Two Timberland mall shops have earned LEED certification through the Retail Commercial Interiors pilot program, making them the first mall-based stores in two states to earn the LEED seal.

The Timberland store in the Peabody, Mass., North Shore Mall earned gold certification and the company's location in the Rockingham Mall in Salem, NH, earned silver certification.

Both stores were constructed using 100 percent reclaimed lumber, repurposed 100 percent of stockroom shelving and reduced water use by 50 percent. The Peabody store recycled 90 percent of its construction waste, and the Salem store recycled half of its construction waste. Also, 90 percent of the equipment and appliances in the stores are Energy Star eligible.

Timberland is one of 40 companies participating in the LEED-Retail Commercial Interiors pilot program. Since 2004 the company has undertaken a number of initiatives to make energy-efficient improvements, power facilities with solar and other clean energy sources, plant trees, reduce chemical use, recycle cutting scraps, use organic cotton and become carbon neutral by 2010.
