目前,日益增多的工程项目需要绿色建筑认证,美国“LEEDTM”是世界最具权威的认证评估体系,评估工作共有七块内容,保护和节约水资源(Water Efficiency)是其中一项主要工作。采用有效的节水措施,通过节水计算,即可得到相关的评估分值,为实现工程的LEED认证提供有力依据。结合工程实例对节水计算和措施进行详细阐述,以便在水系统的设计中大力推广绿色建筑节水措施,推进节水型生活用水器具的认证工作,保护和节约水资源。
At present, a growing number of projects require green building certification. The United States “LEEDTM” is the world’s most authoritative certification evaluation system. There are seven pieces of assessment work, and protecting and saving water is one of the major tasks . With effective water saving measures, the relevant assessment scores can be obtained through water-saving calculation, which provides a strong basis for achieving LEED certification of the project. Combined with engineering examples, the calculation and measures of water saving are elaborated in order to promote green building water saving measures in water system design, promote the certification of water-saving domestic water appliances, and protect and save water resources.
