The report from the Energy Efficiency Observatory in Banking, produced by ABI Lab in November 2011, examines technologies and measures to improve energy efficiency in bank buildings. It includes analyses of energy consumption, the adoption of green ICT, opportunities offered by energy efficiency certificates, and cogeneration. The document highlights how banks are becoming more attentive to consumption management, with a growing interest in solutions that enhance energy efficiency, especially regarding lighting and the use of ICT. Benchmarking methodologies and consumption analysis results are also presented. The studies emphasize the need for collaboration among different business functions to maximize the benefits of green initiatives.
