Sustainable Architecture—What’s Next?

Sustainable architecture encompasses more than energy efficiency, zero carbon dioxide (CO2) emission or renewable use in the built environment. It also needs to alleviate overall impacts on natural environment ecosystem that surrounds it. may be argued primitive vernacular (architecture without architects) and operated using local techniques resources alone can considered sustainable. Yet later, after 1992 Rio Conference its declarations, specific definitions emerged putting weight rational of land area, materials energy, preferably local, as well area efficient planning, economy recyclability. The advantage this is reduce ecological footprint buildings climate gas emissions from a sector represents 35–50 percent global emissions, depending how one counts. This paper clarifies concepts, questions cemented truths points way forward by asking; what’s next?
