Retrofitting existing buildings primarily enhances the functionality and efficiency of older systems. This approach involves updating and improving the building’s infrastructure, such as plumbing, electrical systems, and HVAC, to meet modern standards and demands. This not only covers a range of improvements, including energy efficiency upgrades, but also incorporates new technologies that can significantly reduce utility costs and improve occupant comfort.

By focusing on these functional and efficiency improvements, retrofitting can extend the life of an existing building while simultaneously reducing its environmental impact. This makes it a more sustainable choice compared to complete teardowns or new constructions that require resource-intensive processes and additional environmental considerations.

The other options suggest benefits that do not capture the primary focus of retrofitting. For instance, while some retrofits might avoid the need for new permits, this is not universally applicable and depends on the extent of the renovations. Additionally, although retrofitting can be less costly than new construction in some cases, it might not always be the case, as the cost varies widely based on specific needs and local conditions. Lastly, retrofitting is not limited to mere cosmetic improvements; it encompasses a wide range of upgrades that improve the overall performance of the building rather than just enhancing its appearance.
