Photogrammetric refinement of laser-based building roof contours
(2013-08-15)
In this paper a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne laser scanning data. It is assumed that laser-derived planar faces of roofs are potentially accurate, while ...
Adaptability of photovoltaic mono-polycrystalline solar panels and photovoltaic roof tiles on dwelling roofs of real estate developments
(2019)
The use of photovoltaic (PV) technology in urban areas is an appropriate way to optimize the use of solar energy, since the energy conversion system is located in the same place as the demand. Thus, the losses caused by ...
Snake‐based model for automatic roof boundary extraction in the object space integrating a high‐resolution aerial images stereo pair and 3d roof models
(2021-04-02)
The accelerated urban development over the last decades has made it necessary to update spatial information rapidly and constantly. Therefore, citiesʹ three‐dimensional models have been widely used as a study base for ...
Telhados verdes: análise comparativa de custo com sistemas tradicionais de cobertura
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2012-11-09)
Along with the growth of urban occupation and the green areas reduction around the cities comes the need to develop new technologies to reduce the environmental impacts caused by buildings construction and maintenance. The ...
Solar performance of hemispherical vault roofs
(Building and Environment, 2003)
In hot climates, the improvement of comfort by passive solar techniques is a very important issue. In many parts of the world such as the Middle East, vault roofs are widely used in construction. The solar and energy ...
Analysis of roof thermal performance with innovative technology
(Turkish Academy of Science, 2021)
The roof is the surface most exposed to solar radiation in a home, therefore evaluating the thermal performance of different roofing technologies can significantly improve the building´s thermo-energetic behavior. This ...
Building roof contour extraction from LiDAR data
(2011-12-01)
This paper proposes a method for the automatic extraction of building roof contours from a LiDAR-derived digital surface model (DSM). The method is based on two steps. First, to detect aboveground objects (buildings, trees, ...

Host–parasitoid interactions on urban roofs: an experimental evaluation to determine plant patch colonisation and resource exploitation
(Wiley, 2015-09)
1. In cities, green roofs may favour an increase in the local diversity, although the role they play on host–parasitoid interactions is still unclear. Here, we tested the hypothesis that the specialist leaf-miner Liriomyza ...
