摘要: In the use phase, buildings are high resource consumers, especially energy, water and even nutrients. The relationship between these resources is inseparable, nexus energy–water–food (or energy–water–nutrients) currently recognized as essential connection for sustainable development of mankind. current scenario climate change, “nearly zero energy” begin to enter reality cities in many parts world, but “zero buildings” general (and not just with regard energy) should integrate enhance constructive solutions future. Taking into account water–energy nexus, reduction consumption building cycle also reflected significant energy efficiency, considering needs heat sanitary hot pressurize public systems, abstraction, pumping treatment wastewater. design water” be based on 5R principle, which can summarized follows: Reduce consumption; losses wastes; Reuse water; Recycle Resort alternative sources. This paper a short review techniques increasing efficiency buildings, principle 5R, analyzing several special focus efficient products, harvesting rainwater reuse greywater. first two technologies already well technically dominated, while greywater, although novelty, still lacks certain developments view their generalization, health quality control issues.
