Saving solutions for windows: The Surveyors analyzed the situation

Large savings in modernization is in the range of windows. Surveyors advise the redevelopment of old buildings and often allow for replacement of windows and thus to the change of a modern double-or even better triple-insulating glass. Which window solution of the question, can detect the Surveyors by a building analysis. He is guided by the Energy Saving Regulation (EnEV), which is part of the energy and climate program of the Federal Government. Remember that the CO2 emissions from buildings are to be reduced by 20 percent (compared to 1990) to the year 2020. To reach the goal, is since October 2009, the intensified EnEV. It sets new limits (such as Wärmedämmung) bei Sanierungen und Neubauten fest. Der Bausachverständige achtet bei der Auswahl des Fensterglases auf den g-Wert — also das technische Maß für den Sonnenenergiegewinn. Ist der g-Wert hoch, heißt das: Die Sonnenstrahlen passieren das Glas relativ ungehindert, was zu solaren Energiegewinnen führt.
