How’s your indoor air quality?
Ever had that feeling while sitting at your desk that a bit of 'shut-eye' would be welcomed if only possible and you find yourself asking … 'Why do I feel this way?'
The answer could be attributed partly to the air you are breathing.
HVAC systems are not only important in commercial and industrial premises for our thermal comfort, but also for indoor air quality (IAQ).
Air that is too warm, or is stale and stuffy can cause people to feel lethargic, especially in the afternoons, resulting in poor productivity and possible absenteeism. Your staff's health will benefit from good indoor air quality and so will your business.
Signs of poor indoor air could be:
- stale or unpleasant odours
- temperature is too warm
- dampness and mould
- airborne contaminants, including bacteria.
Moisture and dampness can exist inside buildings when humidity, lack of ventilation, or condensation are present. Lack of light can result from rooms with curtains or blinds drawn and little outside light entering the room.
Mould growing in indoor spaces has been found to affect people's health by:
- irritating skin, eyes, throat
- congesting the nose and sinuses
- coughing and breathing difficulties
- increasing the risk of lower respiratory illness.
The US Environmental Energy Technologies Division cites studies concluding that
The solution to
Maintaining and monitoring the HVAC system
An air conditioning system that has been correctly designed and is properly maintained will meet
- correct air volume for the room size and heat load in the room
- correct outside air ratio
- correct filter selection and maintenance
- ensuring your maintenance program meets not only your financial needs but also the legal requirements.
It is important to note that changes to the original area design of indoor premises can affect the air conditioning of a building. Have your HVAC maintenance provider involved in the proposed changes prior to implementation.
Keeping your indoor air clean and healthy
The hallmarks of good IAQ are that the air:
- flows to all areas of the building
- is mixed with fresh/outside air
- has O2 levels that maintain alertness in your workforce
- is maintained at a comfortable temperature
- is free of bacteria and airborne particulates.
A well-maintained HVAC system is
Critical Air will:
- conduct IAQ checks
- check for moisture,
mould anddirt in ventilation systems and clean the entire system
- replace filters in the system and
- provide comprehensive reports on the findings.
Good design and construction is the foundation for a healthy building and the HVAC system is all-important for indoor air quality.
The best HVAC systems are those that improve air quality and reduce the amount of energy used for ventilation.
