Which of the following is a common benefit of retrofitting a building?

Retrofitting a building primarily aims to improve its performance through upgrades to systems and materials without complete reconstruction. One of the most significant benefits of retrofitting is increased energy efficiency. This improvement is often achieved by updating insulation, windows, heating, and cooling systems, which can significantly reduce energy consumption. As a result, retrofitted buildings often see lower utility bills and a smaller carbon footprint, contributing to both environmental sustainability and operational savings.

While retrofitting can sometimes lead to improved architectural design or greater space for occupants, these are less common motivations and may not be the primary outcomes of the retrofitting process. Higher construction costs are typically associated with retrofitting due to the need for specialized materials and technology, making energy efficiency the standout benefit that supports both financial and environmental goals.
