All of the factors that influence as we live and work in buildings are referred to as:

A. indoor air quality
B. indoor environmental quality
C. quality management control
D. Multiple quality sensitivity

Answer 13

B. Indoor environmental quality

Question 14

Describe some of the relationships between HVAC maintenance and IAQ/IEQ issues.

Answer 14

Standing water will accumulate if the drain pan is not properly designed and maintained, creating a microbial habitat. Proper sloping and frequent cleaning of the drain pans is essential to good indoor air quality.

On humidification and dehumidification equipment what services should be properly drained and periodically treated to prevent microbial growth. Duct lining should not be allowed to become moist from water spray

Clean surfaces on outdoor air damper‘s to remove dust buildup

Use air filters to remove particles from the airstream

Air Plenum’s need to be kept clean and nothing should be exhausted into the air Plenum

Keep sources of air pollution away from fresh air intakes

A. Sick building syndrome
B. Multiple chemical sensitivity
C. Building related illness
D. Environmental hypersensitivity

Answer 15

C. Building related illness

Question 16

How can managers control mold in a building?

Answer 16

Fix leaks quickly

Watch for condensation, water spots, standing water

Reduce the humidity in the air (less than 60%)

Increase ventilation

Maintain HVAC systems

Question 17

Employee discomfort with the building temperature is leading to complaints. Sheila believes the windows are drafty in Howard is always cold. The managerial team has found the best solution to this problem to be:

A. issue portable heaters to each employee

Full building air flushing before occupancy to ensure the systems are clean

Building automation systems that manage the balance of indoor and outdoor air

Employing less toxic indoor and outdoor pest control procedures

Use of fewer and less toxic landscaping chemicals and fertilizer
