Decarbonization and IAQ in Spain: a roadmap

The presentation provides a brief overview of the current situation and a roadmap for decarbonizing the building stock under the context of EU directives. It also discusses how it could be implemented into Spanish building regulations. It examines the evolution of energy and emissions indicators and how they can help tackle the electrification of uses, generalized on-site energy generation, energy storage or building interaction with the grid. Several aspects of indoor air quality are involved in these challenges, including the increasing share of energy use due to ventilation and infiltration as well as the greater prevalence of energy recovery and free cooling capable systems. Further, additional questions arise from the differences in the scenarios used for energy efficiency and IAQ evaluation.
