Sustainable Building Strategies
From its inception, this facility has been intended to be a demonstration
project on sustainable building features. The architecture and engineering team
developed design approaches and strategies that were used on subsequent City of
Los Angeles projects. The LEED Green Building Rating System was used as a
planning tool from the project's inception. The library is being submitted for
Platinum LEED certification from the United States Green Building Council (USGBC)
in the summer of 2004. The CIWMB provided a
$250,000 direct grant for
added sustainable features for this project.
Energy Efficient Systems
- A landmark passive cooling tower conditions the interior space and
houses an Environmental Awareness Center.
- The building form uses light shelves, louvers, overhangs, skylights,
and planning strategies to provide high-quality glare-free daylight during
operating hours.
- A programmable lighting control system with photocells and motion
sensors allows efficient integration of the daylighting and electric
lighting design.
- Exterior insulation on CMU block wall facilitates night venting to
assist with building air conditioning.
- The roof is Energy Star compliant with high emissivity and insulated
beyond Title 24 requirements.
- Photovoltaic cells provide about 15 percent of the building's estimated
regulated electricity need.
- Green Power was purchased to offset 100 percent of the building's estimated
regulated electricity use for two years.
Materials and Resources
- Over 75 percent of construction waste was diverted from landfills into the
recycling market.
- Recycled content building materials are used for structural elements,
flooring, walls, casework panels, and tiles.
- A large portion of the materials for the library came from within 500
miles of the site.
Storm Water Management
- Landform bioswales create undulating earth forms that retain, and
filter runoff at the north part of the site. All of the hardscape runoff
at the parking area, driveway entrance, and interior courtyard is directed
to landscaped infiltration areas that slow, retain, and filter runoff
prior to this water being processed through a Baysaver filtration system.
- The Baysaver treats overflow from the landscape strategies listed as
well as treating all of the roof runoff. It was designed to treat a
25-year storm occurrence. A gabion wall runs the length of the building at
the south edge of the site to capture and filter incidental runoff not
being treated by the other systems.
Water Conservation
- Landscaping and high efficiency irrigation systems reduce estimated
site water usage by over 50 percent.
- Water fixture flow controls and efficient fixtures reduce estimated
domestic water use by 30 percent above Energy Policy Act requirements.
