The poor thermal performance of rural buildings and the severe pollution caused by coal combustion in northern China are urgent problems that need to be addressed. To solve these two issues, the current status of building envelopes in rural houses in northern China and the commonly used heating methods by rural households were analyzed. The study found that most rural houses lack insulation measures in their building envelopes and require energy-saving renovations. To improve the thermal performance of rural houses, the thermal performance of a rural household’s building envelope was measured and energy-saving renovations were conducted. The measurement results showed that the heat transfer coefficients of the walls, windows, and roofs decreased by 72.7%, 61.59%, and 64.99%, respectively, after the energy-saving renovations, compared to the national limit values. The thermal performance of all building envelope components met the national requirements after the energy-saving renovations. The actual statistics showed a 66.74% reduction in biomass fuel consumption per unit temperature difference after the renovations, indicating a significant improvement in energy efficiency.
