Table III.

Findings of the surveys

Structure/feature	Findings
Microbes	High concentrations of different bacteria, fungi and microbes have been detected in several air and material samples
Roof and skylights	Water leakages occurred several times from roof and skylights Failures in structures due to vandalism Construction errors
Walls	Indication of water damage and microbes in partition walls External walls not studied on a large scale Construction errors in external walls
Windows	Recurring water leakages from windows in two classrooms
Floor	High relative humidity in several areas of the base floor Unpleasant smell from the base floor Material emissions from glue on the concrete floor
Sewers	Smell from sewers Corrosion in some sewers Accumulation of debris and dents in rainwater drains
Ventilation and air pressure	Air flow in many rooms lower than planned High negative, 25-30 Pa, air pressure in some rooms compared to outdoors Blocked ventilating pipes
Indoor environment	Carbon dioxide levels in classrooms were reported to be generally at a normal level Temperatures in classrooms generally at a normal level Relative humidity has been occasionally slightly below normal level, relative humidity 20-30%, resulting in a feeling of dry air
Yard	Pooled water close to the building Plants growing close to the building Minor slanting of the yard away from the building No underdrain system
Other	Dust, poor standard of cleaning Cracks in joints of several structures, leaking structures
