Apartment building in Spremberg


During the modernization of the dwelling house with 12 residential units from the year 1927, the 49er brick walls were coated with ThermoShield Exterieur and the roof slopes were coated with ThermoShield Interieur. Despite renouncing a facade insulation, the building has no higher consumption values than the neighboring insulated buildings.
 

 

With regard to energy efficiency, subjective perceptions are confirmed by low heating bills. In addition, the comparison with the heating bills for neighboring residential blocks over a period of 4-5 years shows that the 8 cm thick thermal insulation made of polystyrene which was almost identical in construction at that time (~ 1960, block construction with huts), in connection with the insulation of the basement ceiling, did not lead to more savings. If the production costs of facade insulation and a Thermo-Shield paint are included in the evaluation, an excellent cost-benefit ratio is revealed.

For the energy consumption analysis there were very extensive data available here: heating costs accounts for 4 and 5 years, precise regional weather data, extensive construction plans (ground plans, sections, views). In addition, the enveloping surfaces (roof and dormers, massive exterior walls, plastic windows, basement ceiling) were inspected.

On the basis of the good data base, one of the first energy certificates was issued in 2006. This certifies a consumption which is 28% below the demand calculated according to EnEV. This evaluation of 2005/2006 as well as the history of the measurement of the k-value (today: U-value) and its use in the calculation for the proof of heat resistance, gave, besides other analyzes, safety in the evaluation. A validation was carried out to the effect that 2 independent scientific working groups, the FHTW Berlin and the FH Lausitz in Cottbus, came to comparable results.

This multi-family house in 03130 Spremberg, Artur-Becker-Ring 58/60, is a multi-family dwelling built in conventional construction with a construction year 1927. It comprises 12 residential units with a total of 816 m² of living space with around 4,200 m³ of gross floor space and 13 m of ridge height. After it was empty for a few years, it was modernized in 1999. The building is located at 8 ° deviation of the longitudinal axis in the north axis. It was noticeable at the inspection date on 4 November 2005 that, despite the nearby tree population, no algae and other micro-organisms were visible on the facade.

The 49 cm brick wall walls with lime-cement plaster were coated with ThermoShield Exterieur. The roof slopes and the walls in the DG were painted with a ThermoShield Interieur. The basement ceiling is an uninsulated solid cover (about 80 cm above ground), the roof insulation consists of 4-6 cm loosely laid mineral wool. There are thermal bridges in the area of the balcony slats on the courtyard side. There are 12 balconies of 6,2 m with 12 cm of reinforced concrete slabs, which have been placed on the external walls.

The modernization to the extent described has proven to be very effective and economical, since additional facade insulation has been dispensed with.The house management: "Such a low calculation of incidental costs we do not have usually. For example, An 8-family house (new building) is more expensive than this 12-family house. "The tenants are very satisfied. Axel T .: "Even in the winter only 3 radiators run in the apartment, but only on 2-3. A super heat bill. "Mrs. B. had previously lived in a new apartment, it was always cold for her; She is thrilled. Mrs. S. is an allergic person: "Since I live in a ThermoShield apartment, I feel better. When you enter into such an apartment, you notice the difference of ThermoShield to color."
