What public health risk must be balanced with water efficiency and chemical usage in every water treatment program?

  1. Botulism
  2. Mold growth
  3. Iron poisoning
  4. Legionella outbreak

Answer(s): D

Explanation:

Legionella outbreak is a significant public health risk that must be balanced with water efficiency and chemical usage in every water treatment program. Legionella bacteria can grow in water systems, particularly in warm, stagnant water. If not properly managed, it can lead to Legionnaires' disease, a severe form of pneumonia. Therefore, while striving for water efficiency and minimizing chemical usage, it's crucial to ensure that the conditions do not favor the growth of Legionella.

When conducting the Indoor Environmental Quality Credit, Occupant Comfort Survey what is the minimum percentage of building occupants that must respond?

  1. 10%
  2. 20%
  3. 30%
  4. 40%

Answer(s): C

Explanation:

The Indoor Environmental Quality Credit, Occupant Comfort Survey is a tool used to assess the performance and success of the design of a space. It gathers accurate and reliable feedback from the building occupants. In a sample survey, approximately 33% of the total building occupants responded1. This suggests that a minimum of 30% of building occupants must respond to the survey.
