What makes the wigwam so great? The answer is net zero everything. These off-the-grid structures were designed to be water and energy independent. The same goes for any other traditional building type: igloo, teepee, log cabin, etc. No emissions are generated by shipping materials to the site, or during the construction process.In today’s world of green building certifications, the wigwam would be beyond LEED® Platinum and Living Building Challenge™ certified.
