To this end, a virtual building was defined and multiple designs were evaluated using DesignBuilder software. A set of 170 alternative scenarios was established and parametrically evaluated for five cities representing the five <a class=\"topic-link\" title=\"Learn more about climatic zones from ScienceDirect's AI-generated Topic Pages\" href=\"https:\/\/www.sciencedirect.com\/topics\/earth-and-planetary-sciences\/climatic-zone\">climatic zones<\/a> of inland Spain (Bilbao, Burgos, Seville, Madrid and Almeria).

The great potential of <a class=\"topic-link\" title=\"Learn more about photovoltaic from ScienceDirect's AI-generated Topic Pages\" href=\"https:\/\/www.sciencedirect.com\/topics\/engineering\/photovoltaics\">photovoltaic<\/a> energy is highlighted, which allows negative values to be obtained for the two Equivalent Uniform Annual Costs due to the cost avoided through self-consumption.
