What is meant by "Reduction in Performance Level [Change of Use]"?

• A. Lowering safety standards on a building
• B. Decreasing the building's functional efficiency
• C. Increasing operational costs
• D. Limiting structural modifications

Answer: (B)

The term "Reduction in Performance Level [Change of Use]" refers to the impact on a building when its designated purpose changes, which may lead to a decrease in its functional efficiency. Specifically, when a building undergoes a change of use, it may not perform as effectively as it did for its original intended purpose. This can manifest in various ways, such as inadequate systems to meet the new demands, leading to inefficiencies in heating, cooling, or utility use. For example, a building that was initially designed as an office may not operate efficiently if converted into a residential space without appropriate upgrades to accommodate the different needs of occupants. The focus on functional efficiency is critical, as it directly impacts the usability and effectiveness of the space after the change of use. This definition aligns closely with how changes in a building's use can necessitate considerations for its ongoing performance and suitability for its new role, which is why this option represents the correct understanding of the term.
