Change extraction of building is needed to revise building data effectively. Many change detection algorithms use height difference analysis using temporal data such as LIDAR. However, remarkable changes of buildings cannot be detected in urban dense areas. On the other hand, building textures might change with higher possibility. However, the change cannot be detected due to influences of shad...

Energy-efficient retrofitting of building envelopes is necessary to reduce global carbon emissions and reach net-zero goals. Cooling energy demand-dominated countries in the GCC region require simple effective strategies sector loads. One such approach using high solar reflective index (SRI) paints retrofit roofs walls. However, hot desert conditions pose a barrier maintaining consistent radiat...

This paper investigates the effect of span cantilevered RC wall, in-plane stiffness roof, layout friction damper support on both response control walls in gymnasiums with metal spatial roofs and proposed evaluation method. According to history analysis results, method was proved be available various formula column base moment modified following appropriate diagram.

Automated 3D building model generation continues to attract research interests in photogrammetry and computer vision. Airborne Light Detection and Ranging (LIDAR) data with increasing point density and accuracy has been recognized as a valuable source for automated 3D building reconstruction. While considerable achievements have been made in roof extraction, limited research has been carried ou...

abstract this papare is resaults of analysing the data which reported from a harvesting project. the site for collecting data is buildings' roofs of azad islamic university of mashhad. a rain gauge and a small reservoir (capacity is 4 cubic meters) were set at this site. then the amount of precipitation and its runoff were measured during two years (from 1386, dey, 23 to 1388, tir, 3).the sampl...

Tehran is the capital city of Iran and its inhabitants are suffering from air pollution.Green roofs can be one of the choices to deal with this problem. In this paper, ability ofgreen roofs in absorbing four air pollutants (PM10, SO2, NO2, and CO2) in Tehran wasvaluated. First, the potential of 1 m2 of a hypothetical green roof in Tehran in absorbingPM10 and SO2 during 1 year was estimated usin...
