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.

“…Therefore, designing good classroom lighting is a crucial and complex challenge for designers. Moreover, incorporating daylight illumination into classrooms increases student satisfaction [36] and helps to conserve energy [37][38][39]. Nevertheless, daylight cannot be present throughout the entire teaching day due to several factors, such as weather conditions, time of day, and building design.…”

“…Daylight also provides various health benefits, such as regulating the body's circadian rhythm [55] and improving health [56], mood [57], and well-being [58]. Conversely, inadequate provision of daylight can lead to adverse effects such as fatigue [39], stress [56], eye strain [59], circadian phase shifting [60], and the advance of Seasonal Affective Disorder (SAD) [61]. Daylighting is essential to creating optimal learning environments that enhance sustainability, while minimising the potential harmful effects of electric lighting [59,62,63].…”

Humans are spending more time indoors than ever due to urbanisation and industrialisation, leading to higher electricity consumption in lighting systems. Recent research has demonstrated the significance of maintaining a balance between daylight and electric light to create an ideal learning environment that can significantly impact students’ academic performance. The objective of this study is to analyse the changes in students’ emotional response depending on the type of lighting in the classroom—whether it is daylight, electric light, or a combination of both. A field study was conducted with 521 university students to assess their affective response to the lighting environment inside their classroom. The results show that students prefer a Clear-efficient lighting environment for writing–reading tasks and a Soft-calm atmosphere for using electronic devices. For the paying attention tasks, a combination of daylighting and electric lighting is determined to be the best solution, while for the tasks of discussing–teamwork, students prefer daylighting. Daylighting is found to be the only lighting option that students like. Despite this, students still consider electric lighting and the combination of daylight and electric light adequate for a classroom. The findings of this study may help educators and designers create learning spaces that promote a positive and stimulating student environment by understanding the relationship between the lighting environment and students’ affective responses.

“…While most studies address the impact of illuminance on the workplace or at the eyes level (e.g., [2]), fewer measured the correlated colour temperature of light (CCT). However, CCT was defined as a predictor for wellbeing and performance as often as illuminance and has been shown to impact both psychological and physiological aspects more frequently than illuminance [3]. For instance, CCT was found to impact the circadian rhythms, crucial to maintain day and night cycles.…”

Properties of light impact both psychological and physiological aspects. In this context, the effects of light’s correlated colour temperature (CCT) appear less studied than the effects of illuminance, although CCT is known to impact circadian rhythms responsible to maintain day and night cycles. Recently, Human-centric lighting (HCL) proposed to endow electric lighting with daylight dynamic characteristics with recognized benefits on physiological rhythms, particularly in reducing blue light exposure at night. Current lack of studies on the psychological effects of CCT prevents from reaching conclusions regarding the psychological aspects of HCL. The present user experiment aims to shed light on the relationship between HCL and personality, acceptance of an automated system to maximise daylight provision and visual comfort perception of occupants in two different buildings and within two types of offices. In this case, participants selected the HCL paradigm with dynamic CCT more often than a standard fixed CCT design, especially in individual offices. Despite being more frequently set and used to diffuse an appropriate light colour, dynamic CCT was assessed to deliver a heterogeneous light and decreased the overall visual comfort of occupants. Still, dynamic CCT was found to increase the acceptance of the automated system while mediating the relationship between personality and acceptance.
