Learning from Nature, Beyond Carbon Zero
This document discusses how buildings can emulate natural systems and operate in a closed-loop, sustainable manner like forests. It provides the example of the Druk White Lotus School in Ladakh, India, which uses passive solar heating, natural ventilation, local materials, and other strategies to be energy self-sufficient with no waste output. The document argues that buildings today operate like unsustainable "weeds" by only consuming resources, while nature demonstrates closed-loop systems where everything is recycled or reused. It poses the question of how designers can help buildings behave more like forests and close resource cycles.

How can wedesigners help to close the cycle? 作为设计师，我们如何帮助形成这一循环？ Work with many different professionals, not only designers, as a sustainable solution is always the fruit of a true multidisciplinary approach: material experts, ecologists, sociologists, engineers, etc. 与各行各业的专业人士合作，例如材料专家、生态专家、社会学家和工程师等，而不仅 仅是和设计师；可持续性解决方案终将是多学科共同研究得出的成果。 Seek for flexible solutions that can be changed or adapted to future changes. 寻求灵活的解决方案，可适应未来的变化。 Look for win-win solutions, where a by-product of one process becomes the source for another process. 寻求双赢的解决方案，其中某个过程的副产物可成为另一个过程的能源。 Incorporate many different strategies; one strategy only will give you only a partial benefit but will not achieve a sustainable building alone. 混合采用多种不同的策略；单一的策略只能带来有局限性的利益，而无法实现可持续性 建筑的目标。 Don’t forget that architects and designers have a huge responsibility towards society. 别忘记建筑师和设计师对社会应负有的重要责任感。
