This conference was held July 27--28, 1994 in Moscow. The main purpose of the meeting was to implement an agreement between the Russian Federation and the US to facilitate cooperative research on health and environmental effects of radiation. It was hoped that the exchange of information would provide a good basis for employing new scientific knowledge to implement practical measures to facilitate the rehabilitation of radioactively contaminated areas and to treat radiation illnesses. The Russian Federation suggested five main scientific areas for cooperative research. They will prepare proposals on 4--5 projects within the scope of the scientific areas discussed and forward them to the US delegation for consideration of the possibility to facilitate joint research.

DER-CAM Developed by the Lawrence Berkeley National Laboratory (LBNL), is an optimization tool for DER technology selection. However it can not be simply applied to the Japanese case because of the different climate and the utility tariff. This research aims to develop an optimization tool for distributed energy for Japanese buildings using GAMS, a high-level modeling system for mathematical programming and optimization. This paper describes how we apply and demonstrate the tool to the energy center at Kitakyushu Research city, where has installed a fuel cell and a gas engine. An analysis has also been conducted to see how the utility tarriff and the equipment efficiency can affect the operation of the DER system.
