The high costs that energy has reached entails the danger of not being able to maintain the houses at an adequate temperature in the cold months. An economic and thermally feasible response to these situations is the inclusion of natural air conditioning systems in the spaces of homes. Strategies and conventional passive heating systems, such as direct gain, Trombe walls or greenhouses among others, that take advantage of solar thermal energy can raise the interior temperature of the spaces to reach thermal comfort levels. However, there are spaces that do not allow the inclusion of these systems because they are without facades oriented towards Ecuador. In this context, a passive solar radiant heating system called SIRASOL has been developed. The objective of the work is to evaluate the comfort conditions and the potential for energy and economic savings with the use of SIRASOL in single-family homes in the provinces of the Argentine Republic: Mendoza , San Juan and La Rioja, through mathematical analysis and Energy Plus simulation software. Based on simulations with the Energy Plus software of a home with and without the use of SIRASOL, an increase of 5 ° C of the operating temperature was obtained, with an energy saving of 14.6% and 84% of comfort users. . Extrapolating the energy savings of the homes of these provinces, it is noted that saving has two sides. a- INDIVIDUAL: the user will consume less energy, and b- SOCIAL: every 28 homes that the state builds, it will be possible to build another house considering the economic savings that implies.
