The Valencia Institute of Building (IVE) is a private, not-for-profit, foundation dedicated to improving quality and sustainability in the construction process through research and development. Based in Valencia, Spain, the Foundation has played since its creation in 1986 an important role in the self-regulation of the construction sector and the implementation of sustainability measures in the design, construction and use of buildings in Spain. In 2006, IVE- Certification Entity (IVE-EEE) was established with Governmental support to operate a voluntary certification scheme for new and existing buildings: Perfil de Calidad (PdC – Quality Profile).
