Temperature and humidity are two important parameters that affect thermal comfort, which in turn may cause potential problems to your indoor air quality.

Relative humidity levels below 25% are associated with increased discomfort and drying of the mucous membranes and skin. On the other end of the spectrum, high humidity levels (>60%) may result in condensation within the building structure and on interior or exterior surfaces. This may lead to the subsequent development of mold.

ASHRAE Standard 55-2009, Thermal Environmental Conditions for Human Occupancy, presents guidelines that are intended to achieve thermal conditions that at least 80% of the occupants would find acceptable or comfortable. ASHRAE specifies a range between 25% and 60% as ideal.

Managing the relationship between temperature and humidity will control thermal comfort within the space and reduce the potential for the presence of biological contaminants including mold. Finding the right balance between the two is important. Mold contamination can cause health issues including respiratory problems, allergies, eye, nose and throat irritations. Indoor mold contamination in your home or workplace may be undetected until symptoms appear.

AirMD’s team of environmental consultants are equipped to assess whether or not your temperature and humidity levels are in harmony with each other for a healthier indoor quality environment.

On site, AirMD consultants will:

Determine if moisture is present in building materials;

Check for any evidence of high or low temperatures;

Check for local sources of heating or cooling;

Ensure that there is a balanced air distribution network;

Look for any obstruction of air circulation, among other key pieces of evidence.
