according to research, between 15 to 20 percent of the total energy consumption of every country is used for residential spaces. this amount is explanatory of the high cost and will follow the destruction of natural resources and environmental demolition. the aim of this research is to recognize earth thermal ability and its usage in public buildings and especially in private buildings in order...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

Energy consumption is a major and costly problem in data centers. For many workloads, a large fraction of energy goes to powering idle machines that are not doing any useful work. There are two causes of this inefficiency: low server utilization and a lack of power proportionality. We focus on addressing this problem for two workloads: (1) a traditional, front-end web server workload and (2) an...

The demand for mobile computer power has exploded in the recent years. Variable length VLIW processors offer the necessary performance at low power. Software optimizations are necessary to further decrease the energy consumption. In this article we present a compiler optimization which reduces the dynamic power dissipation resulting from the switching activities during instruction fetch. Energy...

Flip-ops are one of the most power-consuming components of digital circuits. Even when there is no activity at their inputs, the mere triggering of the clock produces a signiicant waste of energy. This paper presents some techniques to reduce power consumption by selectively deactivating the clock when ip-ops do not have to change their value. Several ip-op structures are proposed and criteria ...
