The simulation programs are important tools for analyzing different energetic options, including the use of energy efficiency measures and renewable energies. The objective of this study was to analyze comparatively the different computer tools available for modeling of solar domestic hot water systems in buildings. Among the main simulation software in use for this purpose, there are RETScreen International, EnergyPlus, TRNSYS, SolDesigner, SolarPro, e T*SOL. Among the tools mentioned, only EnergyPlus and RETScreen International are free, but they allow obtaining interesting results. In the presented case study can be seen the versatility of the RETScreen program, which allows for analysis of energy production, economic viability and carbon dioxide emissions. Within the range of computer solar water heaters simulators currently available, it is necessary that the user knows the tool specifications, such as programming language and capabilities so one may choose the program that is most suitable to produce the expected results for one's knowledge and modeling skills.
