222:. The diversity factor provides a correction factor to use, resulting in a lower total power load for the ten AC units. If the energy balance done for this facility comes out within reason, but the demand balance shows far too much power for the peak load, then one can use the diversity factor to bring the power into line with the facility's true peak load. The diversity factor does not affect the energy; it only affects the power.

In the heat networks design the coincidence factor is often called a diversity factor (CIBSE guidance, DS 439). So, in the context of hot water systems the diversity factor is always less than 1. For space heating, for more than 40 dwellings the factor levels out to approximately 0.62. For domestic

or "diversity." For example, one might have ten air conditioning units that are 20 tons each at a facility with an average full load equivalent operating hours of 2000 hours per year. However, since the units are each thermostatically controlled, it is not known exactly when each unit turns on. If

defines the coincidence and simultaneity factors identically, with the diversity factor being their reciprocal. Since the only change in definition is to take the inverse, all one needs to know is if the factor is greater than or less than one.

Diversity factor is commonly used for a number of engineering-related topics. One such instance is when completing a coordination study for a system. This diversity factor is used to estimate the load of a particular node in the system.
