Daylight in classrooms is a critical factor in school design, in terms of its impact on students’ health, learning and visual performance. Providing adequate amount of evenly distributed daylight and glare prevention are important challenges in classroom design. Window configuration significantly affects the intensity and uniformity of daylight. This paper aims to investigate the effect o...

This paper presents an overview of observed distresses on low slope roofing systems collected for the Building Envelope Life Cycle Asset Management (BELCAM) project. The data include over 14,000 visible distresses from 600 roofs from seven different climatic regions across Canada. The distresses encountered for built up roofs, modified bituminous roofs and a limited number of single-ply roofing...

Reducing the number of roof fall injuries is a goal of the NIOSH mine safety research program. Central to this effort is the development of assessment techniques to help identify the nature of the risks associated with working under potentially hazardous roof conditions. This paper discusses a method to determine the roof fall risk using a qualitative risk-analysis technique. The ability to det...

green space, as a social development indicator has environmental, social, cultural, economical, and skeletal aspects and to be able to play its role effectively, the first and most important step is to select an appropriate site for it. site selection necessitates stability analysis of urban green space. the main three steps are identifying stability factors, ahp-based weighting factors and lay...

the rapid change of land use and land cover in the metropolitan area of tehran has influenced the distribution pattern of land surface temperature (lst). in this study, a spatial autocorrelation analysis is adopted to process the spatial-temporal changes of lst and normalized difference vegetation index (ndvi) in tehran during the period of 1987 to 2010. global spatial autocorrelation analysis ...
