  According to the principle of emergence, the expansion of the universe can be
explained as the emergence of space with the progress of cosmic time. We have
analytically solved the equation of emergence proposed by Padmanabhan by
assuming the Komar energy density $\rho+3P$ as a function of the Hubble
parameter. The resulting model describes the evolution of the universe, which
proceeds towards a final de Sitter state. Model parameters have been extracted
using the cosmological observational data. Further, the horizon entropy
evolution of the model has been studied. The model predicts a universe having a
transition from a prior decelerated epoch to a late accelerated epoch and
reasonably predicts the cosmological constant.
