U Value Calculations
We complete full U Value Calculations in accordance with BR443 as Part of our SAP Assessments and Part L Compliancy Reports. We can also provide U Value calculations separately for Construction specifications to ensure targets are achieved.
Calculation methods for the determination of U-values of building elements are based on standards that were developed in the European Committee for Standardisation (CEN) and the International Organisation for Standardisation (ISO) and published as British Standards. These methods are appropriate for demonstrating compliance with building regulations for the conservation for fuel and power, namely Part L of the Building Regulations for England & Wales , Section 6 of the Building Regulations (Scotland), and Part F of the Building Regulations (Northern Ireland). Calculated U-values can then be used for the Standard Assessment Procedure (SAP) for dwellings & by the Simplified Building Energy Model (SBEM) for other buildings.
