For automatic lighting shutoff, buildings larger than what square footage are affected?

1. 2,500

2. 5,000

3. 10,000

4. 15,000

The correct answer is: 5,000

Buildings larger than 5,000 square feet are affected by automatic lighting shutoff regulations. This requirement is established to promote energy efficiency and reduce unnecessary consumption of electricity in larger spaces, where lighting can be left on for extended periods even when the area is unoccupied. The choice of 5,000 square feet as a threshold is significant because it targets medium to large commercial buildings, which are more likely to have extensive lighting systems that can lead to substantial energy waste. By implementing automatic shutoff systems, these larger buildings can achieve greater overall energy savings, which aligns with modern energy conservation practices and regulations aimed at reducing environmental impact.
