Description:This British Standard gives recommendations for calculating the volume of public mains water that is consumed for domestic use in non-domestic buildings. It gives recommendations for estimating the total water use from the buildings’ components, allowing consumption to be indicated on a whole building level against other buildings for best practice levels. This standard is not for use as a design guide. It provides a framework for and details the development of water use calculation methodologies in non-domestic buildings. It provides recommendations for the quality of data used to calculate water use for each component in non-domestic buildings and also standardized reporting for product performance data. It applies to both new and existing buildings and covers: Water that is sourced from unwholesome sources such as rainwater harvesting systems or greywater reuse systems;and Water that is sourced from wholesome sources including both hot and cold water.   
Overview: BS 8542:2011 Calculating domestic water consumption in non-domestic buildings. Code of practiceCalculating water use in buildings provides a means for estimating the building’s impact on water consumption. With an increasing demand for water efficiency, a standardized framework for reporting water consumption is useful to allow designers, specifiers, building managers, water authorities and product manufacturers to estimate and report water consumption in a consistent way.BS 8542:2011 gives recommendations for calculating the volume of public mains water that is consumed for domestic use in non-domestic buildings.
