Buildings are responsible for 39% of global energy-related carbon emissions; 11% come from materials and construction, and 28% come from operational emissions (the energy required to heat, cool, and power). Embodied carbon will contribute an increasing amount to the emissions from new buildings in the future as carbon emissions from building operations continue to decline. This study examined several construction methods and materials to evaluate alternatives for remodeling a residential villa. A villa in the Al-Qassim Region, Buraidah, served as a case study for this research. The methodology employed provided a meticulous appraisal of the building materials and techniques currently in use. The structural integrity and cost comparison between the recommended scenarios and the existing situation were examined in this study. Based on this assessment, alternative building materials and techniques are found, and their potential use in retrofitting the villa is investigated. Six options have been investigated: (1) Insulating Precast System, (2) Autoclaved Aerated Concrete, (3) Tunnel Form, (4) Light Gauge Steel, (5) Cladding Materials, and (6) Nanotechnology materials. The construction project can achieve cost savings, enhanced thermal comfort, and long-term environmental sustainability by implementing these suggested technologies. In conclusion, even though new construction technology systems could be more expensive initially, they can save money over time by increasing building lifespan, lowering maintenance requirements, and improving energy efficiency. In the Saudi Arabian market, selecting between innovative construction technology systems and conventional construction methods is also influenced by several other factors, including client preferences, local restrictions, sustainability goals, and project requirements.
