Water Efficiency Calculations are required for new dwellings in order to achieve compliance with Code for Sustainable Homes and Part G of the Building Regulations. These calculations must be submitted at the design AND ‘as built’ stages. HRS Services can offer Water Efficiency Calculations via our sister company Stroma Tech.
Compliance with Part G
Part G of the Building Regulations states that new dwellings must achieve a maximum water usage figure of 125 litres per person per day. If the dwelling is non-compliant then there could be a detrimental effect on the SAP calculation (Standard Assessment Procedure) and therefore the EPC (Energy Performance Certificate).
Compliance with Code for Sustainable Homes
The Code for Sustainable Homes stipulates the targets for water usage that must be achieved by new dwellings through the WAT 1 category:
- Levels 1 & 2 – less than or equal to 120L per day
- Levels 3 & 4 – less than or equal to 105L per day
- Levels 5 & 6 – less than or equal to 80L per day
