LEED Certified Libraries of the County of Los Angeles Public Library

Sustainability and the Library

The County of Los Angeles is committed to greener spaces and environment. Explore each section to learn about the sustainable practices incorporated in our library buildings. In January 2007, the Los Angeles County Board of Supervisors adopted rules to require that all new County buildings greater than 10,000 square feet and funded on or after February 15, 2007 be certified LEED Silver, Gold or Platinum.

What is LEED Certification?

LEED logo

LEED certification is the recognized standard for measuring building sustainability. Achieving LEED certification demonstrates the building project as truly “green.” The LEED rating system, administered by the U.S. Green Building Council, is designed to promote design and construction practices that reduce the building’s negative environmental impacts. LEED certification, which includes a rigorous third-party commissioning process, offers four certification levels for new construction and major renovation projects – Certified, Silver, Gold, and Platinum – that correspond to the number of credits accrued in five categories: sustainable sites, water efficiency, energy and atmosphere, materials and resources, and indoor environmental quality. Learn more about the LEED rating system on the U.S. Green Building Council website.

West Hollywood Library LEED Gold

Sustainable Sites

The building is situated within the West Hollywood community and the vast open space of West Hollywood Park. Over 10 community services are located within ½ mile of the site. The building is in close proximity to multiple public transportation options as well as provide facilities (bike racks & shower facilities) for individuals biking to the complex. A 90-car parking garage was built to serve the Library with grass and vegetation on the roof top thus reducing heat effects.

Water Efficiency

Baseline water reduction methods used at the site include low-flow sinks, water-saving toilets and waterless urinals in the restrooms resulting in 44% reduced water use.

Energy & Atmosphere

Energy efficiency measures incorporated into the building include efficient fenestrations, solar shading, efficient chiller system, reduced light power densities and a photovoltaic renewable energy system. This photovoltaic system produces solar energy equivalent to nearly 5% of the building’s total energy use.

Materials & Resources

During construction over 2,800 tons (96%) of on-site generated construction waste was diverted from landfills. Additionally, more than 25% of all construction materials were sourced locally and 14.5% of the total building material content by value were manufactured using recycled materials. Nearly 2/3 of the total wood-based materials in the building were harvested from certified forests.

Indoor Environmental Quality

Indoor conditions are of particular note especially in a public building. During construction low-emitting adhesives, sealants, coatings, carpets and paints were used throughout the building. Prior to occupant move-in, a two-week flush out of the building was performed to settle and remove all particles and pollutants. Carbon dioxide monitoring sensors are installed throughout the facility which has daylight and views in 90% of the building.

Innovation & Design

A LEED Accredited Professional was a part of the design team from the early stages of design. With the assistance of this professional the project was able to achieve bonus exemplary performance results in diversion of on-site generated construction waste from landfills, water use reduction and vegetated open space. The building is further maintained through a “green housekeeping program.
