The purpose of this paper is to show the timing of an energy allocation pattern to Hoffman's fifteen demand sectors satisfying an optimal strategy of the Haefele-Manne model. More specifically, a linear programming optimization problem will be solved year by year by using the mathematical technique of the Hoffman model. The problem is characterized by: 

(a) the upper bound of energy supply of the individual supply alternatives fixed by an optimal solution of the Haefele-Manne model. For an illustration, the model society 1.60 is chosen; and 

(b) the lower bound of energy demand of the individual demand sectors fixed for each year, 1997, 2000, 2003, 2006, and 2009 in accordance with the demand projection of the Hoffman model.
