This paper introduces a novel approach to integrate orientation-dependent spectral
properties of daylight in urban planning. These spectral characteristics of light at façades are …

This paper analyses the forecast accuracy of current state-of-the-art, data-driven, spectral
sky models. The aim is threefold:(i) to determine the forecast accuracy of existing spectral …

Spectral power distribution (SPD) of light can play a significant role in people's comfort,
visual performance, as well as their psychological and physiological health. Yet, most …

Various applications in building lighting such as automated daylight systems, dynamic
lighting control systems, lighting simulations, and glare analyzes can be optimized using …

Since the publication of the standard sky luminance distributions (SSLD) that was
consolidated in the ISO 15469: 2004 (E)/CIE S 011/E: 2003, numerous procedures have …

Spectrally and spatially resolved information on daylight is critically important when planning
for non-image forming (NIF) responses. Nevertheless, the availability of such data is scarce …

It is difficult to obtain both sky luminance and solar radiation data, which greatly restrict the
development and utilization of solar resources. In this paper, the functional relationship …

The optimum utilization of solar energy requires effective harvesting of both the direct and
diffuse components of ground-reaching radiation. Although solar beams are typically key …

The characterization of sky conditions according to the CIE Standard General Sky
classification requires knowledge of diffuse luminance angular distribution in the sky vault …

Proper assessment of building façade illumination by natural daylight is a key factor in active
utilization of renewable solar energy. Theoretical modeling of sky luminance distribution …
