    Conversion of unheated basements and the conditioning of their indoor climate
    (IOP Publishing, 2019) Hoffmann, Caroline; Geissler, Achim; Huber, Heinrich; Hauri, Claudia
    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.

    Passive window ventilation openings in every-day use
    (Advanced Building Skins, 10/2019) Hoffmann, Caroline; Geissler, Achim; Huber, Heinrich; Hauri, Claudia
    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.

    Fensterlüfter in Wohngebäuden (Sanierung und Neubau) - Die Sichtweise der Nutzer
    (Brenet, 07.09.2018) Hoffmann, Caroline; Primas, Alexander; Geissler, Achim; Huber, Heinrich
    In diesem Paper geht es um passive Fensterlüfter (ohne Ventilator) im Zusammenhang mit einer Abluftanalge in bereits errichteten Gebäuden. Die Veröffentlichung konzentriert sich auf die Auswertung von Gebäudebegehungen und Nutzerbefragungen (280 Nutzer in 28 Gebäuden).

    Passive window ventilation openings for building refurbishment
    (Advanced Building Skins, 10.10.2016) Hoffmann, Caroline; Geissler, Achim; Huber, Heinrich
    A thorough building refurbishment generally includes window replacement and thermal insulation of the opaque building envelope. However, quite often only a window replacement is done and the building envelope is left uninsulated. This could lead to mould problems, because of the reduced air change. A possible solution can be the integration of passive window ventilation openings (PWVO). This paper deals with two questions: Firstly, can PWVO guarantee the necessary ventilation rate to avoid moisture damage? Secondly, how do PWVO compare to a ventilation system with heat recovery in terms of heating demand?
