Conventional energy benchmarking and introduction to benchmark energy factor (BEF) for industrial systems and processes
|Publication Date:||1 January 2017|
This Publication presents the conventional methodologies used for benchmarking today. The different types of benchmarking practices and their evolution are explained. The next generation of benchmarking called, "ideal state benchmarking" is introduced briefly. Government-led industry programs in the US and Canada are driving benchmarking activities through rating systems and certifications.
This Publication focuses on energy performance benchmarking for industrial systems and processes (ISP). Conventional energy performance indicators (EnPI) and energy use intensities (EUI) are briefly described and the importance of considering the influence of variable independent parameters on what is considered to be best available practice. There are several factors that limit the reliability and accuracy of conventional benchmarks based on conventional methods. The challenges and limitations are presented along with case studies.
A new energy performance benchmarking concept called, "ideal state benchmarking" is briefly introduced with a high level outline of potential benefits. A case study is presented in Annex A. Basic terms are defined such as the "ideal energy", "essential energy", "energy-at-risk" and the "benchmark energy factor" (BEF).
Note: The new ideas and concepts presented in this Publication have been previously researched and largely explained in two IEEE papers, "Novel Method of Benchmarking Energetic Efficiency of Industrial Systems", and "Benchmarking Industrial Systems Using Energy at Risk and Benchmark Energy Factor Concepts".
