We develop and evaluate comfort oriented and energy efficient ventilation concepts for residential and office buildings. Our focus here is on decentralized ventilation solutions, which are particularly important in the context of the renovation and refurbishment of existing buildings.
For this purpose, air quality, air temperature and air humidity as well as their spatial distribution must be combined with efficient heat recovery concepts and suitable flow control. Energetic aspects are considered as well as the evaluation of indoor air quality with regard to comfort and user behavior.
Based on simulations and experimental characterization, we evaluate the energy demand and the indoor air quality on different scales. This enables us to develop and analyze equipment concepts or subcomponents such as distribution systems or new types of heat exchangers.
