Damage to buildings seen in Denmark tends with some delay to turn up in Greenland. This makes it relevant to study buildings with moisture-related problems in Denmark and how they are dealt with in the Danish Building Regulations to prevent the problems from being copied in Greenland. As the requirements concerning moisture control are function-based, the construction client and the authorities are entrusted with interpreting requirements in a specific case, which caused the introduction of a guideline based on humidity risk classes. This paper presents the Danish requirements and guideline and gives examples of moisture-related problems in buildings in Greenland. Requirements and guidelines are needed in Greenland in order to deal with moisture in the construction phase, but as the conditions for constructing houses and the way that houses are used in Greenland are different from Denmark, an adaptation to the specific conditions in Greenland is needed.
