Sidwell Friends School | Washington, DC

Sidwell Friends School Achieved LEED® Platinum Certification.

Project: Sidwell Friends School

Location: Washington, DC

Architect: KiernanTimberlake Associated LLP

Product: CS 100-3 Sun Controls & Custom Light Shelves


About the Project

The Sidwell Friends School may be the nation's most environmentally-friendly school. Committed to environmental stewardship, Sidwell directed architect KiernanTimberlake to design a sustainable middle school which ultimately achieved LEED Platinum Certification in 2007. The design uses daylight as the foundation of its strategy to minimize energy use.

Working Together

Working with the CS design team, the architect specified 4-1/2' deep cantilevered sunshades with 6" airfoil blades for the school's southern exposure. The sunshades reduce heat and glare while allowing light to enter the interior. CS reflective lightshelves attached to the exterior shades direct natural daylight deep into the classrooms and hallways.

Results

Computer models indicate that CS Sunshades and Lightshelves, in conjunction with other daylight strategies, help this facility reduce the energy associated with lighting by 92% when compared to a typical code-compliant building.

At a glance:

  • CS Sunshades reduce a building's air conditioning requirement and lighting energy
  • Solar heat gain and glare are reduced
  • Natural light is directed deep into classrooms and hallways
