The cost of heating argument

In today’s average existing buildings, approximately 20 litters of heating oil is consumed per year for each square meter of living space. In comparison, a thoroughly planned passive house uses less than 1,5 litters of heating oil per year for each square meter of living space, as far as the comparison with heating oil is appropriate, since passive houses are supplied foremost by ecological energy sources. For this purpose, Themessl uses geothermal heat pumps, which during the peak summer period, can even be used as simple cooling systems.

The superior technology

The special quality of the exterior shell and the intelligent interior air quality management system produces a level of thermal comfort, which is by far superior to the conventional buildings. The lack of draughts, constant operational temperatures and very low asymmetry of the radiant temperature are sensed in the new living comfort levels, which until recently had not been conceivable. Through a controlled intake/outtake ventilation system, a guaranteed fresh air supply and interior air quality is reached. Due to this, the management of the heating and ventilating systems will not become more complicated, but rather simplified. For connoisseurs and interested people, the technical achievable criteria of the Themessl Passive Houses is convincing.
