Sustainability is a mantra that beats quietly throughout Chepu, an off grid eco-lodge on Chiloe Island, built with sustainable materials. The owners constantly reinvest in eco technology not only to improve their footprints but also to educate guests. Herein lies the innovation. They have installed sensors in water and electric sources, and disseminate usage data to tablets in each bedroom. Guests can, therefore, see their resource usage as well as their Eco Limits – ie. maximum daily resources per person. Eco guests are ‘rewarded’ with a tree being planted in Patagonia or the financial equivalent as a refund. Individual usage is also shown on a screen in the main hallway for all to see. Because at Chepu, sharing is caring.
