Describes the investigation in 1994 of a suspected case of sick building syndrome at a communications centre. The building's central HVAC systems had a poor record of maintenance, and there had been continual structural modifications to the building. Inspection revealed the presence of fungal growth in the HVAC system. Remediation included employing a dedicated mechanic to implement a preventive maintenance programme. A significant drop in fungal concentrations was revealed as a result.
In the framework of the Flemish “Kantoor 2000” research project, the BBRI invited a Swedish inspector to apply the Boverket-OVK procedure for checking the ventilation installations in three Belgian buildings. This experience was most illustrative for the actual status of ventilation systems in Belgium. The procedure being very simple to apply was still very effective and able to detect most problems with ventilation installations encountered in these buildings. To control the quality of ventilation systems, three aspects of the building process are important:
