Validation of RdSAP U-calculation methodology for traditional stone walls

Descriptions

The outputs of this work should include: - U-value measurements for all assessed walls. - Assessment of walls following the RdSAP10 methodology. This should be undertaken by an experienced Domestic Energy Assessor. - Following a property survey, a desktop exercise in which lodgement of EPCs includes the calculation of U-values using the new equations (the before case), for each of the sample properties. - Commentary on the relationship between U-values obtained by measurement and calculated values. - Quantification of the impact on RdSAP calculations of any discrepancy between measured and calculated values. - If RdSAP calculated values differ by more than an appropriate error amount as agreed with SG, the Supplier should propose an alternative approach to U-value calculation. - Production of final report, including analysis and interpretation of sample results found, and written presentation of these to Scottish Government in the report.
