Energy performance and indoor air quality in modern buildings in Greenland: Case study Apisseq

    Research output: Contribution to journalJournal articleResearchpeer-review


    A new dormitory for engineering students "Apisseq" was built in Sisimiut, Greenland in 2010. Its purpose is not only to provide accommodation for students, but thanks to its complex monitoring system, it enables researchers to evaluate the building's energy performance and indoor air quality. Some of the installed technologies are not commonly used in the current Greenlandic building stock. Therefore, evaluation of their performance under local conditions is essential for further use and development. The first year of operation has disclosed some errors made during the design process and construction phase, which have negative effects on the energy performance and indoor air quality. The heat demand in 2011 was 26.5% higher than expected. One of the main causes of the extra heat demand is the fact that the ventilation system was over-dimensioned, and although it is running on the lowest fan power it maintains 1.1 ACH in the building. Reduction of the airflows and better frost protection of the heat exchangers are important issues to be dealt with in order to decrease the heat demand. This article describes the building and how it is evaluated after the first year of operation, and it explains some of the revealed problems.
