Retrofitting existing buildings for sustainability: Challenges and innovations (original) (raw)

Retrofitting existing buildings for sustainability is a critical strategy in addressing the environmental impact of the built environment, enhancing economic benefits, and improving social well-being. As buildings are significant contributors to global energy consumption and carbon emissions, retrofitting presents a valuable opportunity to mitigate these effects. However, the process involves numerous challenges, including technical, financial, regulatory, and logistical obstacles. Structurally, integrating new technologies with outdated systems can be complex, while high initial costs and uncertain returns on investment pose financial barriers. Regulatory issues, such as building codes and zoning laws, further complicate retrofitting efforts, and the potential disruption to occupants adds operational difficulties. Despite these challenges, innovations in sustainable retrofitting offer promising solutions. Energy-efficient technologies, such as advanced HVAC systems, high-performance insulation, and energy-efficient lighting, significantly reduce energy consumption. The integration of renewable energy sources, like solar panels, wind turbines, and geothermal systems, further enhances sustainability. Smart building technologies, including building
