• Suggest practical measures for improving energy efficiency.

Lesson summary

In Ghana, we are all familiar with the challenges of "dumsor" (power outages) and the rising cost of electricity from the Electricity Company of Ghana (ECG). Every cedi spent on wasted energy is money that our families or our school could use for something else. This lesson introduces a practical skill called an energy audit. It is like being a "detective for energy," hunting for clues about where energy is being wasted. By learning how to perform a simple walk-through energy audit, you will gain the power to identify problems and suggest solutions that can save money, reduce the strain on our national power grid, and protect our environment.

Lesson notes

Concept 1: What is an Audit?

Before we talk about energy, let's understand the main idea: an audit. An audit is a systematic and official examination of something to check if it is correct, efficient, or effective. Real-life Example: Imagine your class contributes money for an end-of-term party. The class prefect keeps a record of all money received and all money spent. An "audit" would be when the teacher or another student carefully checks the prefect's record book against the receipts to make sure all the money is accounted for and was spent properly. It's a process of checking and verifying. Concept 2: What is an Energy Audit?

An energy audit is simply applying the idea of an audit to energy use. It is a systematic inspection and analysis of energy use in a building, process, or system. The main goal is to identify where and how energy is being wasted and to find opportunities to save energy without negatively affecting the output or comfort.

The simplest type of energy audit, and the one we will focus on, is called a Walk-Through Audit (or a Preliminary Audit). This involves walking through a facility and using your eyes and basic knowledge to spot obvious areas of energy waste. Concept 3: The Four Steps of a Walk-Through Energy Audit

Evaluation guide

• Perform a walk -through energy audit of a facility and identify sources of energy wastage.
• Initiating Talk for Learning: In a moderated discussion, learners discuss what an audit (in general) is,
• its importance, and processes. From the general understanding, learners explain what an energy audit is.
• Share with learners the procedure for performing a walk -through energy audit of a facility and how to
