One benefit of using building automation technologies is ___.

• A. Optimized building performance
• B. Installing new electrical equipment
• C. Decreasing maintenance staff
• D. Using smaller wire sizes

Answer: (A)

Building automation technologies coordinate how building systems operate by using sensors, controllers, and software to adjust HVAC, lighting, and other loads in real time. This coordinated control aims to run equipment only as needed, at the right times and levels, which reduces energy waste and keeps conditions comfortable and consistent. That combination—efficient energy use, stable comfort, and reliable operation—defines optimized building performance.

Other options describe activities or outcomes that aren’t the primary benefit of automation. Installing new electrical equipment is a separate task, not the automatic performance benefit. Decreasing maintenance staff isn’t guaranteed and isn’t the main goal of automation, which focuses on smarter operation and monitoring rather than headcount changes. Using smaller wire sizes isn’t an inherent benefit of building automation and depends on specific design and electrical loading, not the automation itself.
