What is the minimum percentage of ENERGY STAR, hard-wired fixtures for the Advanced Lighting Package credit?

The Advanced Lighting Package credit under LEED recognizes the importance of efficient lighting design in enhancing energy performance. To qualify for this credit, a project must ensure that at least 60% of the hard-wired lighting fixtures installed meet the ENERGY STAR certification criteria. This requirement is in place to promote the use of high-efficiency lighting technologies that contribute to overall energy savings in buildings.

Choosing a minimum threshold of 60% strikes a balance between encouraging energy-efficient practices and allowing for some flexibility in lighting design. Fixtures that are ENERGY STAR certified have been tested and verified to meet rigorous efficiency standards, which helps reduce energy consumption and operating costs while also improving occupant comfort and well-being through better-quality lighting conditions.

The higher the percentage, the greater the assurance of energy efficiency; however, the specification of 60% serves as a practical goal for many projects without imposing overly stringent requirements that could hinder creative design solutions. This policy aligns with broader sustainability goals by promoting significant contributions to energy savings while still accommodating the diverse preferences and needs of different architectural designs.
