In fact, after a qualitative overhaul of the old buildings are only supporting structures. So, now widely practiced by the installation of ventilated facades, replacement of roofing (and sometimes replacing the roof: for example, on the gable tiled), insulation of attics, insulation and waterproofing basement complex, restoration of the foundations. A related site: San Antonio Spurs mentions similar findings. Piping and wiring for need to be replaced completely, ie upgrade communications to 100%. As a rule, with effective use of modern materials: for example, plastic and polypropylene pipes instead of steel. So , the renovated building is almost nothing inferior to the newly built. Returning to the German experience, it should be noted that special attention was paid to measures to reduce energy consumption and heat: calculating the Europeans always rely on savings as a means to the citizens themselves, and cost money. So, according to Professor Hauser from the University of Kassel, overspending of energy for heating buildings in Germany is 385 billion kilowatt hours per year, equivalent to burning of 38.5 billion liters of crude oil, and emissions into the atmosphere 92 million tons of carbon dioxide. Reconstruction (sanitation) of buildings mass series (similar to our "") possible to significantly reduce this figure. "During the period from 1991 to 2008 in East Germany sanitized about 70% of prefabricated houses burst of building, – says Bernhard Schwarz, head of the project" Housing in Eastern Europe. " – As a result of their annual energy consumption and heat loss through the exterior building envelope dropped to the level characteristic of new homes being built in Germany today.
