Renovation concepts for net zero energy buildings – best practice residential building Kapfenberg/Austria

Abstract

The high-performance renovation of the thermal envelope with prefabricated façade modules and with prefabricated modules for the building services represents a sustainable alternative to the established composite heat insulation system. In the frame of an Austrian research project(e80^3-Buildings – renovation concepts towards plus-energy building standard with prefabricated active roof and facade elements, integrated building services and grid integration; funded by the Federal Ministry for Transport, Innovation and Technology in the frame of the ‘building of tomorrow plus’ program; retrieved March 27, 2014, from http://www.hausderzukunft.at/results.html/id7005), the boundary conditions and the energy concept for a plus-energy building were developed. Furthermore, prototypes of prefabricated insulated façade modules and modules for the building services were planned, constructed and tested and afterwards implemented in an Austrian demonstration project. A comprehensive monitoring of the residential building is performed and quality assurance of the concepts and the implementation is introduced.
