The construction industry is increasingly embracing sustainable solutions to meet global energy efficiency goals, with innovative building systems like Gablok emerging as a transformative approach to residential architecture. Gablok homes utilize insulated modular wooden blocks, offering a high-performance, energy-efficient alternative to traditional construction methods. This paper explores the energy efficiency of Gablok homes, focusing on their thermal insulation properties, reduced energy consumption, and overall environmental impact. Key benefits such as ease of assembly, minimized construction waste, and compatibility with renewable energy systems are highlighted. Additionally, the study investigates the lifecycle performance of Gablok structures, emphasizing their role in reducing carbon footprints and operational energy costs for homeowners. By analyzing case studies and comparing Gablok homes with conventional residential buildings, this research underscores their potential to revolutionize sustainable housing. The findings advocate for broader adoption of Gablok technology as a practical, scalable solution for eco-friendly residential construction, aligning with the principles of sustainable development.
