Twin Lakes Elementary School is a LEED® Silver certification candidate in Elk River, Minnesota and opened in September of 2007 to 750 students. Elk River is an outer ring suburb of the Twin Cities and is growing by 500 students per year. New schools are an absolute necessity. 

This 100,000-square-foot elementary school is sited on existing farmland donated by a developer (American Homes) who will soon have 750 homes surrounding the new school. The core services of the firm (Kitchen, Cafeteria, Administration, Mechanical/Electrical) are built for a capacity of 1,000 students. Future expansion is built into the design. The site design is configured with security in mind. All visitors enter from the south and the visitor entry, bus drop-off, and playgrounds are visible from the principals office. 

LEED® principals employed on the project are a green roof, 100% daylight to classrooms and working spaces, light shelves and shades, displacement air systems, superinsulation, FSC certified wood products, 25% recycled materials, durable materials, minimal water usage, healthy indoor atmosphere, site ponding, renewable energy, and numerous LEED® categories.

The character of the building is appropriate to a country school with red brick, sloped roofs, dormers, and bell tower. The plan of the school has the cafeteria central to the first level and the media center central to the second level. Classrooms are divided into 6 houses, each centered around a resource center that can be converted to a classroom when the student population rises. The central areas have panoramic views of the countryside and the north and east portions of the building are surrounded by holding ponds. The media center opens into a green roof that can be used as a teaching station. Sage glass is used in the Science Room displaying dimmable windows from a wall switch. Forty-two light tubes are used throughout the second floor and, with light sensors everywhere, produce enough light to keep the corridor lights off most of the daylight hours. 

This school design was selected in a design competition held by the Elk River Area Schools ISD 215 in 2004 and was intended to be a prototype school for future schools in the Elk River, Otsego, Rogers, and Ramsey, Minnesota townships.
