Berlin – Zerbster Straße

In Berlin-Hellersdorf, we carried out a serial renovation of a 5-storey WBS 70 type building (a standardized East German large-panel construction system).
As a result of the measures, energy costs have been reduced by over 40%.

In addition to the facade renovation using prefabricated elements with modern fiber cement cladding, heat pumps were installed, and new cantilevered balconies were added.

The blower door test after renovation yielded a result of n50 = 0.89 1/h, successfully meeting the target (for comparison: target value for new buildings is n50 = 1.5 1/h).


Building class 4 | full floors 5 | residential units 30 | living space 1803 m² | built in 1988
