Water Efficiency Calculations

Water efficiency calculations predict water consumption in line with Part G of The Building Regulations. You need these calculations for all new builds, as well as some conversions. The water efficiency of a property is becoming increasingly important to make homes more sustainable. Furthermore, as the population grows, it is more important that water is conserved.

Water efficiency is measured in litres per person. To comply with Part G of The Building Regulations, a property must show that its water targets will not exceed 125 litres per person per day unless the planning permission for the property has specified that this needs to be reduced to 110 litres per person per day.

Water Efficiency Calculation with CAMSONS

To provide water efficiency calculations, you need to give us a complete set of floor plans showing the number of ‘wet rooms’ such as the kitchen, utilities and bathrooms. In addition, the plans will also need to show the number of facilities which will use water, such as showers, toilets, sinks, washing machines or dishwashers.

Using this information we will calculate the projected water consumption levels of your property. Generally, you’ll carry out water efficiency calculations at design stage, as part of your SAP Calculations. However, your local authority may need these measurements at any point in your project.
