retrofit

Retrofit refers to the process of updating or modernizing existing equipment, buildings, or systems with new technology or features to improve performance, efficiency, or safety. Instead of replacing everything, retrofit involves adding new components or making modifications to existing ones. For example, installing energy-efficient lighting in an old building or upgrading a vehicle's engine to meet new emission standards are retrofit projects. This approach helps extend the lifespan of the original asset while meeting current standards and needs, often at a lower cost than a complete replacement.
