Sustainable architecture is known as an important strategy in recent years and all around the world are cooperating to achieve this by use of natural elements. There are many examples of residential buildings in Iran s past and its traditional architecture that the architecture in the interim of paying attention to aesthetic issues and preserving the natural environment acts in a way that meets...
From 60 decade sustainability issues and sustainable developing have opened a way in scientific meetings associated with environment and urbanization and architecture. Sustainability goals are improving of environment situation , less pollution and at least interference on land and interaction of natural and artificial environment , that most of these cases attracted attention in archite...
the light of the Genius Loci theory. The theory has been verified in many studies by the traditional-Islamic philosophers. Proving the closeness of these two viewpoints in extent and type of the environmental influences on disposition can open a venue for applying the theory of Genius Loci to establish a basis for environmental design in regions with Islamic and traditional cultures. This re...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
The energy performance of radiant slab cooling relative to conventional air systems to be clarified for climates from cold and dry to very hot and humid. EnergyPlus simulations were used to compare the energy performance of 1) radiant slab cooling combined with a dedicated outdoor air system and 2) a variable air volume system. Simulation results show that the radiant slab system provided 10% t...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
background: the phase change materials (pcms) have the appropriate properties for controlling heat strain. one of the well-known pcms is paraffin. this study aimed to design the cooling vest from the cheap commercial paraffin compound and evaluation of its effectiveness under laboratory hot conditions. methods: the cooling vest was made of the polyester fabric and it had 17 aluminum packs. the ...
Paper undertakes software based numerical simulations in two different traditional houses in cold-dry climate of Tabriz and hot-arid climate of Yazd, The Eco Test software chosen for BIM simulations. Case study on real houses instead of hypothetical models can give more tangible results and choosing traditional houses can provide a good opportunity to compare both physical and thermal condition...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Compound climate extremes are receiving increasing attention because of their disproportionate impacts on humans and ecosystems. However, risks assessments generally focus on univariate statistics. We analyze the co-occurrence of hot and dry summers and show that these are correlated, inducing a much higher frequency of concurrent hot and dry summers than what would be assumed from the independ...
