fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in kenya. the heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in kenya. as part of innovation efforts, several energy-conserving technologies have been developed. a unique cook stove named m...

the municipality of tehran is intending to construct a permanent international flower exhibition. the activities for construction began in the year 2006. the exhibition has three distinct areas namely “northern area”,”southern area” and “central area”. in northern and southern area the flowers are supposed to be preserved and in central area, they will be sold out. in the present st...

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...

this paper applied a non-parametric (data envelopment analysis) method to analyze the efficiency of farmers, discriminate efficient farmers from inefficient ones and to identify wasteful uses of energy in order to optimize the energy inputs for greenhouse cucumber production in lorestan province of iran. data were collected from 27 cucumber producers by using a face-to-face questionnaire.dea cr...

in this paper, a study and design of energy conservation actions and the obtention of energy efficiency titles, according to the italian ministerial decree 20th july 2004, applied to lighting and electrical systemsin a school district managed by perugia province (italy), is presented.specifically, the analysis regarded the replacement of neon lamps with high efficiency ones, and the power facto...

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...

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...
