Abstract: The availability of tools capable of performing pre-feasibility studies of Solar Heat for Industrial Processes (SHIP) projects in a fast, precise, and low cost way has become necessary for the acceptance of this technology by the industrial sector. The tools that have emerged so far are very heterogeneous, making it difficult to benchmark projects. The significant disparity in the toold limits the commercial development of the technology by generating uncertainty in project promoters and financial entities. This work presents a methodology to unify the efforts that are being carried out for the development of these simulation tools. The proposed methodology combines the use of open and proprietary source. In this way, open source development is maintained by universities and public / private centers, while private companies still keep any sensitive information private.
