Energy-efficient renovation – heat recovery ventilation

Energy-efficient renovation is about more than new windows, insulation or a modern heating system.

Set in an everyday scenario, the film highlights the crucial role of controlled ventilation for indoor climate, moisture management and living comfort – especially in buildings with airtight envelopes.

Using a likeable protagonist, the film clearly explains the relationship between air exchange, humidity and energy loss. An animated sequence visualizes how a heat recovery ventilation system works: stale air is extracted, the heat it contains is retained within the system, and fresh, filtered air is preheated before being supplied back into the living space.

The film communicates the benefits of the solution in a clear and tangible way – from improved energy efficiency and better indoor air quality to a reduced risk of moisture-related damage. Particular emphasis is placed on the fact that the system can be easily retrofitted, making it ideal for the energy-efficient renovation of existing buildings.
