The simple presence of airborne fungal spores or fragments indoors is not a major cause for concern, unless
The species and rank order of concentration is significantly dissimilar with outdoor samples Potential “high-risk” fungal species were identified Fungi will grow until sources of moisture or nutrients are removed Effective remediation requires both cleaning and moisture control.

Indoor Air Quality as a Public Health Concern
Occupational hazards associated with indoor air quality are a recent phenomenon. Energy-conserving features often include windows that cannot open and thermostat controls that are not adjustable or accessible to building occupants. “Modern” buildings often are self-contained environments with temperature, humidity and airflow being controlled by one or more air-handling units. Sick-building syndrome and tight-building syndrome.

INDOOR AIR QUALITY
Building design and building management professionals have become more aware of the indoor air quality concerns of owners and occupants. RESULT: changes to improve indoor air quality and climate. HOW: changes in building designs; improvements in site planning/design; ventilation systems; limit of chemical contamination of air during construction and occupancy of buildings

“Maintain to Sustain”
Indoor Air Quality as a Public Health Concern
Energy conservation = construction of “air-tight” buildings. Heating, cooling, filtering and delivery of air requires consumption of energy. Poorly designed or improperly maintained HVAC systems cost more money to operate. Indoor air quality or lack of it is typically associated with the “air” and the HVAC system.

EFFECTS OF INDOOR POLLUTION Business Humans • Occupants Lost * Fatigues • Insurance Costs * Headaches • Sale/Rent Loss * Irritations • Productivity Losses * Nausea and
Dizziness • Energy Costs * Difficulty in
Breathing • Maintenance Costs * Sickness – H1N1 • Renovation Schedules • Workers Compensation

“Maintain to Sustain”
HVAC systems and the “link” with IAQ:
There is NO direct correlation between indoor air quality test and cleanliness of HVAC Systems The results of the air quality test was fine, therefore, the duct system is clean – NO! The air quality test does not dictate interior conditions of HVAC systems nor does it determine cleanliness of systems components
