Collecting and managing sustainability data for energy efficiency can be a challenging endeavor, especially if you have multiple sources, formats, and systems of data. To simplify and streamline the process, it is important to define your data requirements, assign roles and responsibilities, use appropriate tools and technologies, and establish quality control and assurance procedures. Specifically, you should determine what data is necessary to measure and report on your energy efficiency metrics such as energy types, units, conversion factors, scope, boundaries, and frequency. Additionally, assign clear roles and responsibilities for data collection, validation, analysis, and reporting with the necessary skills, resources, and authority. Moreover, use tools and technologies that can automate, integrate, and standardize your data collection and management such as sensors, meters, software, databases, and dashboards. Lastly, create quality control and assurance procedures to ensure that your data is accurate, complete, consistent, and reliable through data verification processes like auditing or feedback.
