Climate Control in Cultural Heritage Buildings in Denmark

Conservation heating has been used for decades to control the RH in cultural heritage buildings. But if the building is not used for living or working, heating is not needed for human comfort. The chemical decay of organic materials depends mainly on temperature, so it is better for preservation to reduce heating. The air exchange rate is related to the design of the building envelope. With rising energyprices humidity control by dehumidification may be an attractive alternative. The potential for energyefficient RH control was examined for a generic building exposed to the monthly average outsidetemperature and RH in Denmark. The indoor temperature was allowed to follow the outside average,whereas the indoor RH was controlled to 40 % 50 % 60 % or 70 %. Dehumidificationwas implemented inthree different buildings: A recent museum store, a medieval church, and an 18thcentury countrymansion. The energy consumption depends on the RH set point, theair exchange rate and the source of liquid moisture to the building. The air exchange rate related to the design of the building envelope. Single glazed windows and doors are the most important sources ofleakage to buildings. Lack of maintenance may lead to poor performance of the dehumidifier and waste energy.
