The illumination of the environment undergoes both intensity and spectral changes during the 24 h cycle of a day. Daylight spectral power distributions are well described by low-dimensional models such as the CIE (Commission Internationale de l'Éclairage) daylight model, but the performance of this model in non-daylight regimes is not characterised. We measured downwelling spectral irradiance a...

The influence of light sources on digital camera-based spectral estimation is explored. CIE daylight and non-CIE illuminants with different Correlated Color Temperature (CCT) are first tested comparatively, results indicate that CCT can be used to describe the performance for but not applicable all types sources. To further investigate mechanism effects estimation, several handmade special shap...

Photodynamic therapy (PDT) is an attractive therapy for non-melanoma skin cancers including actinic keratoses (AKs) because it allows treatment of large areas; it has a high response rate and results in an excellent cosmesis. However, conventional PDT for AKs is associated with inconveniently long clinic visits and discomfort during therapy. In this article, we critically review daylight-mediat...

Atrium is a popular architectural feature utilized widely by building designers and owners to bring various benefits such as adequate daylight, circulation spaces and surfaces for landscape applications. But atrium problems in tropical climates such as excessive daylight, glare and high temperature, which lead to increase building energy demand, have been reported. Atrium has been used with var...

Daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. Providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. Window configuration significantly affects the intensity and uniformity of daylight. This paper aims to investigate the effect o...

Seedlings of fifteen species of shrubs and small trees, commonly found in open sites and early stages of secondary succession, were grown in a glasshouse under light intensities of 16% and 66% full daylight, and their growth parameters (height, number of leaves, dry weight, mean relative growth rate) recorded. Three species from open habitats, Coprosma robusta and Dodonaea viscosa, and an adven...

The architectural form of the façade determines its identity as well interactions with micro-climate forces ambient environment, such solar radiation. dynamic nature daylight and occupants' positions can cause some issues heat gains visual discomfort, which need to be controlled in real-time operation. Improving performance preventing discomfort for multiple occupants simultaneously is challeng...

Climate-Based Daylight Modelling (CBDM) methods have been validated against long-term measurements in laboratory settings and found to exhibit errors small enough make such assessments useful for daylight performance prediction. However, real occupied spaces are affected by a higher number of uncertainties than or controlled conditions. This study aims at validating CBDM collected an classroom ...
