Abstract

This article aims to design and analyze energy systems for a villa to address the dual challenges of inadequate illumination and excessive electricity consumption. The study employs specialized software programs, including AutoCAD, PVsyst, DIALux evo, and T*sol, to design and dimension the villa’s energy systems. A comprehensive analysis of the photovoltaic system is conducted alongside precise architectural modelling and simulations of the interior lighting and solar water heater system. Additionally, the effectiveness of motion detectors in optimizing interior lighting to reduce energy consumption is examined, and solar lamps are integrated for the villa’s exterior lighting to promote sustainability. The findings indicate that the implementation of advanced energy system designs and the use of motion detectors can significantly enhance interior lighting while simultaneously reducing energy consumption by 30%. This paper contributes a holistic approach to energy system design in residential settings, offering innovative solutions for improving lighting quality and energy efficiency in villa architecture. The integration of renewable energy sources and smart technologies underscores the potential for sustainable living solutions in modern residential designs.
