Correct
Q: When using a hydronic system instead of an air-based system, how much extra floor space might the building owner get from space efficiency gains?
A: Can be as high as 5%, because of the significantly improved space performance
Correct
Q: In a cooling system, a large body or surface with a lower temperature than the other surfaces in a room will…
A: …receive more radiation than it emits
Correct
Q: What characterises hydronic systems for heating or cooling?
A: Lower energy distribution costs and improved space efficiency
Correct
Q: How much more power does a forced air system use for the distribution of air than a hydronic system?
A: As much as 10 times more power may be required by air-based systems
Correct
Q: Water’s heat capacity is how many times greater than that of air?
A: 4.2
Correct
Q: What does the superior energy capacity of water mean?
A: Hydronic systems consume much less energy for energy transportation than forced air systems
