The 'Water efficiency calculator for new dwellings' is the Government's national calculation methodology for assessing water efficiency in new dwellings in support of The Code for Sustainable Homes and the Building Regulations. If you are building a new home, you will need to calculate the water consumption of the dwelling. This is calculated using a number of assumptions outlined in the guidance and is calculated in litres per person per day. The water calculator provides an on-line up to-date version of this, enabling you to comply with regulations quickly and easily.
The Government updated Part G of the Building Regulations in April 2010. This sets a whole building standard of 125 litres per person per day for domestic buildings. This comprises internal water use of 120 litres per person per day, and in that respect is in line with Code Levels 1 and 2, plus an allowance of 5 litres per person per day for outdoor water use. This will be specified using the methodology set out in the 'Water Efficiency Calculator for New Dwellings' also used for the Code for Sustainable Homes.
