nowadays programming and designing of green space of urban area, without considering the criteria for 'optimum standards of green areas is impossible, . in this research, it is tried to determine, the per capita standard rate of green space in different regions of gorgan city, . the applied methedology is an integration of several international and local methods, based on the principles of...

Green roofs are used increasingly to alleviate peaks of water discharge into the sewage systems in urban areas. Surface runoff from roofs contain pollutants from dry and wet deposition, and green roofs offer a possibility to reduce the amounts of pollutants in the water discharged from roofs by degradation and filtering. These pollutants would otherwise enter wastewater treatments plants and ul...

The research focused on the experimental evaluation of Photovoltaic (PV) – green roofs under Mediterranean climate summer conditions. Two autochthonous plants, Gazania rigens and Sedum clavatum, were selected for the PV-green systems while a PV-gravel configuration was used as the reference roof. The above mentioned roofing systems were developed and tested at the University of Lleida, in Spain...

The use of green roof is a great choice in case climate change mitigation and reduction urban heat islands. Positive aspects roofs during winter or the whole year round balance are often overlooked. surface highly insulated flat overcooled night by long wave sky radiation. This radiative cooling increases thermal losses that reduced existence additional layers. composition layers also have thei...

increasing global notices in environmental protection, green supply chain management (gscm) has received much attention by researchers and managers more than the past. commonly, firms have considered cost criteria to select their suppliers. despite the fact that there are various papers considering the formal criteria in supplier selection, there is a few limited numbers considering the environ...

The purpose of this study is to suggest direction for future study of the energy-IT industry that will be used for framework to increase IT utilization in the energy industry. Recently, Green IT is a becoming global issue because of global environmental pollution. Also, IT roles in energy industry are becoming more important. However, the related studies were IT industry oriented that is not su...
