This thesis delineates how the process of "certified rehabilitation" can be applied by the architect to acquire tax savings and quality control on the rehabilitation of a historic building. Theory and principle are applied to a specific case. To strengthen the architect's and the planner's awareness of governmental guidelines, approaches are suggested to benefit the client and improve the potential for "adaptive reuse" with emphasis on lighting. This thesis shows, by example, how economics and building methods can enhance Historic Preservation.
