Langley Library earns LEED Silver, first certified Sno-Isle building

Langley Library has earned LEED Silver certification, making it the first Sno-Isle Libraries building to reach that level. For Island County residents, that means the historic branch’s remodel delivered more than a fresh look, it now carries a nationally recognized sustainability rating tied to more efficient use of energy and resources.

The Washington State Library announced the milestone, and Sno-Isle Libraries said the Langley branch became its first LEED Silver certified building. LEED Silver is awarded to projects that meet a set of sustainable building standards, and for a public library that can translate into a more efficient building profile and, over time, better control over operating costs.

The certification grew out of a major remodel of the Langley Library, which Sno-Isle Libraries said received a $600,000 state grant for the historic project. The branch was scheduled to close for construction on Feb. 17, 2024, with library service moving to the South Whidbey Community Center on Feb. 23 while the building was being worked on. By Oct. 17, 2025, the newly renovated Langley Library was back in use.

Sno-Isle Libraries has also highlighted the project in a news item titled “Langley Library Becomes Sno-Isle Libraries First LEED Silver Certified Building,” along with a remodel overview for the branch. The result gives Whidbey Island a visible example of how a publicly funded building can be preserved, upgraded and certified under a sustainability standard at the same time.

For Langley, the distinction matters because the library is not just a community landmark, it is now the system’s first certified model for future work. On Whidbey, where public buildings often have to balance limited budgets, older structures and rising expectations for efficiency, the remodeled library offers a local benchmark for how county and municipal projects can pair preservation with lower-impact operations.
