Energy Audit

Abstract

This Energy Audit Course Handbook provides a comprehensive and structured framework for understanding and implementing energy audit processes, aligning with both international standards and specific national regulations in Algeria. It systematically guides the reader from fundamental energy concepts through the entire audit lifecycle—from preparation and on-site assessment to detailed analysis, reporting, and economic evaluation. The handbook emphasizes that energy auditing is not merely a technical exercise but a crucial management tool for enhancing profitability, competitiveness, and environmental stewardship. By adopting the methodologies outlined—such as establishing energy balances, utilizing Sankey diagrams, calculating key performance indicators (KPIs), and applying both analytical and empirical evaluation methods—organizations can transition from simple energy monitoring to active energy management. Furthermore, the document underscores the importance of economic feasibility and strategic prioritization, providing clear guidelines for assessing project viability based on return on investment (ROI), payback period, and risk. It also introduces modern approaches like outsourcing and Energy Performance Contracts (EPCs), highlighting the evolving role of Energy Service Companies (ESCOs) in the energy efficiency landscape. In the context of rising energy costs and regulatory pressures, this handbook serves as an essential resource for future engineers and practitioners. It equips them with the necessary skills to identify significant energy-saving opportunities, propose cost-effective measures, and contribute to a sustainable energy future, thereby fostering a lasting culture of energy efficiency within industrial and tertiary sectors.
