The increasing level of office based activity and the requirement to minimize energy usage is putting greater demands on building Heating, Ventilation and Air Conditioning  (HVAC) systems and on building owners and managers. Tighter buildings are now  being constructed to reduce the infiltration of outside air through building leakage. The amount of fresh air introduced through the air conditioning system is also reduced. In addition, there is now recognition of the health effects associated with passive smoking and the problems associated with off-gassing from carpets and modern synthetic construction materials.
EnviroSafe Australia Pty Ltd. offers a comprehensive building health management service to assist clients to effectively manage the indoor environment and ensure compliance with their legislative obligations. Our aim is to ensure that potential health risks associated with the building environment are suitably managed and comfort criteria optimised. This is achieved by consideration of the three principal aspects affecting air quality and comfort: Air Quality Testing, Building Ventilation Assessment and Cooling Tower Inspection.
Air Quality Testing
State of the art technology and instrumentation is used to measure a broad range of air quality parameters in the building environment. Such key parameters include:
  • Temperature and humidity
  • Carbon dioxide
  • carbon monoxide
  • Total suspended particulates
  • Formaldehyde
  • Volatile organic compounds (VOC's)
  • Airbourne fungi/mould/bacteria
  • Asbestos fibres
Building Ventilation System Evaluations
An evaluation of the building's ventilation system is performed taking into consideration location of fresh air intakes in relation to exhausts and sources of  pollution, air supply rates, operating schedules, maintenance etc. Critical components of the building ventilation systems and plant are inspected to ensure that design and maintenance programmes conform with the recognised building alth services guidelines. Maintenance procedures are reviewed to the requirements of Australian Standard AS3666: Air-handling and Water Systems of Buildings - Microbial Control.
