You're managing energy monitoring processes. How do you ensure data accuracy while streamlining operations?

Years of experience as an energy manager can show that as important as checking the data collection sensors is evaluating the quality of the equipment in the monitoring system acquisition process. The manager needs to be careful when purchasing sensors that meet all technical and legal requirements applicable to the business, in addition to appropriately sizing the measurement network so that the system allows the identification of possible energy leaks. Periodic verification and calibration of sensors also ensures data reliability.

To ensure data accuracy in energy monitoring while streamlining operations, implement a robust verification process for sensors. This involves regular cross-checks with reference sensors, using statistical methods to identify anomalies, and employing automated diagnostics to detect and correct errors in real-time. Additionally, maintain a comprehensive log of sensor performance and environmental conditions to track and address any deviations. By focusing on these verification techniques, you can enhance data reliability without relying solely on calibration, thus ensuring efficient and accurate energy monitoring. Calibration is only needed if the verification process could not yield a conclusive finding.

Automating data collection significantly reduces transcription errors by eliminating manual data entry, which is prone to human mistakes. By using sensors, IoT devices, and automated software, data is captured directly from the source and transferred to databases in real-time. This ensures higher accuracy and consistency, as the data flow is uninterrupted and less susceptible to errors. Additionally, automation streamlines the process, saving time and resources, and allows for immediate data analysis and reporting. Overall, automating data collection enhances reliability and efficiency, leading to better decision-making and operational performance.

To automate data collection, it is necessary to have a system that guarantees not only data reliability but also the ideal frequency for analysis. To ensure reliability, important points must be considered such as the measurement mesh, system parameterization, greater frequency detail - with the minimum possible time interval, in addition to the implementation of a data quality assessment routine in order to identify possible measurement failures or interference.

During the process of defining the monitoring system, it is very important to consider the choice of software that allows integration via API to receive and send data. When we talk about energy performance analysis, the energy factor for the development of energy KPIs is generally monitored through other software. When we define the system to be used and allow this integration, we can have performance analyzes in real time.

Conducting regular internal audits is crucial for identifying gaps in processes and ensuring continuous improvement. These audits systematically review operations, compliance, and performance metrics, uncovering inefficiencies, non-compliance issues, and areas for enhancement for the data collection process. By regularly assessing and documenting findings, organizations can proactively address weaknesses, implement corrective actions, and optimize workflows. This ongoing evaluation not only enhances operational efficiency but also fosters a culture of accountability and continuous improvement, ultimately leading to better overall performance and risk management.

To carry out energy audits, I have always liked to use the GEMBA Walk methodology - present in lean manufacturing practices. Walking around the places where things happen combined with data analysis from monitoring systems allows a real view of the operation reinforced with performance data.

I believe that as important as training the team is also enabling them to replicate this knowledge, thus, it is possible to create the development of knowledge sharing between team members at different levels of the organization.
