Company Y, a world leader in software applications has its corporate offices in southern India, we carried out IAQ sampling & testing at one of their premises.
Major IAQ parameters like SO2, Formaldehyde & Ammonia exceeded the permissible limits in most of the sampling locations.
The source of these emissions was associated to the interior wood work/carpets & interior cleaning disinfectants used. Outdoor air emissions from a parking lot just behind the building also contributed to this. This scenario is exacerbated if sufficient air circulation levels are not maintained.
The mitigation measures suggested were to
1) redesign their HVAC system without leakages so as to limit contaminants from outdoor sources
2) appropriate selection of materials, finishes and furnishings
3) proper cleaning and maintenance procedures
