- Warmth recovery
It refers to the continuing use of the energy bound in the waste air of ventilation plants. This is done with the help of crossed heat changers or warmth pumps.
- Warmth protection calculation
It is done according to the standards set by the "EnEV" for buildings in construction or renovation. It gives information about the expected energy demand and serves for the measuring of warmth supplying plants and the projection of outside components. On this basis the energy /warmth demand ID is issued.
- Warmth loss
It takes great influence on the energy demand of buildings in Central and Northern Europe. The insulation features of the building shell comes first in optimizing the warmth demand This transmission loss is defined by the temperature difference between inside and outside and by the U-value of the component Another factor is ventilation loss, which can differ due to utilization behavior and kind of ventilation. Construction with loss minimization should therefore be more important than money orientated construction.
