This book focuses on guidelines for reducing the energy consumption in warehousing processes. It presents a model of formal assessment for energy consumption in the context of storage-system logistics, as well as a computational model consisting of three sub-models: energy consumption models for forklifts and stacker cranes, respectively, and an energy intensity model for roller conveyors. The concept model is based on the assumption that the unit load is received at a zero-energy warehouse. Subsequent handling, transport and storage processes, in which the unit load is moved vertically and horizontally through the system, equate to changes in energy intensity within the logistics warehouse management system. Energy recovery based on the handling equipment used can be collected in batteries. The evaluation method takes into account the intensity of the energy supplied to the logistics system and reduces the storage of the recovered energy - this figure represents the energy needed to pass through the logistics unit load storage system, and can be expressed in an energy intensity map.

This book explores the philosophical understanding of the “energy consumption” in warehousing process that can be found in the literature. It presents known technical solutions that, if they are used in cold storage rooms, can effectively reduce energy consumption: through lower power consumption and/or energy recovery, such as the use of photovoltaic panels. The final part of the book explores the problems discussed on the basis of a concrete example – a project involving energy recovery in a refrigerated warehouse.This publication also describes the design of refrigerated warehouses, taking into account their energy intensity. In the case of logistic warehousing systems, the pallets in warehouses can offer a source of energy – namely of the potential energy stored in the loads on the shelves. Given that today’s construction warehouses have heights on the order of several tens of meters, that energy can be considerable. In the case of refrigerated warehouses and cold storage facilities, it is necessary to monitor the stored goods in order to maintain a constant freezing temperature, in keeping with the requirements of the HACCP system. Inevitably, this calls for constant cooling of the air inside the warehouse, and thus produces a fixed, high and constant level of energy usage. And, just as in any other context, it becomes important to identify methods for reducing energy consumption.
