The Demonstration of Energy Efficiency Potential (DEEP) report indicates that integrated home fabric retrofits can reduce heat loss by up to 60%, with solid wall insulation providing the most significant condensation risk reduction. Findings also show current EPC ratings overstate heat loss by 42% and highlight challenges in achieving comprehensive, whole-house retrofits. For more details, visit ResearchGate .
