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.

Sustainable Sites

Heat Island Effect: Roofing materials with a high Solar Reflective Index (SRI) to reduce the absorption of thermal radiation into the building. Permeable pavers were installed at parking stalls and at pedestrian walkways. During construction, several measures were implemented to reduce the amount of construction-generated waste and pollution entering the municipal pipelines, such as minimizing mud and dust leaving the construction site and recycling 75% of the construction waste.

Water Efficiency

All the plumbing fixtures are designed for maximum reduction in water use. The urinals are High Efficiency, the water closets are High Efficiency and Water Sense Approved and the sinks are all aerated and timer controlled. Potable water usage is more than 35% lower than the average usage of comparable buildings. Non-invasive and drought tolerant plants were used to reduce the requirements of potable water for irrigation by more than 50% than the average usage of comparable buildings.

Energy & Atmosphere

The heating ventilation and air conditioning (HVAC) equipment uses non-ozone depleting refrigerants. The HVAC and lighting systems have been optimized to perform at least 48% more efficiently than required by California Building Code, after factoring in the energy provided by the solar panel system. More than 13% of the total building electrical energy consumption is provided through renewable energy photovoltaic (solar) panels.

Materials & Resources

During construction the County and General Contractor worked to divert over 75% of the construction debris generated so that it did not wind up as landfill. 20% of the materials used to construct the building and associated site work are a combination of post-industrial and post-consumer recycled materials. Forest Stewardship Council certified wood products were used to ensure that the project did not indirectly support deforestation.

Indoor Environmental Quality

To improve indoor air quality, there are a series of carbon dioxide monitors throughout the library interior which can control the HVAC system to increase outside air flow if necessary. Volatile organic compounds in adhesives, sealants, paints, and other coatings have been kept to a minimum. The building is designed to give more than 90% of the regular occupant access to natural day lighting rather than limiting lighting to artificial light. This reduces building energy usage.

Innovation & Design

Several LEED credit thresholds were exceeded during the design and construction, e.g. Daylighting, Green Power and Renewable Energy.
