Course Overview

Auditing for energy purchases, use, conversion, and waste is the first step in managing your energy consumption. For maximum effectiveness, it is essential to focus on the essentials. This is best done through the Pareto Principle (80% of the effect is caused by 20% of the factors). Energy Audit, takes a broad, comprehensive approach, then progressively zooms in on the specific issues and opportunities that deserve further investigation. The Energy Audit report can be used as the starting point for Feasibility Studies, Energy Management Plans, Retrofitting Existing Systems, and Design of new Energy Efficient Processes. 

With each Energy Audit, you get a detailed report on your current situation, and recommendations for more detailed study. Typical costs for an Energy Audit range from $500 (small, partial audits) to 20,000 for comprehensive studies on large buildings or industrial processes. Typical audits are $3,000 to 5,000 for 80% of the initial Energy Audits done. In this short course emphasize is directed towards energy auditing in multistage desalination systems. The attendees will have the opportunity to be exposed to the recent developments in operation and maintenance technology in this area Desalination technologies are overviewed Workshops on MSF system energy calculations are presented. Full and part load performance calculations are illustrated in connection with control systems Operation and maintenance of MSF are presented. Full and Part Load Operations are illustrated in connection with Control Systems in MSF Desalination Plant.
