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; ...

Environmental matters are more complicated. Sustainability of environment requires an integrated approach to decisions making, planning, and management. Therefore, there is a need for a professional and systematic environmental management approach to reducing the consumption of resources. This approach is generally lacking in most universities, and therefore achievement of sustainability become...

Previous research has shown that there is a clear relationship between the urban morphology on one hand and local solar irradiance air temperature other hand. In order to describe climatology its spatial variations sky view factor (SVF) plays key role. This fraction of visible provides an indication street geometry building density. Adding SVF as evaluation element in planning be used coordinat...

The use of Lidar (Light Detection and Ranging), an active light-emitting instrument, is becoming increasingly common for a range of potential applications. Its ability to provide fine resolution spatial and vertical resolution elevation data makes it ideal for a wide range of studies. This paper demonstrates the capability of Lidar data to measure sky view factors (SVF). The Lidar data is used ...

Outdoor thermal conditions influence the quality of life in urban commons. Urban vegetation is an effective way to improve pedestrian comfort tropics as it provides shade, reduces surface heating, improves air quality, and human health. The primary objective this study understand correlation between Sky View Factor (SVF) modifications Outdoor Thermal Comfort (OTC) that could ...

Tropical cities can use urban greening designs featuring trees that provide shade and cooling in hot outdoor environments. The cooling effect involves numerous tree characteristics that are not easy to control during planting design, such as the canopy size and the optical properties of leaves. Planting the appropriate tree species dominates the cooling effects and the human thermal environment...

In many applications, such as in urban physical simulations or in the study of the effect of the solar impact at different scales, models with different levels of detail are required. In this paper we propose an efficient system for quickly computing the Sky View Factor (SVF) for any point inside a large city. To do that, we embed the city into a regular grid, and for each cell we select a subs...

Urban planning must consider the outdoor thermal comfort of city dwellers, particularly in cities where climate and effects change may severely influence human health wellbeing increasingly hot summers. The role urban forest ameliorating this problem is decisive. present study based on a campaign meteorological measurements large number sites using mobile data collection system to allow human-c...

Urbanization transforms simple two-dimensional natural spaces into complex three-dimensional (3D) artificial through intense land use. Hence, urbanization continuously vertical urban settings and the corresponding sky view area. As such, collecting data on their interactions with climate is important. In this study, LiDAR remote sensing was applied to obtain finer-resolution footprints of urban...
