Chilled water plants tend to be one of the most energy intensive areas of a commercial building. These plants can range from fairly basic to very complicated. Despite the importance of these plants for efficient building operations, we find that many plants are operated manually, and even those that are automated often are not operating at peak efficiency.
The key to chiller plant optimization is to remember that the meter is on the plant, not the chiller. This means looking for ways to meet the building loads reliably, and using as little energy as possible.
