Energy-saving benefit analysis before and after renovation
Annual energy saved analysis before and after renovation:
Annual energy saved=Annual energy consumption before renovation- Annual energy consumption after renovation=2,022,702.2 W/h-828,642.25 W/h=1,184,060 W/h
Annual energy cost saved before and after renovation:
Annual energy cost saved- Annual energy saved X average unit price(1.25 Yuan per W/h)- 1,184,060 W/h X 1,015 Yuan/(W/h)= 1,361,669 Yuan.
