Challenges to national defence in contemporary geopolitical situation

The topic of energy use and energy consumption is currently largely dealt not only in the architecture and civil engineering but also in the military environment. The operating costs of military camps and facilities can be rising extremely quickly especially in hot climate conditions where the requirements for appropriately air-conditioned working places and other mission related areas are crucial for the uninterrupted command and control of any operation. The energy use and energy consumption must be considered already during the planning phase of the military facility and it must take into account as many limiting factors as possible. This is not a completely new problem and many different approaches to the solution are already here and ready to use, and one of them is a method or a system called energy audit that is an efficient tool for improving the energy use and consumption.
