Evaluation of the Energy Efficiency Potential of Household Residential Lighting in a City: The Case of the City of Koudougou

Abstract

Energy efficiency is one of the priorities of the current political agenda. There are very few countries in which no objective has been set in terms of energy savings, energy consumption, and reduction of greenhouse gas emissions. However, these declarations of intent are not always followed by concrete actions due to the lack of adequate data for developing indicators to monitor energy consumption. It is within this framework that we initiated this study, whose main objective is to assess the energy efficiency potential of domestic lighting by focusing on four energy management actions denoted EC1, EC2, EC3, and EC4. To carry out this study, surveys (direct interviews) were conducted with households in order to collect data on lighting consumption. The results show an overall potential of 7,299.64 kWh, which represents 12.11% of total lamp consumption. A more detailed analysis reveals variable potentials depending on the areas of lighting use and the actions considered. Bedrooms exhibit the highest energy efficiency potential, accounting for 58% of total energy savings, with a total potential of 4,194.49 kWh. Living rooms contribute 32% of this potential, i.e., 2,317.19 kWh. Toilets, for their part, have a total saving potential of 611.08 kWh, corresponding to 8% of total savings. These results indicate that households can achieve substantial energy savings if they implement energy management actions in the management of the different lighted spaces.
