案例简介：迈克尔·山下 (Michael Yamashita) 的照片 @ yamashitaphotos/塑料太阳能温室占据了中国西北长城沿线的景观，使农业成为全年的职业。冬天要保持热房子温暖，需要用稻草制成的毯子来保温。黎明时升起以捕捉阳光，日落时降低以减缓热量散失，内部温度保持足够温暖，可以在接近冰点的温度下生长黄瓜。中国占全球被动式日光温室使用的90% 以上。# 温室 # 被动太阳能 # 长城 # greatwallofchina

案例简介：Photos by Michael Yamashita @yamashitaphoto / Plastic solar greenhouses dominate the landscape along the Great Wall in northwest China, making farming a year-round occupation. Keeping a hot house warm in winter requires a blanket made of rice straw for insulation. Raised at dawn to capture the sun and lowered at sunset to slow heat loss, the inside temperature stays warm enough to grow cucumbers in near freezing temperatures. China accounts for more than 90 percent of passive solar greenhouse use worldwide. #greenhouses #hothouse #passivesolar #greatwall #greatwallofchina
