The study presents the effects of the passive solar heating incorporated in an individual residential building located in Nis, brought about by the application of a passive solar system consisting of a sunspace and a thermo‐accumulative concrete wall thickness of 0.2 and 0.45 m. The building is not additionally heated by conventional fuels. A mathematical model was developed to investigate dynamic behavior of the thermo‐insulated building with attached sunspace and to investigate inner temperatures of the sunspace and of the room divided by thermo‐accumulative concrete partition wall with windows for direct collection of solar radiation. The diagrams are given for interior temperatures of the sunspace and of the room, taking into account the sunspace's various orientations: ψ = 0 ° (south‐orientated sunspace), ψ = +80° (east‐orientated sunspace), ψ = −80 °(west‐orientated sunspace). ψ stands for an angle that determines the position of the wall in relation to sunrays. The results shown in the study were derived using the mathematical model presented in the study. The highest room temperatures are achieved in the case of a thermo‐accumulative concrete wall with a thickness of 0.20 m for a south oriented building with sunspace (ψ = 0 °). This case requires the least additional heating by conventional fuels. The applied mathematical model can be used for the design and materialization of newly built buildings with attached sunspace. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13127, 2019
