Everyone is now aware that the Earth is “suffering from fever” – this was the headline featured on the front page of a popular German newspaper on 5th November 2006. On 2nd February 2007 the IPCC (Intergovernmental Panel on Climate Change) published its new “Climate Change 2007” report. Slowly the realisation that it is now time to act, is sinking in. Read more..
The primary energy demand determines the impact on the environment. Read more..
Primary energy renewable (PER) is the building assessment system for a future energy supply system dominated by renewable sources.
Primary Energy Renewable (PER)
With energy-efficient construction, the primary energy demand for the application of electricity during the period of use, as well as the embodied energy of the building materials become increasingly significant. Read more..
There are great potentials in improving efficiency, and in addition, energy efficiency and renewable energy go hand in hand for solving the issue of climate protection. Read more..
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. Read more..
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. Read more...
