- PublikationHybrid ventilation in residential and office buildings(IOP Publishing, 2023) Hoffmann, Caroline; Hauri, Claudia; Primas, Alex; Dorer, Viktor; Huber, Heinrich [in: Journal of Physics. Conference Series]This project is focused on hybrid ventilation systems, a combination of natural and mechanical ventilation in residential and office buildings. Especially in dwellings hybrid ventilation systems are quite common. For instance, this can be the frequently occurring combination of exhaust fans in bathroom and toilet and / or a range hood in the kitchen with window ventilation in the other rooms. Currently, these systems are part of the planning reality, however, there are neither planning aids nor focused building standards available. A recently completed research project documents the state of the scientific knowledge, identifies most common planning challenges, and thus provides the basis for future planning aids for hybrid ventilation. This paper sets out to define the term "hybrid ventilation", presents the most common hybrid ventilation systems in Switzerland and gives planning guidelines for current components of hybrid ventilation systems.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationPassive window ventilation openings in every-day use(Elsevier, 28.08.2021) Hoffmann, Caroline; Geissler, Achim; Hauri, Claudia; Huber, Heinrich [in: Building and Environment]The integration of passive window ventilation openings (PWVO, small air inlets integrated in the window frame) with additional exhaust fans in the kitchen and bathroom(s) can ensure a user-independent basic air change rate in dwellings. The project reported on herein is focused on how well buildings with PWVO work in real life.01A - Beitrag in wissenschaftlicher Zeitschrift
- PublikationConversion of unheated basements and the conditioning of their indoor climate(IOP Publishing, 2019) Hoffmann, Caroline; Geissler, Achim; Huber, Heinrich; Hauri, Claudia [in: Journal of Physics: Conference Series]This paper deals with unheated basements in existing buildings. Due to soaring housing prices these rooms may be increasingly used for the storage of sensitive goods and temporarily for leisure activities. In order to keep these rooms free of mould various technical solutions are available. However, it is unclear whether they prevent mould growth and how high their energy demand is. This question is explored by simulating an unheated basement in an uninsulated, a renovated and a newly built building. The paper considers and evalueates four different operation modes for the basement.01A - Beitrag in wissenschaftlicher Zeitschrift
