Activewear giant Puma opened its first “sustainable” store in a suburb of Bangalore, India on Thursday. The 8,600-square-foot building is entirely solar powered, and more than 90 percent of the interior has direct access to natural light. The building also features a highly insulated shell that allows for cooling without air-conditioning. In addition to recessed ceilings, which facilitate the “stack effect” for natural cooling, an underground heat-sink system maintains temperatures at a constant 24 degrees Celsius (75 degrees Fahrenheit) throughout the year. Inside, a variety of products made from organic cotton will be sold, as well as Puma’s “Wilderness Collection,” a line of apparel, footwear, and accessories primarily sourced and manufactured in Kenya from sustainable materials.
