Lewis Elementary - LEED Profile
Project Description
-
Lewis Elementary is a new two-story school located on a 7.5-acre site, replacing the existing school built in the 1950s. The 105,595-square-foot facility is designed for 1,016 students in grades 1 through 5. The school features art and music classrooms, two science classrooms, two computer classrooms and a special populations suite. An operable wall between the dining and the multi-purpose/PE room permits the multi-purpose room to be enlarged for functions involving the stage. The main entry vestibule to the school features a tile mosaic mural of a lion, the mascot of the school. The school opened to students in October 2011.

Sustainable Overview
- Energy and water savings over the years will reduce costs
- Improved school environment greatly enhances learning environment through efficient lighting, noise control and air quality
-
Water Efficiency
- 30% water savings through low-flow plumbing fixtures used in all the restrooms
-
Energy & Atmosphere
- Exterior windows are insulated, and configured in wings, providing natural daylight and exterior views
- Energy efficient mechanical equipment includes, air-cooled screw chillers, variable-frequency drives on building pumps, efficient low-nox boilers
- Interior lighting uses high-efficiency long-life T-8 lighting
- Occupancy sensors turn off lights off when no occupants are in the room
- Dual-level switching in the classrooms for reduced light fixture use when not needed
-
Materials & Resources
- Landscaping features native plants, requiring less irrigation, maintenance, pesticides, and fertilizers
- 98% of the demolition materials and construction waste was diverted from landfill by recycling
- 23% of the materials were extracted or manufactured within 500 miles of the site
- More than 20% of the building products, excluding mechanical, electrical, and plumbing systems, are made with recycled materials
- Roofing materials, as well as parking lot materials, reduce heat absorption on the site, minimizing impact
- 95% of wood is Forest Stewardship Council (FSC) certified, supporting responsible forest management
- Noise in the classrooms is reduced by designing high STC rated wall partitions and ceilings
-
Indoor Environmental Quality
- Air-quality strategies: keeping the ductwork clean and covered, testing at the completion of construction
- Building is designed for proper ventilation to keep the air clean and fresh
- CO2 monitors are provided, and copy machines and chemical rooms have exhaust fans
- Roll up mats at every entry scheduled for weekly cleaning
- All adhesives, sealants, paints, coatings, flooring systems and composite wood products meet the requirements for low VOC (Volatile Organic Contaminants)
-
Innovation in Design
- More than 80% of the students live within three-fourth of a mile from the school and are encouraged to walk and ride bicycles, with the provision of ample bike racks and dedicated walking and bike paths
- Preferred parking is provided for low-emitting and fuel-efficient vehicles to encourage use of environmentally friendly vehicles
- Recycling is encouraged with the incorporation of a centrally located recycling station
-
