Alternative 2: Controlled room Ventilation

The ideal solution for modern buildings is the controlled home ventilation with heat recovery. 
The installation of a controlled room ventilation system with heat recovery results in the potential for great savings. Controlled ventilation achieves similar high energy-saving potentials as solar technology and optimization measures at system technologies (generator, storage and distribution within the thermal envelope, utilisation of condensing technology). Therefore, the integral planning of buildings, ventilation systems and other housing technologies is an essential requirement for low investment costs, high primary energy savings and economical operations.
