatialize daylight and artificial light in relation to landscapes and indoor architectural spaces. An automated and low-cost capture tool based on Raspberry Pi microcomputers and Camera Modules (RPiCM) captures high dynamic range images, which accurately measure luminance to render human perception. Absolute photopic luminance maps (cd/m2) are supplemented with false colour displays of photopic/melanopic contents of light regarding building surface materials. The research develops photometric captures of absolute photopic and melanopic illuminance (lux, EML). Photobiological metrics of light are integrated into a set of physical properties of lighting patterns to perform light assessments and are ultimately represented as a graphical display to help designers and researchers to evaluate architectural interior–exterior relationships through daylight qualities.

“…As further discussed in the background section, existing methods also require further developments in terms of quantifiable metrics, thresholds, and occupant-centric spatial evaluations [2,20,25]. Metrics and spatial evaluations for view access in space must be developed to show impacts of architectural variables on potential visual experiences of occupants throughout space [25][26][27]. Thus, having an efficient view to outdoors through windows must be evaluated in relation to the potential visual experience of an observer prior to discussing qualities of views or visibility of exterior elements.…”

This paper presents a computational method for spatial visualization and probability evaluations of window view access in architecture based on human eyes’ vision fields and biophilic recommendations. Window view access establishes occupants’ visual connections to outdoors. Window view access has not, yet, been discussed in terms of the typical vision fields and related visual experiences. Occupants’ views of outdoors could change from almost blocked and poor to good, wide, and immersive visions in relation to the binocular focus to monocular (far-) peripheral sights of human eyes. The proposed methodological framework includes spatial visualizations and cumulative distribution functions of window view access based on visual experiences of occupants. The framework is integrated with biophilic recommendations and existing rating systems for view evaluations. As a pilot study, the method is used to evaluate occupants’ view access in a space designed with 15 different configurations of windows and overhangs. Results characterize likelihood of experiencing various field of views (FOVs) in case studies. In particular, window-to-wall-area ratios of between 40% and 70% offer optimum distributions of view access in space by offering 75% likelihoods of experiencing good to wide views and less than 25% probabilities of exposing to poor and almost blocked views. Results show the contribution of the proposed method to informative decision-making processes in architecture.
