Abstract
This article presents a comprehensive analysis of the integration of renewable energy technologies in the building sector as an effective strategy for improving energy efficiency and reducing greenhouse gas emissions. The study evaluates the performance of solar water heating systems, flat plate collectors, hybrid heating systems, and phase change material (PCM)-based technologies in terms of their technical, economic, and environmental impacts. The results indicate that the application of these systems significantly enhances thermal performance, reduces reliance on fossil fuels, and lowers carbon dioxide emissions while achieving acceptable payback periods. However, the widespread adoption of such technologies remains constrained by financial uncertainty, technical complexity, and limited institutional support. The findings highlight the necessity of a coordinated technological and policy-driven framework to accelerate the transition towards sustainable, low-carbon building energy systems.
