Study on energy retrofits for rural residential envelopes in Northwest China.

ABSTRACT: Rural dwellings in Northwest China are typically self-built, lack energy-saving measures, and suffer from high energy consumption and poor thermal performance. Retrofitting building envelopes is a key strategy to improve energy efficiency and reduce carbon emissions. However, most existing studies focus on single-factor retrofits and single-objective evaluations, limiting their comprehensiveness and practical application. This study addresses these gaps by investigating single- and multi-factor retrofit scenarios for a typical rural house in Dingxi City of Northwest China. Using orthogonal experiments and DeST-h simulations, optimal combinations of envelope elements were identified, and the entropy method was applied to evaluate energy savings, incremental costs, cost-effectiveness, paybac
