本文介绍了在德国如何采用楼宇自动化技术实现建筑物节能。节约能源是摆在人类面前的一个十分重要的课题、由于石油、天然气和煤等传统能源的过度开发,使能源资源急剧下降,造成能源价格越来越高。此外,在能源的开发和消耗过程中造成的空气污染和温室效应,也是我们必须解决的问题。 This article describes how building automation can be used to save energy in buildings in Germany. Saving energy is a very important issue for mankind. As a result of the over-exploitation of traditional energy sources such as oil, natural gas and coal, the energy resources have dropped sharply, resulting in higher and higher energy prices. In addition, the air pollution and the greenhouse effect caused by energy development and consumption are also issues that we must solve.
