Temperature in buildings - Designing Buildings WikiTemperature in buildings - Designing Buildings Wiki - Share your construction industry knowledge. Temperature is a measure of the average kinetic energy of molecules. This is important as the average temperature relates to the movement of molecules in a substance or material. A cup of boiling water will be hotter than the Atlantic Ocean but the latter will contain much more heat than the former.

The Approach Temperature Difference (ATD):

For maximum effectiveness, this temperature increase should be small, because it means that the condensing temperature below. However, higher flow rates required need more fans and/or pumps, which also consume energy. As always with cooling systems, a reasonable balance (i.e. the optimal design) must be found between conflicting requirements.
