(CNN) -- An eco-friendly building material might have saved some of the 80 homes destroyed in a recent wildfire in Southern California. But it can't be used there. Rajesh Kanwar built his Alpine, California, house out of AAC after his previous house burned down. The masonry material, called autoclaved aerated concrete or AAC, can withstand a 2,000-degree fire for four hours, according to Underwriters Laboratories' test results. "I just think the material's awesome. There's nothing like it," said Doug Edwards, an architect whose Edwards Design Group designs and builds green homes in the Scottsdale, Arizona, area. "It's the best building material in the world."
