Our Process of Work

Establishing the Scope of the Audit: Define the objectives, areas of focus, and boundaries for the energy audit, ensuring alignment with organizational goals and energy-saving expectations.

Study the Energy Consumption and Production History: Review historical energy data and plant production records to understand usage trends and establish a baseline for the audit.

Discussion on Plant Practices and Usage Patterns: Conduct discussions with key personnel to gather insights into energy usage practices, operating schedules, and the overall energy management approach.

Onsite Data Collection: Gather real-time data on various parameters such as temperature, equipment dimensions, and flue gas temperature to support analysis.

Onsite Study of Processes and Critical Parameters: Analyze the operational processes and identify critical parameters influencing energy consumption, such as equipment efficiency and maintenance practices.

Collection of Standard Data: Collect all relevant standard data and guidelines necessary for accurate calculations and assessments during the audit.

Calculation of Losses and Appliance Performance: Perform calculations to determine energy losses and evaluate the performance of key appliances or systems, benchmarking them against best practices.

Identification of Improvement Opportunities: Identify potential energy-saving opportunities based on the analysis of data, and calculate the potential impact of recommended improvements.

Draft Report Submission: Prepare and submit a draft audit report, detailing findings, observations, and suggested energy- saving measures for review and feedback.

Feedback and Final Report Submission: Incorporate feedback into the final report, providing a comprehensive analysis and actionable recommendations to enhance energy efficiency.
