The basic developing objects of modern society are low carbon and energy saving. We must change the traditional high energy consuming building ways into modern novel energy saving buildings. In this paper, the development of modern building energy saving technology was reviewed and concluded. On this basis, designing ways and methods for energy saving system was proposed from the points of wall...

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...

buildings play an important role in the energy demand sector. due to the increase of environmentalconcerns and renewable energy sources restriction, lighting control systems will play an important role in the reductionof energy consumption of the lighting without impeding comfort goals. lighting control systems can control lightingconsumption according to the type of building, adequate luminanc...

Saving energy of the portable devices including smartphones have become a critical design problem. Modern components of these devices are suffering from hunger of power. In this purpose, many researchers studied how to minimize the energy consumption. Dynamic voltage and frequency scaling (DVFS) is an effective energy saving technique for these portable devices. This paper proposes a simple but...

Optimization of energy production systems is a relevant issue that must be considered in order to follow the fossil fuels consumption reduction policies and CO2 emission regulation. Increasing electricity production from renewable resources (e.g., photovoltaic systems and wind farms) is desirable but its unpredictability is a cause of problems for the main grid stability. A system with multiple...
