Investigation of the indoor environment on the university campus in Luleå

Several investigations of the buildings in the university area of Luleå have been carried out as a result of staff staying in the premises reported health problems. Buildings erected in the 1970s have in many cases been found to have construction design faults that are expected to affect the indoor environment. Based on the results of the investigations carried out in other buildings, it has been decided to carry out all indoor environment investigations on all buildings in the university area of Luleå.

The University and Akademiska Hus have agreed that indoor environmental investigations will be carried out in all buildings in the university area of Luleå. Staff and students will be kept constantly informed about investigations and actions, including through this website .

Based on studies and measures already carried out, the different buildings in the picture above are given different colors, depending on whether there are deviations in the indoor environment. The deviations that exist and are expected to affect the indoor environment are followed up and rectified.

B, small D green light. No deviations

C-house, D-house, F-house, K-house red light. Deviation exists Investigation shows a number of structural technical deviations / damage.

The E-house, the A-house. Investigation is in place

The purpose of the indoor environment investigations is to identify risk factors relating to indoor environmental problems in the building and, based on these, make an assessment of the need for measures. Sampling is carried out which involves design interventions, moisture measurements and subjective assessments of walls, floors and ceilings. Scope and location of test points are decided in consultation with the operations and based on risks in the building design, reported indoor environmental problems, odor assessment in the residence zone and previous water leakage. Odor assessment is performed after the ventilation has been turned off during a weekend. Operations are continuously informed of any disruptions.

Indoor environmental investigations are complex since there are no limit values for eg. mold or emissions in non-industrial indoor environments, as well as the relationship between health and individual pollution or the overall level of pollution. According to the Public Health Authority, however, there is a known connection between moisture damage and experiences of inconvenience in the indoor environment and buildings must be designed in accordance with the National Board of Housing Regulations so that moisture does not cause damage, odor or microbial plant that can affect hygiene or health. Indoor environmental investigations are therefore based on identifying moisture-damaged materials.
