The Leopold Center is the headquarters of The Aldo Leopold Foundation – a group devoted to advancing the causes of land health and conservation. True to the spirit of esteemed environmentalist Aldo Leopold, the building is a marvel of eco-friendly, sustainable design. Completed in 2007 and located in Baraboo, Wisconsin, The Leopold Center has received the Platinum LEED® Certification from the U.S. Green Building Council. In fact, it was the first building to be recognized as carbon-neutral by the USGBC. The Leopold Center is a net zero energy building – meeting all of its own energy requirements – and using 70% less energy than a similarly sized building built to code.

Pella® Architect Series windows are a key component of The Leopold Center's incredible energy efficiency. Chosen for their outstanding insulating properties and low solar heat gain coefficients, the more than 200 aluminum-clad wood double-hung, casement and awning windows bring abundant daylight into the building and provide delightful views to the outside environment.

The energy efficiency of Architect Series windows is just one of many examples of how Pella – like The Aldo Leopold Foundation – strives to be an environmental steward. Pella has been recognized as an ENERGY STAR® Partner of the Year four years in a row because of their commitment to delivering energy-efficient products Pella works with wood vendors who practice responsible harvest and forest replenishment. All of which made Pella windows the perfect choice for The Leopold Center.
