Effect of Shielding Object to the Specific Heat Demand for Heating of a House

When designing energy-efficient homes and buildings especially in the passive standard is needed to efficiently utilize solar heat gain in the winter and orientation of glazed surfaces on the sunlit side. But it is also necessary to prevent overheating of rooms in the summer. This can be achieved by choosing the correct shielding of windows or whole building. In evaluating of energy intensity, however , the methods of shading adversely affect the final annual heat demand for heating the building. This is fundamentally influenced by the correction factor Fsh. This can be determined simply or by calculation in accordance with CSN EN ISO 13790. The aim of this article is to determine what effect has the calculation of the correction factor to calculate the specific heat for heating for an example of 2 houses in passive standard in comparison with its simplified purpose.
