Resolution of sick building syndrome in a high-security facility.

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.

Effect of quality and maintenance of the ventilation to the indoor air quality.

The aim of this study was to find out the indoor air quality in the real estates of the state and what was the effect of ventilation to the indoor air quality in these buildings.

Specifying commissioning for HVAC systems


An engineering approach to ventilation system design.


Lessons learned from the application of the Swedish Boverket-OVK procedure in Belgium.

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:

Ventilation and IAQ for the hospitality industry.
