摘要: The key parameters that may influence building energy performance is studied by comparing the building energy data of college buildings in two different regions (the USA and China). By introducing data-orientated approach, a study of a set of on-campus building energy demand and consumption is conducted for cooling, heating and electricity. In addition, the heating, ventilation and air conditioning (HVAC) and lighting systems are studied in great detail. The breakdown analyses of the current energy consumption data are used to focus the investigation on critical issues. The analysis shows that the energy consumption of college buildings in the USA can be 3–5 times more than that of college buildings in China. The over-high energy consumption in campus buildings in the USA is mainly caused by operation schedule, system style, cooling and heating counteraction and sensor/actuator faults in the control systems, which also leads to the discussion of energy difference on the concept of “full control” or “local improvement” in building environment control. The study also indicates that the building energy efficiency can only be achieved by adjusting the demand according to natural conditions, encouraging green life behaviors, and developing relative technical solutions coordinated with the thrift culture and human behavior.

摘要: 随着互联网的负载高速增长和各种应用的日益丰富,为提供方便、快捷的互联网接入服务,现有的网络结构已经变得相当复杂和多样,这给网络管理提出了新的挑战。为了应对这一挑战,软件定义网络的概念被提出,并被认为是一种有前景的解决方案。在软件定义网络结构中,网络控制域和数据传输域是分开的;所有的网络设备被抽象化,通过一个集中式的控制器来进行管理。通过使用软件定义网络的结构,网络管理变得灵活和高效,因此可以潜在地提升网络性能。为了充分利用软件定义网络的优势,最近又提出了软件定义无线网络结构。本文首先分析在不同无线网络中软件定义网络结构的应用。然后讨论在基于软件定义网络结构的无线网络中使性能提升的几个关键技术环节。最后,提出一些关于软件定义无线网络可能的未来研究方向。
