Problem
The 12-party house in Spremberg was to be completely renovated in 1999. The aim was to improve energy efficiency and to permanently protect the facade from algae and moss.
Due to the location directly under large trees, the client wanted to ensure that the energy-efficient renovation would not further exacerbate the algae problem. A lasting diffusion openness of the facade was therefore a must.
Solution
The owner of the property is a painter himself and a recognized building protection expert. At the time, he deliberately decided against additional insulation and instead opted inside and out for ClimateCoating®.
The reasoning behind this was as follows: The 49cm-thick stone walls already provided the required insulation performance and, in combination with the coating, the facade would remain open to diffusion. The coating would ensure optimum moisture management on and in the wall to protect structural health and reduce heating costs due to permanent wall and plaster dryness. The coating would also protect the facade from algae and moss in the long term, despite its location under trees.
Result
After implementation, the building was monitored for seven years by a working group from FHTW Berlin and FH-Lausitz in Cottbus and the heating energy consumption was analyzed in detail. Not only the heating costs were taken into account, but also weather data and building plans.
The evaluation revealed a clear picture: the energy consumption was 28% below the requirements of the Energy Saving Regulation at the time. For the residents, this still results in very low heating costs with a maximum feel-good climate.
And the aesthetic quality of the facade remains virtually unchanged after a quarter of a century. Pictures from April 2024 impressively demonstrate that the facade still looks as good as new - quite different from the comparison properties on the same street, which were painted in the 2000s! And the knowledgeable owner expects it to remain so for another 20-25 years.
