You will be taught the fundamental principles of energy efficiency by way of looking for points of wastage, assessment of the cost of energy usage and benefits accruing from improved energy efficiency in the facility. Reference points are needed, so the workshop will also show you how to quickly and effectively perform an energy audit of your facility, demonstrating the use of installed instrumentation as well as measuring equipment deployed during the audit.

Once you have the correct information from the audit, you will be taught a simple method of cost analysis to help you make the right decisions for improvement, based on the principle of Rapid Return on Investment (RRI).

This will enable you to implement the optimum energy-efficient solution and thus to start saving money in some cases immediately, but in a worse case a typically short period of time (perhaps 3 to 12 months RRI).Previous participants have been delighted with the immediate and long term sustainable savings they have been able to make as a result of attending this workshop.

This course is designed to enable participants to:

• Establish an Energy Savings Strategy for your organisation
• Put together practical energy efficiency plans for your firm that will save money
• Use the energy savings toolkit and checklist from the course in your workplace
• Conduct a simple energy audit of your workplace and collect good data
• Read and interpret data from different types of measurement equipment
• Interpret and analyse case study data and relate this detail to your facility
• Improve employee working conditions and productivity with minimal outlay
• Assist in the reduction of greenhouse gases and improvement of the environment
• Look for opportunities to set demand - side energy management strategies
• Appreciate the importance to your organisation of choices with energy suppliers

A working knowledge of basic engineering principles is required. Adequate industrial experience in operating and maintaining energy intensive equipment and processes will enable better appreciation of the topics discussed.
