To limit the probability that the energy model will not appropriately account for the solar absorptance of the finishes (which could change during the permit acquisition process) on exterior walls, roofs and exposed floors of the proposed building, which could lead to inaccuracy of the model, which could lead to overestimation of the energy used by the reference building or underestimation of the energy used by the proposed building, which could lead to excessive use of energy, which could lead to an unacceptable effect on the environment.
