1381 Sample Retrofits

This section provides the equations to calculate savings from several different types of retrofits. For each type of retrofit, the calculations shown are based on average conditions and costs, which vary from location to location. For example, annual air conditioning hours will vary from building to building and from state to state. The energy costs used in the following examples were based on $10/kW-month and $.05/kWh. In most industrial settings, demand is also billed. In the following examples demand savings would likely occur in all except for examples # 4 and # 6. To accurately estimate the cost and savings from these types of retrofits, simply insert local values into the equations.
