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...

Amid the information era, energy consumption of IDC Computer Room Air Conditioning (CRAC) system is becoming increasingly serious. Thus there is growing concern over energy saving and consumption reduction. Based on the analysis of the energy saving application of the air conditioning system in the present computer room, a new energy saving method of the IDC CRAC system, which presents energy s...

Demand monitoring equipment is installed in each factory or office, and is linked to the Mitsubishi Electric Head Office via the intranet, where a centralized monitoring server provides comprehensive control (Fig. 1). The multi-demand viewer uses its wide-area control function to collect electric power data from each site in real time, and sends out an alert e-mail when there is a high probabil...

Power consumption is rapidly increased in data centers because the number of data center is increased and more the scale of data center become larger. Therefore, it is one of key research items to reduce power consumption in data center. The peak power of a typical server is around 250 watts. When a server is idle, it continues to use around 60% of the power consumed when in use, though vendors...

This paper established a system dynamics model of energy saving and emission reduction in coal mining area, as well as conducted simulation of different development plans, based on the analysis of energy saving and emission reduction factor of coal production links, of the complex structure of energy saving and emission reduction system in coal mining area, and of the dynamic feed-back mechanis...

Green building is a new building system which based positive cycle of ecological system, green economy, energy-saving society and green technology. [2] The pattern of green building is an important research of architecture style in the present society. The energy-saving in illumination system is an important pattern in energy-saving field and is of great significance. Illumination system is a t...

In 1996, Duke Children's Hospital was in serious trouble. Its $11 million annual operating loss had forced administrators to make cutbacks. As a result, some caregivers felt that the quality of care had deteriorated. Parents' complaints were on the rise. Frustrated staff members were quitting. In this article, Jon Meliones, DCH's chief medical director, candidly describes how his debt-ridden ho...
