60 Energy consumption in comparison Energy saving ventilation unit for the low energy house – ZEB EC ZEB EC Energy saving unit with power – ideal in houses or in multi storey buildings. Low energy and passive houses are setting new standards with reference to sealing and insulation of buildings. To fulfill the energy saving regulation (EnEV) ventilation units have to be used with highest efficiency in full and controlled operation. The consequence of the EnEV1) is a controlled ventilation with a minimum consumption of energy (at present < 25 W/100 m3/h, in future < 12 W/100 m3/h). The ZEB EC is already today better than the required limit set for the future regulations. The diagram shows clearly the energy saving of the ZEB EC in comparison to the ZEB 380 that is equipped with a conventional AC-motor. There is an annual energy saving of 150 kW/h2) using the ZEB EC. The increase of the efficiency is reached by using an electronically commutated EC-motor. 1) Energy saving regulation 2) With daily operation on Trickle ventilation, step 18 h General ventilation, step 2 14 h Top requirement, step 3 2 h Äpstat.

61 Air extract elements Roof terminations Central ventilation box ZEB.. Air intake elements Ventilation designed to achieve a comfortable room climate and the preservation of a healthy fabric of the building with extraction of humidity, smells and harmful substances as well as being draught free. The ZEB-system achieves this perfectly. It doesn't matter whether it is in houses, in apartments that are to be ventilated per storey with one central shaft (DIN 18017, Pt. 3) or in commercial applications. The solution is economical, efficient and quiet. ZEB 380 und ZEB EC an air extraction unit below...
