It is an object of the present invention to provide hybrid construction machinery in which a power storage apparatus can be warmed up quickly and a life of the power storage apparatus can be lengthened. The hybrid construction machinery includes: an electric motor assisting a prime mover in power and generating electric power; the power storage apparatus transferring electric power to and from the electric motor; a warm-up circuit circulating a warming medium in the vicinity of the power storage apparatus; and a control device controlling circulation of the warming medium in the warm-up circuit. The hybrid construction machinery is provided with on-board equipment state detection units that detect states of on-board equipment to estimate an output request for the power storage apparatus from the on-board equipment. The control device controls circulation of the warming medium 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.
