Which abbreviation stands for Indoor Environmental Quality?

• A. LT
• B. WE
• C. ID
• D. EQ

Answer: (D)

The main idea here is recognizing how LEED/USGBC materials label different categories with abbreviations. In this context, Indoor Environmental Quality is represented by the abbreviation EQ. Indoor Environmental Quality covers the conditions inside a building that affect occupant health and comfort, including air quality, thermal comfort, daylight and lighting quality, acoustics, and emissions from indoor materials. That’s why EQ is the best fit for Indoor Environmental Quality.

Other abbreviations in the set correspond to different topics—for example, one is commonly used for Lighting and another for Water Efficiency—so they don’t denote Indoor Environmental Quality.
