| Construction rules tomorrowFor conventional present houses will be in 100 years for certain no permit to built. |

But are present low energy houes good enough, at the strict rules in a solar energy civilization in 100 years?
Let's look on 100 years development at cars. Daimlers first car could today not brought in the traffic as a new car, because of the exhaust gas norms. But that's not all. Daimlers first car would today not be allowed to drive on the highway. The old Daimler can not reach the minimum speed of 40 km/h. So the usage of the highway is simple forbidden for carriages with horse or carriages without horse like the first car. Can there will be a similar development at the construction rules? With security! A constructor around 1960 would have laughed about a prognosis of current construction rules. Wall with a heat transmission value below 0,5 Watt per m² Kelvin, the roof even better than 0,3 Watt per m² K, where is such possible? Somebody from the time, where people did not know that crude oil is a very limited reserve energy. But this are rooles in the Salzburg heat energy protection law from 1992. But even this rule could not create much enthusiasm in Sweden. Since 1975 are there 0,3 Watt per m² K for the walls and 0,2 Watt m² K for the roof the upper limit. Why are the Swedens happay or frustrated about construction regulations in other countries? Because of the acid rain from the southern countries. So our house should be better than this construction rules: |
