Ventilative cooling—i.e., the use of natural or mechanical ventilation strategies to cool indoor spaces—can be very effective to reduce the cooling energy demand in buildings, under summer or mid-season conditions.
This webinar is part of a broader series focusing on ventilative cooling in energy performance, within the context of compliance with building regulations in several countries.
In the first presentation, Prof. Dr. Servando Álvarez, from Grupo TERMOTECNIA at the Engineering School of University of Seville, Spain, will analyse the reasons why ventilative cooling is not trivial: if cooling potential by night ventilation is greater than cooling demand (even in hot climates like in southern Spain) why does a cooling demand remain? Prof. Álvarez will highlight the key challenges for ventilative cooling, and possible ways to promote its efficiency.
In the second presentation, Dipl. Ing. Johannes Schrade, from the Department of Energy Efficiency and Indoor Climate at the Fraunhofer Institute for Building Physics (IBP) in Germany, will present a study examining the influence of night ventilation on the cooling demand of typical residential buildings in Germany. Ing. Schrade will explain why increased night ventilation is a particularly cost-effective option to influence the indoor climate, so that comfortable conditions are viably ensured, keeping technical expenditure within reasonable bounds. The potential of night ventilation under German climate conditions will be examined for two exemplary cases, namely for a single-family home and a multi-family building.
