What is the minimum HERS index score required for climate zones 1-5?

The minimum HERS (Home Energy Rating System) index score required for climate zones 1-5 is 85. This score is a benchmark that helps to evaluate the energy efficiency of a home. HERS index scores are used in LEED certification to establish how well a building is performing in terms of energy use. A lower score indicates better energy performance, meaning that a home rated at 85 is more energy efficient compared to a higher score.

In climate zones 1-5, which typically represent warmer climates, the target of a score of 85 ensures that homes are built and rated with a sufficient level of energy efficiency to promote sustainability. This requirement aligns with the LEED credits aimed at reducing overall energy consumption and greenhouse gas emissions from residential buildings.

Meeting the HERS score of 85 helps builders and homeowners understand the energy performance of their homes and encourages the implementation of better construction practices and more energy-efficient technologies, contributing to overall environmental goals.
