Two Ways the Japanese Reduce A/C & Heating Costs

 

Method 2

We know that composting is good for our gardens, but what about heating our homes? Harnessing the heat generated by the composting process to heat our homes sounds like a far-fetched idea, but it’s been proposed before and experimented with quite successfully decades ago. Students at Japan’s Waseda University built this intriguing prototype that is heated by composting straw encased within acrylic boxes that make up the house’s perimeter walls. In the summer, straw will dry inside transparent window shelving which act as “heat shield panels,” thus releasing moisture that will help cool the ambient temperature. During winter, the fermenting straw will give off heat thanks to the microbial process that gradually breaks down the organic matter.
