dc.description.abstractPassive solar gains via accumulation and heat transfer through the building envelopes are inherent to all buildings. The amounts of the solar energy utilized in this way, depend on the geographical locations, the structural designs of the building elements, their spatial orientation and the used materials. European and national regulations contain methodologies for determining solar gains through transparent and opaque building envelopes. They are used in the thermal balances of buildings at determining the required energies for heating and cooling. However, passively utilized solar gains through the building envelopes are often neglected in the public space. For example, they are not included as required renewable energy (RE) at the established practice of energy audit and energy certification of the buildings, which is generally incorrect. This work proposes guidelines for easy computation and counting of the passive solar gains in the energy consumption mix of the buildings. Applications of the guidelines for various buildings in the Seventh climate zone of Bulgaria have been demonstrated. It has been proven that the accounting for passive solar gains as energy consumption results in increasing of RE proportion in the supplied energies in the buildings.
