The very first zero-energy houses which were built in the 1970s required complicated and costly technical systems. Today however, experience with low-energy houses has shown a more practical and easier approach: cost-efficient highly insulated houses without any heating systems, called Passive Houses, constitute the standard of the future.

+ | Energy efficiency does not mean that one has to feel cold all the time. Improved efficiency means that it is possible to provide more comfort while consuming less energy at the same time. It is all about intelligent technology and not about having to forgo comfort. [[basics: | ||

Climate change caused by humans is a threat to flora, fauna and our entire civilization. We must therefore reduce net greenhouse gas emissions to a sustainable amount. Possible future solutions in the building sector include zero-carbon / zero-emissions buildings, which are already required in some areas.
