“…The current state of research on lighting prediction is limited to the study of daylight [10][11][12]16,[20][21][22], with the significance of artificial lighting in energy consumption and overall building efficiency being largely overlooked. A more comprehensive approach is therefore required to accurately predict and optimize both natural and artificial lighting usage.…”

“…A significant drawback of utilizing one type of [10,16,20,22] prediction methodology for building energy consumption is the user's inability to ascertain its suitability for a specific application with certainty. This frequently results in a dearth of essential data regarding the method's efficacy and generalizability.…”

This article presents a comparative analysis of two prominent machine learning techniques for predicting electricity consumption in workplace lighting systems: polynomial regression analysis and artificial neural networks. The primary objective is to assess their suitability and applicability for developing an accurate predictive model. After a brief overview of the current state of energy-saving techniques, the article examines several established models for predicting energy consumption in buildings and systems. These models include artificial neural networks, regression analysis and support vector machines. It then focuses on a practical comparison between polynomial regression analysis and an artificial neural network-based model. The article then looks at the data preparation process, outlining how the data is used within each model to establish appropriate prediction functions. Finally, it describes the methods used to evaluate the accuracy of the developed prediction functions. These functions allow the prediction of lighting consumption based on external lighting intensity. The article evaluates the accuracy of the developed prediction functions using the root mean square error, correlation coefficient and coefficient of determination values. The article compares these values obtained for both models, allowing a conclusive assessment of which model provides superior accuracy in predicting lighting consumption based on external lighting intensity.
