Ventilation with Heat Recovery - Optimal Air Quality for Airtight Buildings

Heat Recovery Ventilation Systems (MVHR) for domestic applications are a highly controversial topic, partly due to some misconceptions and negative experiences with cheap or wrongly installed systems. However MVHR systems have proven to be very successful in a variety of applications and appear to be one of the integral parts of energy efficiency

The seminar will not only show MVHR systems in practice within the show Passive House, but also show lots of case studies, interesting background and technical information, legislation, grants and points to be aware for installers and specifiers.

Helen's Catering Service will as usual provide an excellent culinary experience throughout the day.
