-**In the case of the Passive House, higher efficiency leads to even more comfort.** "Saving energy" has lost its stigma of being for ascetics only. It is possible to achieve the environmental protection objectives by increasing prosperity and not by abstaining from comfort. In this day and age, this is the only opportunity for putting improvements into practice. This also applies to other areas of energy use, e.g. in transportation. Improved efficiency without sacrificing travelling comfort: in the [[http://www.loremo.com/|"Loremo"]] project, a marketable solution is being developed using this approach.\\

+After 25 yrs of living in the first passive house, the durability of each of the components crucial for the achievements have been checked in a research project. E.g., the U-values of the window glazing have been measured, probes from the roof and the external wall have been taken and analyzed in the laboratory and the thermal envelope was imaged again. All components turned out to be in conditions like new - there was no hint that any of the solutions chosen would not be able to last another 25 yrs [Feist 2020].\\

 Scientists, architects, engineers and other contributors from various disciplines played a part in making the Passive House in Darmstadt-Kranichstein a success. The author would like to express thanks to all those involved. The preparation of the experimental construction was based on the results of many [[basics:the_passive_house_-_historical_review|forerunner]] projects and on findings from building physics, building engineering and systematic computer-assisted systems analysis.\\
