Hybrid construction machinery has a power storage apparatus that can be warmed up quickly and has a lengthened life. The machinery includes an electric motor assisting a prime mover in power and generating electric power. The power storage apparatus transfers electric power to and from the electric motor. A warm-up circuit circulates a warming medium in the vicinity of the power storage apparatus, and a control device controls circulation of the warming medium. On-board equipment state detection units detect on-board equipment states to estimate an output request for the power storage apparatus from the on-board equipment. Circulation of the warming medium is controlled based on a temperature of the power storage apparatus and a determination temperature for determining whether to circulate the warming medium in the warm-up circuit. The control device further varies the determination temperature according to a result of detection by the on-board equipment state detection units.
