What type of analysis might a HERS rater perform on lighting?

The evaluation of the efficiency of installed lighting fixtures and potential upgrades to LED bulbs is central to a HERS rater's responsibilities. This process involves assessing how much energy the current lighting fixtures consume and determining if upgrading to more efficient options, such as LED bulbs, would significantly reduce energy usage. LED bulbs generally consume less power and have longer lifespans compared to traditional incandescent or halogen bulbs, resulting in lower electricity bills and a reduced carbon footprint.

By focusing on the efficiency of lighting, the HERS rater can provide valuable insights that help homeowners make informed decisions on energy-saving upgrades. This analysis aligns with the overarching goal of improving a home's overall energy performance, which is the primary objective of the HERS rating system. In contrast, other types of analysis, like inspecting aesthetic qualities or measuring brightness, do not have a direct impact on energy efficiency and may not provide actionable recommendations for improving the home's energy performance.
