Updated investigation C-house

Published: 12 November 2019

Landlord Akademiska hus has presented the result of the indoor environmental study of the C-building to the university. The investigation shows similar shortcomings that have already been identified in the D- and F-buildings.

Due to the indoor environment of the D- and F-buildings, the work to find alternative premises has already been started by the university. The university is now also considering revising the previous decision to rebuild the C-house to create method rooms. The university is looking for alternative premises in the short and long term.

– In connection with the planned internal information meeting on the C-house on November 18, we hope to be able to provide information on measures and alternative premises,  Veronika Sundström, says new university director at Luleå University of Technology.

Summary of the C-building report

After discovering building-related ill-health in other buildings in the university area of ​​Luleå, Akademiska Hus chooses to investigate if the same problem is found in other buildings. In agreement with Luleå University of Technology, all buildings within Akademiska Hus's property portfolio on Campus Luleå must undergo an examination to find any inconvenience. After the reviews of the D and F houses, the tour has come to the C house. The C- building also houses STUK (the students' restaurant / bar with Akademiska Hus as landlord) and STIL (Luleå's largest gym with the university as landlord).

The purpose of the investigation has been to determine risk factors for ill health in the indoor environment in the C-house, by conducting general investigations in all parts of the house through moisture indication, control of wind space and determination of design structure and current moisture status. The assessment of these risk factors is based on, among other things, that according to the Public Health Authority, there is a known connection between moisture damage and experiences of problems in the indoor environment and that moisture and mold damage should therefore always be addressed.
The investigation of the C-building has generally not shown that there is ongoing moisture damage in the C-house, however, effects of previously abnormal moisture effects have been found, which can cause the same type of health problems as ongoing moisture damage. No abnormal microbial odors have been found in the premises. The older moisture damage detected may have occurred from the time of construction of the building to the moisture impact that has occurred periodically over the years.
The concise answer is that ceilings, floors, joists and partitions in the C-house have no general faults / faults. Only local inconveniences occur. In contrast, the examination shows that the outer walls of floors 2, 3 and 4 generally show signs of moisture.

Prior to the report on the status of the entire C-house, corridor C100 was examined. This examination showed that the exterior wall construction towards the Rainbow Hall has a number of shortcomings - water has penetrated the wall above the window in the outer wall. Local damage to floors adjacent to the exterior wall was also found, probably caused by radiator leakage. Measures for the C100 corridor have been awaited until the investigation of the entire house has been carried out in order to enable possible coordination of measures and to reduce the disruption to the business.

All systems for ventilation have also been examined, mainly with focus on ventilation flows and air quality. The review shows that no general inconvenience to the ventilation in the C-house is generally workable with a few exceptions that can be improved.

Facts from previous studies of indoor environment:

Personnel at the university area in Luleå have for a long time reported experienced health problems linked to stay in the workplace, mainly in buildings D and F. Extensive investigations and measures have been carried out but the problems have remained. In 2018 and 2019, the D and F houses have been re-examined to get answers on how the building construction works from a moisture point of view. These investigations have shown that building D and F have extensive moisture-related damage that is considered to have a negative impact on the indoor environment.
