Sammanfattning: The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. Calorimetry is a general, but sensitive method that can continuously monitor biological processes as a function of environmental conditions. In this report, three different studies are presented: (1) A calorespirometric device was developed and used to study the energetics and gas exchange of one rot fungus and two mould fungi. (2) Calorimetry was correlated with the quantification of ergosterol, an established method in fungal research. It is shown that there is correlation between these two methods. (3) Calorimetry combined with equipment for humidity and temperature modification makes it possible to measure fungal activity at different temperature and humidity levels.
