With a focus on high-rise buildings, the Cost-Effective project has developed new façade components in addition to business moels and technical concepts and has demonstrated these concepts in two pilot buildings. It aims to help achieve demanding energy reduction targets. Within this project
- developed a set of 5 of new façade components and systems:
- a glazing integrated transparent solar thermal collectorair
- heating vacuum tube collectors for façade application
- an angle-selective transmittance BIPV-component
- a facade integrated natural ventilation system with heat recovery
- a solar assisted decentralized heat pump system using unglazed solar thermal collectors with plaster covering
- developed integrated (techno-economic) concepts consisting of technical concepts and corresponding business-models for the most important categories of existing high-rise buildings in Europe (EU25). This includes also the identification of the most important categories of existing high-rise buildings.
- demonstrated the practical feasibility in two pilot buildings in Spain and Slovenia. The Slovenian pilot building has been added to the project within the within the project lifetime in order to be able to demonstrate more of the new technologies.
