Rolf-Peter Strauss | Ventilation – simple and elegant!

This paper presents a semi-central residential ventilation system integrated into the façade around windows. Simple and visually subtle ventilation solutions can be implemented, even under difficult retrofitting conditions. The concept relies on an innovative enthalpy exchanger made of folded paper.

Bernhard Martin | A new ventilation concept for small dwelling units

A satisfactory ventilation solution for small Passive House residential units has been lacking on the market. With its installation location in an outside wall, connections for other rooms, and sensor-controlled demand management, the new freeAir 100 system from bluMartin can meet that need.

G. Rojas-Kopeinig | Cascade ventilation – air exchange efficiency in living rooms without separate supply air inlets and exhaust air outlets

CFD simulations and measurements were used to study whether and to what extent airflow between outlets can short circuit if the outlets lead to a common hallway. Planning tips for expanded cascade ventilation (without fresh air outlets in the living room) were derived from the investigation.
