What factor must be considered when planning load calculations for buildings with mixed use?

When planning load calculations for buildings that accommodate mixed use, the peak load requirements of each usage type are crucial to consider. Each area within a building may have different purposes—such as residential, commercial, or retail—which in turn leads to varying peak electrical demands.

Understanding these peak loads is essential because it helps ensure that the electrical system can handle the maximum demand without overloading. For instance, a retail space may have high energy demand during specific hours of operation, while residential areas might exhibit peak usage during the evening hours. By taking these variations into account, planners can design an electrical system that provides sufficient capacity and avoids potential power outages or equipment failures.

Considering the peak loads facilitates the design of feeders and service equipment that are adequately sized and compliant with relevant electrical codes, ensuring both safety and efficiency in energy usage. Proper planning of these factors directly contributes to the functionality and safety of the building as a whole.
