Water Efficiency Calculation | Part G | For new dwellings and conversions in Surrey
|
Water efficiency calculations have been part of building regulations since 6th April 2010. Approved Document G is part of the government's action plan to ensure the UK is prepared for the future, including the forecasted increase in average summertime temperature and decrease in rainfall during the summer months. Due to these projections, building regulations now include limitations for the usage of water to 125 litres per person per day, for all newbuilds and conversions built post April 6th 2010. Local planning authorities also have permission to reduce this target to 110 litres per person per day if they choose to. It is good practice to have water usage calculations completed prior to commencing work on the construction of your property, as you can determine whether your property will be compliant with the Part G regulations before spending any money on installing appliances and fittings (as these affect the outcome of the calculations). |
