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...

Using panel data on investment of firms in energy saving technology, we measure the impact of the payback period of the technology on the probability to adopt the technology in the absence of tax and subsidy incentives. We find that the decision rules to adopt energy saving technology differs substantially between different types of firms, i.e. for-profit/notfor-profit as the decision to adopt ...

Energy saving and the protection of environment for sustainable society is now global agenda, that we must achieve for the next generation and for our Earth. This activity around IT and ICT industry is called as “Green IT/ICT”. Though the most of the Green IT/ICT would focus on the energy saving “of” IT/ICT equipments, we are focusing on the energy saving “by” IT/ICT technologies. The real targ...

The geographic routing technology is good for the self-organizing and large-scale Wireless Sensor Networks(WSNs), and the energy-limited sensor nodes require the energy used for routing to be minimum. In this paper a new energy-efficient geographic routing algorithm is proposed and it is distributed and based on the geographic routing, the topology characteristics of the network and the wireles...
