  We study the loop effects on the geometry and boundary conditions of several
black hole spacetimes one of which is time-dependent and analyze the energy
measured by an infalling observer near their horizons. The finding in the
previous works that the loop effects can be drastic is reinforced: they play an
important role in the boundary conditions and non-perturbative geometry
deformation. One of the channels through which the quantum gravitational
effects enter is generation of the cosmological constant. The cosmological
constant feeds the time-dependence of a solution. We obtain a trans-Planckian
energy in the time-dependent case. The importance of time-dependence for the
trans-Planckian energy and black hole information is discussed.
