RdSAP 10 Conventions v12.1 Updates for Domestic Energy Assessors

The release of RdSAP 10 Conventions v12.1 brings important updates for Domestic Energy Assessors (DEAs). Staying up to date ensures accurate Energy Performance Certificates (EPCs) and compliance with the latest assessment standards. This article highlights the key changes and practical guidance for DEAs to implement these updates effectively.

Room in Roof: Key Changes

The conventions now provide updated guidance on modelling roof spaces, including insulation levels and dormer areas. These changes can significantly affect energy performance calculations. For detailed practical tips on inspecting roof spaces, see our guide on inspecting lofts and roof spaces for EPC assessments.

Windows Assessment Updates

Updated rules now require more detailed recording of window types, frame materials, and glazing to ensure accurate thermal performance. For advice on assessing different window types, read our practical guidance on assessing windows for energy efficiency.

Lighting Considerations in RdSAP 10

The conventions now distinguish between LED and CFL bulbs and require accurate counts of lighting units. This ensures lighting efficiency is correctly reflected in EPCs. Related guidance is available in our article on recording lighting in EPCs.

Practical Implications for DEAs

DEAs should pay close attention to roof insulation, window types, and lighting during assessments. Accurate recording supports compliance and reduces the risk of EPC inaccuracies. Familiarity with the latest RdSAP 10 software tools is also essential to implement these updates effectively.
