LEED-AP-O+M Exam Dumps : LEED AP Operations + Maintenance (LEED AP O+M)

the mercury content of the new T8 lamps remained the same; however, the average life of the bulb increasedJust Short Explanation: The decrease in the average picogram per lumen hour indicates an improvement in the environmental impact of the lamps. This can happen if the mercury content remains constant while the lifespan of the lamps increases, resulting in less mercury used over time per unit of light produced.

References: The information about T8 lamps indicates that newer models are designed to be energy-efficient with a longer lifespan while maintaining a low mercury content, which would contribute to a lower picogram per lumen hour ratio12.

The correct answer is A because a table of lighting controls installed is the required documentation for Option 1.Lighting Controls in Indoor Environmental Quality Credit, Interior Lighting, as stated in the LEED v4.1 O+M Reference Guide1.The table must include the type and location of each lighting control device, the controlled lighting power, and the percentage of lighting power controlled by each device1. The other options are incorrect because they are either not required or relevant for this option.

This answer is correct because it matches the requirement of the Energy and Atmosphere Credit, Optimize Energy Performance, which aims to reduce the environmental and economic impacts associated with excessive energy use. The credit requires projects todemonstrate an improvement in energy performance compared to a baseline building, using one of the three options available.For buildings eligible to receive an energy performance rating using the Environmental Protection Agency’s ENERGY STAR® Portfolio Manager tool, the option is to achieve a rating of at least 50, which corresponds to the median energy performance of similar buildings nationwide1. The other options are incorrect because they are either higher than the minimum rating or not applicable to this option.
