Building energy codes must be considered to minimize the energy consumption of the residential sector. This paper aims to evaluate the evolution of the building energy codes of Spain based on energy simulation. A quantitative assessment of the residential thermal demand according to the new energy efficiency requirements introduced in national regulations over the years was performed. Heating, cooling, and domestic hot water demands were assessed for 60 cases modeled in DesignBuilder, combining different building geometric typologies, energy codes, and climate zones. Heating presented the largest contribution to the total energy demand reaching up to 75%. The codes’ evolution led to a significant reduction in heating and a slighter decrease in cooling. The results showed an average energy demand improvement of 50% from the first regulatory release to the latest one. info:eu-repo/grantAgreement/ES/MICIU-AEI-FEDER/RTI2018-098868-A-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.2 2022 ENGINEERING, MECHANICAL 79 / 136 = 0.581 2022 Q3 T2 0.436 2022 Aerospace Engineering 2022 Q2 Automotive Engineering 2022 Q2 Mechanical Engineering 2022 Q2 Engineering (miscellaneous) 2022 Q2 Industrial and Manufacturing Engineering 2022 Q2 Applied Mathematics 2022 Q3 4.0 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gesteira, Luis Gabriel Uche, Javier Universidad de Zaragoza (orcid)0000-0003-4408-6881 5004 590 Universidad de Zaragoza Dpto.
