Effects of climate change on long-term building heating performance of medium-deep borehole heat exchanger coupled heat pump

•Climate change compromises heating extraction attenuation by reducing building heating load.•Climate changes of different emission scenarios are tested.•Different climate zones and geological conditions are tested.•Climate change reduces unmet level of building heating load by 70.5% – 100%.•Climate change reduces heating energy consumption by 9.2% – 17.0%.
