Numerical Method for Calculating View Factor between Two Surfaces
Long-wave radiation heat transfer is calculated using a geometrical factor the so-called view factor, which is normally estimated in a simplified way by building simulation programs, especially when there is no information in the literature due to the complexities to solve the double integral which defines the view factor between two surfaces. Analytical solutions are only available in the lite...
متن کاملGoogle Street View and Privacy
The Google Street View technology has proven to be highly controversial. Especially in a lot of European countries – where privacy and data protection laws are far stricter than e.g. in the United States – the launch of Street View has caused many residents and citizens to issues complaints to government officials about the project thereby claiming that it is a massive intrusion upon privacy an...
متن کاملEstimation of Continuous Urban Sky View Factor from Landsat Data Using Shadow Detection
Sky View Factor (SVF, a dimensionless value between 0 and 1 representing obstructed and unobstructed sky, respectively) has an important influence on urban energy balance, and is a key contributor to the Urban Heat Island (UHI) effect experienced by heavily built up regions. Continuous urban SVF maps used in modeling the spatial distribution of UHI can be derived analytically using Lidar data; ...
متن کاملSky-View Factor as a Relief Visualization Technique
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. Analytical hill-shading is the most frequently used relief visualization technique. Although widely accepted, this method has two major drawbacks: identifying details in deep shade...
متن کاملDeveloping a Tool for Analysing and Generating the fittest Urban Morphology based on Sky View Factor and Insolation: With a Case Study on Yazd
Urban morphology, including buildings’ typology and their configuration, affects sky view factor and insolation, which are two of the most influential parameters in urban microclimate. These become even more important in extreme environmental conditions. In this research, challenge was to generate various rule based urban morphologies in a parametric environment. Then, to evaluate them based on...
