Which of the following is a radiant temperature system benefit related to air quality?

• A. Saved floor space
• B. Lower dust transportation
• C. Increased thermal comfort
• D. Reduced energy consumption

Answer: (B)

Radiant temperature systems heat or cool surfaces rather than moving air. Because they rely less on air movement to distribute heat, there are fewer convection currents in the space. Dust and particulates travel mainly with those air currents, so when convection is reduced, dust transport declines, improving indoor air quality. The other options don’t directly address air quality: saved floor space relates to layout, increased thermal comfort is a general benefit but not specifically air quality, and reduced energy consumption concerns efficiency rather than air quality.
