Which credit can be positively impacted by performing an ASHRAE level 1 energy audit?

Performing an ASHRAE Level 1 energy audit primarily focuses on assessing energy use and identifying potential improvements in energy efficiency for existing buildings. This type of audit provides a fundamental understanding of where energy is being consumed and where savings can be achieved, often considering equipment and lighting systems.

In this context, the credit related to purchasing lamps is positively impacted because the audit can lead to recommendations for more efficient lighting solutions, such as the replacement of outdated lamps or the purchase of ENERGY STAR-rated replacements. By replacing less efficient lamps with energy-saving options, a building can reduce its overall energy consumption, which aligns with the goals of the credit that encourages sustainable purchasing practices for lighting.

The other options do not align as directly with the findings of a Level 1 energy audit. For example, while the audit may highlight general efficiency opportunities, it is less directly linked to indoor air quality or outdoor air quality considerations, which often involve different aspects of building management, such as ventilation, filtration, and overall environmental quality rather than solely focusing on purchasing efficient lamps.
