CEP CLEAN ENERGY & PASSIVEHOUSE informed about current developments in the living air ventilation a pleasant indoor climate and hygienically safe room air quality are the basis for healthy living and relaxation-the. The CEP CLEAN ENERGY & PASSIVEHOUSE is devoted to the half in its fifth edition in particular the steady wake – send interest to the topic of ventilation and a focus on the controlled housing ventilation with heat recovery, which makes a significant contribution to the healthy climate in buildings. From 29 to 31 March 2012 around 300 exhibitors – including 30 alone in the field of housing ventilation – at the CEP offer a comprehensive market overview of the latest technological developments and their applications. Buildings to be built are to be so that the minimum air changes required for the purposes of health and heating is ensured”, calls for the current version of the energy saving regulation EnEV on the basis of the present loads of room air.

Renovated old buildings and new buildings which comply with the provisions of the “EnEV” and thus have a dense construction, however, only an inadequate air exchange takes place. You could reduce almost broken houses, construction experts warn. Housing ventilation systems are therefore an important component in the energy-related modernisation of buildings. Only, if the ventilation is controlled, the calculated energy gains can be realized in fact and hygienic needs to be air changed permanently in an energy efficient manner and without sacrificing comfort can be only with a ventilation system to ensure and control.
