Sky-View Factor as a Relief Visualization Technique [PDF]

Remote Sensing, 2011
Remote sensing has become the most important data source for the digital elevation model (DEM) generation. DEM analyses can be applied in various fields and many of them require appropriate DEM visualization support.

Automatic Sky View Factor Estimation from Street View Photographs—A Big Data Approach [PDF]

Remote Sensing, 2017
Hemispherical (fisheye) photography is a well-established approach for estimating the sky view factor (SVF). High-resolution urban models from LiDAR and oblique airborne photogrammetry can provide continuous SVF estimates over a large urban area, but ...

View Factors of Flat Collectors, Including Photovoltaics, Visible to Partial Sky

Energies, 2022
The sky view factor of collectors in photovoltaic (PV) fields is a parameter that determines the amount of incident diffuse radiation. The diffuse radiation may contribute significantly to the generated electric energy.

Sky View Factor footprints for urban climate modeling [PDF]

Urban Climate, 2018
Abstract Urban morphology is an important multidimensional variable to consider in climate modeling and observations, because it significantly drives the local and micro-scale climatic variability in cities. Urban form can be described through urban canopy parameters (UCPs) that resolve the spatial heterogeneity of cities by specifying the 3 ...

Evaluating the Annual Effect of the Sky View Factor on the Indoor Thermal Environment of Residential Buildings by Envi-met

Buildings, 2022
The effect of the sky view factor (SVF) on outdoor thermal comfort has been extensively explored, while its impact on the indoor thermal environment is ignored.

Sky view factor calculations and its application in urban heat island studies [PDF]

Urban Climate, 2019
The sky view factor (SVF) is essential to describe the urban climatology at scales below 100m. This proxy for net radiation depends on the height of the obstacles in its surroundings.

The Effect of Walls on the Sky View Factors of Photovoltaic Systems

Energies
Photovoltaic collectors deployed in multiple rows and near the structure’s walls are obscured from the receiving part of the diffuse skylight. Obscuring part of the diffuse skylight to the collectors decreases the incident diffuse radiation and thus ...

Effects of urban street geometry and traditional kabalti passages on building surface temperature in a hot-dry climate [PDF]

Scientific Reports
In hot climate regions, the direct impact of solar radiation on building surfaces, including heat absorption and storage, negatively impacts outdoor comfort and the living conditions of urban residents.

A fast approach for large-scale Sky View Factor estimation using street view images

Building and Environment, 2018
Abstract Sky View Factor (SVF) is one of the most useful urban spatial indicators for radiation and thermal environmental assessment. Estimating SVF with circular fish-eye photos is straightforward and convenient and can account for obstruction of vegetation and other urban infrastructures.

Bioclimatic comfort and solar responsive urban design in the traditional street texture of Diyarbakir’s Suriçi region [PDF]

Scientific Reports
People in urban areas (such as streets, parks, semi-open and enclosed spaces) are exposed to varying microclimatic conditions. These conditions change depending on environmental characteristics and directly affect individuals’ bioclimatic comfort levels.
