building contraventions have become one of the important dilemmas of many cities like tehran. the wide aftereffects of the contraventions and the large cost of removing their negative effects, make the reduction of the possibility of their occurrence essential. this paper tries to find the reasons and roots of building contraventions in order to prevent their occurrence through appropriate plan...

one  of  the  fundamental needs  for  the  human  is  to  have  a  workplace in  which  they  can  do  their  workappropriately. worldwide energy crisis necessitated the construction of official buildings with smaller space and less air ventilation. this led to the reduction in air conditioning, accumulation of the contaminants in indoor, increased exposure, health threat concerning the staff i...

building construction challenge, in recent years, is the reduction of social, economical and environmentalimpacts along with economical nature and increasing life quality, as here sustainable construction is important. pre-fabrication and industrialization are referred as a solution of sustainable construction due to some of its main characteristics consisting of many sustainability aspects. du...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

The present work aims to introduce an efficient set of high spatial resolution (HSR) images in order to more fairly evaluate building detection algorithms. The introduced images are chosen from two recent HSR sensors (QuickBird and GeoEye-1) and based on several challenges of urban areas encountered in building detection such as diversity in building density, building dissociation, building sha...

extended abstract 1. introduction from about the 1950s, extraordinary growth of cities and increase of urban population have led to excessive growth of settlements in cities (muhallab taha, 2001(. this growth caused an unprecedented rise in land prices (zaheri & pour- mohammadi, 2006). land is an essential element in urban expansion and development (vander molen, 2002). therefore, quality and q...

in this research, we investigated basic symptoms of syndrome in illnesses of sick buildings. we designed a questionnaire and asked from male of dormitory residence. questions of the questionnaire were more about known symptoms of buildings (shortness of breath, inflammation, swelling and burning eyes, runny nose, malaise and fatigue, drowsiness, headache) exacerbations time intervals in the res...

The building sector accumulates approximately a third of the final energy consumption. Consequently, the improvement of the energy efficiency in buildings has become an essential instrument in the energy policies to ensure the energy supply in the mid to long term moreover is the most cost-effective strategy available for reducing carbon dioxide emissions This paper is studying the main objecti...
