IMPACT OF THE CLIMATE CHANGE ON THE ENERGYCERTIFICATION OF A MULTI-FAMILIY BUILDING INVALENCIA

Resumen

The European EPBD directive initially emerged as a way to label buildings to inform
the consumer. At that time, it sought to compare its performance with other products, such as a
washing machine. However, the climatic, economic-social, and energy context is forcing the
evaluation of the actual energy performance with pecuniary links.
This article compares the actual Valencia weather in 1992, 2002, 2012, 2022, and 2023 with the
official one used by the Spanish certification scheme. An old, existing multi-family building is
rehabilitated to get a label A. Additionally, it meets the restrictions of the current CTE-HE. The
paper assesses the impact of considering the actual weather on their energy performance in both
states, before and after rehabilitation, as well as on their energy rating, and discusses the
outcomes. All computations have been performed with the recognized software tool CERMA.
