- PublikationPassive window ventilation openings in every-day use(Advanced Building Skins, 10/2019) Hoffmann, Caroline; Geissler, Achim; Huber, Heinrich; Hauri, Claudia [in: 14th Conference on Advanced Building Skins]In Switzerland, 70 % of building refurbishments are realised in stages. When only a window replacement is done, the new airtight windows can lead to a reduced infiltration air exchange and subsequently there may be moisture issues, e.g. mould. The integration of passive window ventilation openings (PWVO) with additional exhaust fans in the kitchen and bathroom(s) can ensure a user-independent basic air change rate. PWVO can be defined as small air inlets integrated in or near the window frame. These inlets enable a basic air exchange due to the pressure difference between inside and outside. This project is focused on how well buildings with PWVO work in real life.04B - Beitrag Konferenzschrift
- 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
