An energy audit is an inspection and analysis of energy flows in a building with the objective of understanding the energy efficiency home or building being audited.

Condition monitoring (colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance.

Predictive maintenance (PdM) is a type of condition-based maintenance that monitors the condition of assets through sensor devices. These sensor devices supply data in real-time, which is then used to predict when the asset will require maintenance and thus, prevent equipment failure.

Artificial intelligence (AI) is the ability of a computer or a robot controlled by a computer to do tasks that are usually done by humans because they require human intelligence and discernment.
