There is an emphasis in the energy rehabilitation of buildings and in the study and research of improvement measures aimed to make the building an NZEB (Nearly Zero Energy Building). The regulatory framework issued by the member states of the European Union, establish different objectives and provide methodologies for the calculation of energy performance, establishing minimum requirements for new buildings. This work addresses the implementation of the energy certification in a service building, applying the calculation methods to a case study. Improvement proposals are presented for the energy performance improvement that lead to a reduction in energy consumption. The purpose is to demonstrate that the proposed measures for the rational use of energy, outlined in the energy certificate, contribute to increased energy efficiency. These measures foster the reduction of energy consumption and consequently the reduction of greenhouse gases emissions.engEnergy EfficiencySustainabilityEnergy ConsumptionEnergy Certificationbook part10.1007/978-3-031-38165-2_106
