Stroma Tech carries out the water efficiency calculations required for new dwellings to comply with Part G of the Building Regulations and Code for Sustainable Homes.
Under Part G of the Building Regulations, a maximum water usage figure of 125L per person per day must be achieved. Non-compliance may adversely affect a dwelling’s Standard Assessment Procedure (SAP) calculation, and consequently its Energy Performance Certificate (EPC) rating.
The Code for Sustainable Homes imposes targets related to water usage through the WAT 1 category.
Calculations must be submitted at both the design and ‘as built’ stages; if your specification is not on target to meet the required limits, our experienced assessors can provide advice on how to resolve this, ensuring a smooth submission to Building Control.
