Total Equipment Energy Effectiveness (TEEE): A comprehensive model to manage energy in manufacturing

Abstract Energy efficiency brings considerable benefits to society and industry through reducing carbon footprint, helping to protect environment and improving energy security and sustainability. It saves money on fuel bills and boosts growth and creates jobs in the economy. The industry sector is a major contributor to energy consumption and related greenhouse gas (GHG) emissions. It has a lot of potential to further reduce energy use and greenhouse gas emissions. Total Equipment Energy Effectiveness (TEEE) addresses the current challenge of a distinct lack of a comprehensive model to embrace all potential aspects of equipment, manufacturing processes and energy features for measuring equipment energy efficiency. The model needs to be flexible enough to cater for the needs of every manufacturing firm. It can be used at equipment level, process level as well as the broader level of a factory. The model is a measure of how efficiently equipment consumes energy compared to its full potential and can be applied as a tool to improve energy efficiency. The comprehensiveness involved might be a potential obstacle to implement a total energy effectiveness method particularly in SMEs. However, the problem is tackled by a novel TEEE Methodology which simplifies its application even for small companies. TEEE makes the concept of equipment energy effectiveness clearer and more applicable and also makes communication more efficient and easier within manufacturing industry. It provides a sound perspective on improvement to sustainability and also can be used as a benchmark and tool to promote energy awareness in the factory.
