In Spain, the construction sector has undergone significant changes over the last twenty years due to new ventilation standards driven by increased awareness of indoor air quality (IAQ) and energy efficiency, as well as environmental policies.
The Código Técnico de la Edificación (Building Code, CTE) has been the main regulation governing the quality of buildings since 2006, addressing all related aspects, including energy efficiency and IAQ. The CTE includes provisions aimed at promoting adequate IAQ in residential buildings, while also limiting energy demand across all building types.
Furthermore, it is worth noting that since 1998, the Reglamento de Instalaciones Térmicas de los Edificios (Regulation on thermal systems in buildings, RITE) has been setting the standards for IAQ in non-residential buildings.
It is important to acknowledge that both regulations are continuously evolving to keep up with advances in techniques and knowledge, as well as to ensure compliance with European Directives.
This paper is a summary of AIVCVIP 48.1 covering the following national trends:
- IAQ requirements and market,
- inspection of ventilation systems, and
- innovative systems and market.
