Benefits Green Building method using an annually renewable resource Uses less energy consumption to harvest, produce, and transport bales than conventional methods (timber) Directly supports local economy
Benefits Utilizing a waste product of an existing industry Annual carbon monoxide production from power plants and straw burning SOURCE TONS BURNED TONS OF CARBON MONOXIDE RICE STRAW 1 MILLION 56,000 WHEAT STRAW 97,000 5,000 POWER PLANTS 25,000 California Agricultural Magazine, Vol 45, (1991)
Benefits Energy efficient due to high insulating value (R-value) Walls constantly breathe, circulating air, while still providing superior thermal insulation Walls are very soundproof
Concerns? Is my house going to burn down? No! The bales hold enough air for good insulation but compacted tightly enough to discourage combustion. High silica content in straw impedes fire The plaster can reach temperatures of 1850 degrees F for 2 hours before cracking.
Will bugs or rodents eat my house? No! There is no nutritional value in straw Burrowing can be limited by careful plaster application and tightly woven wire mesh surrounding bales Concerns?
Will my house rot? No! Walls are breathable enough that condensation is limited Concerns?
