Simulation programs are an important tool to reduce building energy demands. However, there are difficulties that limit the use of these applications including the understanding and interpretation of the results. Due to the uncertainty regarding the reading and interpretation of results leading to design decisions, we propose a graphical display analysis, both scientific and information, charts, tables, diagrams, etc. Which apply to both energy simulation tools as complementary programs. It seeks to establish what tools have the greatest impact in the analysis process and how it influences the design decisions.
