Indoor air quality (IAQ) is a key component of employee productivity. IAQ describes one or all of several parameters (see side boxes for more detail):
Comfort index (temperature, relative humidity, air ventilation and exchange);
Moulds and other fungi;
Gases (carbon dioxide, carbon monoxide, NOx);
Volatile organic compounds (VOC’s); and.
Particulate matter (respirable and particulate).
Poor air quality can lead to employee fatigue and extended loss of time through sickness or disability. By monitoring and advising a building owner or operator, OCL Group, can work with a Client to provide an optimum working environment.
OCL Group has conducted indoor air quality investigations since 1982. Our project experience has included all types of buildings: hospitals, schools, office buildings, commercial spaces, call centres, court facilities and residences. We combine a broad range of skills and expertise to advise the Client on the indoor air as a system not just providing measurements. We can also work with employees and Joint Occupational Health & Safety Committees to explain work programs and results of investigations.
Please refer to the attached PDF files for some examples of recent projects.
