The method of supplying the electric power and heat energy for the energy demand of buildings by Centralized system type and distributed system type of fuel cell network is studied. The hot-water piping route planning program of fuel cell network was developed by using genetic algorithm based on the view of TSP ( Traveling salesman problem) . In this program, the piping route planning which minimizes the quantity of heat loss in hot-water piping can be performed. The residential section model of Sapporo city of 74 buildings was analyzed, and the quantity of heat loss from the hot-water piping of both systems was estimated. Consequently, the ratio of the quantity of heat loss of a distributed system to a centralized system was about 50% in the full year average. This program is introduced into the route planning of hot- Water piping system of the fuel cell network, and plan to reduce the quantity of heat loss in a distributed system will be made.
