Classifying Software Energy Efficiency
summary
ISO 5055-3 and a derived Digital Energy Score (DES) are used to classify software energy efficiency into six taxonomy classes, based on a benchmark of 3,200 applications. The talk presents real measurements, describes remediation work that typically takes 30–40 person-days, and reports experimental results: up to 40% portfolio-level reductions (estimated €600 million annual savings), average DES reductions of 14%, and measurable impacts on OPEX, cloud consumption, and response times.
