The aim is to increase the use of high-quality ventilation systems in large-volume residential buildings. The aim of this project is to investigate how central or semi-centralised comfort ventilation systems in multi-storey residential buildings can be optimised, i.e. with simplified distribution, installation, control and operation, as well as more prefabricated components, and how electricity consumption can be reduced.
Simplified ("low tech" - comfort ventilation) or optimised innovative solutions for central or semi-central ventilation systems are to be developed in the interests of high user quality and improved energy efficiency.
Central and semi-central ventilation systems in residential buildings have potential for optimisation. Improvements should be sought above all in terms of their contribution to the overall energy balance (reduction of HWB vs. electricity consumption), their economic use and their ease of use for users.
An important question here is whether and how centralised or semi-centralised ventilation systems can be implemented more cost-effectively in multi-storey residential buildings in order to convince more housing developers and private individuals to use them. Ventilation systems in residential buildings are still not installed for cost reasons or are designed in an inadequate minimum version (exhaust air system), which does not fulfil the requirements for energy efficiency and comfort.
After the first "wave" of their use in residential buildings, ventilation systems must be optimised (in the sense of "purification", energy and resource efficiency), including in operation. The design and system technology must be simplified to such an extent that the implementation is less prone to errors and a high level of user comfort is guaranteed.
