A new sustainable building standardHow many similar houses can be produced within 30 years with the surplus electricity of one house? The replication factor provides the answer.There is a new building standard for this. I am now in initial negotiations to implement this building standard in software. In other words, a kind of energy certificate calculator where the respective house is entered. Then some numbers come out, as with the usual energy certificate calculators. The most important number here is the replication factor. Replication factor means how many houses of the same type can I build in 30 years with the surplus power of one house. This is calculated very strictly, because the house also takes into account the mobility of residents. You can not swindle that surplus in the summer is used 1:1 in the winter. Because everyone knows: strawberries are much cheaper in June than in December. Why? Because the strawberries of June have to be stored expensively, and therefore they are much more expensive in December. We have the same effect with renewable energy. Solar energy, hydropower, both are stronger in the summer. Only wind energy is a bit stronger in winter, but we can't expand so much wind energy that it balances out. Therefore, with this building standard, we have an exchange factor of 6:1, which means that you have to feed in 6 kWh in the summer so that you are allowed to consume 1 kWh in the winter, balance-wise. The replication factor turns especially against a strange German term: Die Bauscham, oh, you should be embarrassed when you build something, so many resources. The replication factor says the exact opposite. If such a house is built, then you can build with the surplus energy of the one house in 30 years, for example, 2 other houses.
