摘要
Compared with that in cities, energy efficiency of rural houses is lagging behind, with high total energy consumption, low efficiency and poor indoor thermal environment. Beijing is the first area to promote the energy-saving renovation of existing rural buildings on a large scale, systematically, at the whole-city level in China. Through government symposiums, field surveys, simulation analysis and other research methods in this article, the implementation scheme and policy system for the energy-saving renovation of rural buildings in Beijing were sorted out, analyzed and evaluated. The following conclusions are drawn: Beijing has completed energy-saving renovations of more than 1 million rural households; the average energy-saving rate of the thermal insulation renovation of rural houses in Beijing is about 30.0%; the average room temperature has increased by 2.6 °C after the renovation; Beijing can achieve the annual energy conservation of 590,000 tons of standard coal by the end of 2016 after the insulation renovation work of 710,000 rural houses. Beijing’s experience with the energy-saving renovation of rural building envelopes should lead to further analysis, verification and optimization in other similar climatic zones, and the average energy-saving rate in the promoted cities can achieve 30.0% above.
