Abstract [en]

When retrofitting culturally valuable buildings for improved energy performance we are faced with complications on top of those of modern ones, while failure in dealing with these complications may lead to loss of irreplaceable values. Thus we need trustworthy tools and methods that can provide us with the knowledge we need to create the appropriate retrofittings, minimizing energy use while ensuring preservation of the building and its interiors and comfort for the users. Simulations that render such knowledge are therefore important for the keeping of cultural heritage. This study looks into whether a dynamic simulation of the thermal exergy aspect can supply information that contributes in the assessment of different retrofitting strategies, by making such a simulation of a 13th century church equipped with an electrical IR-heating. The conclusion is that the dynamic exergy simulation does provide the desired information, in this case proving the IR-heating defendable exergy-wise.
