Abstract

Urban agglomerations are growing rapidly worldwide. Building additional living quarters has to be complemented by refurbishment and urban densification actions. In this context, attic extensions offer a high potential to increase urban density. At the same time, modern refurbishment projects have to improve the living comfort and energy efficiency of our buildings. The objective of the research project 'Attic Adapt 2050' is the development of a low cost, lightweight attic-extension-system, applicable to a great number of buildings of the same construction type. Its primary goal is the creation of a timber-based, industrially prefabricated system with integrated renewable energy components and a highly efficient thermal envelope. Vienna's social housing buildings from the 1950s - 70s provide both an uniform building typology and low density - offering a high potential for ecological and economical urban development. Due to the typological design of post-war residential buildings, the described system can be adapted to many similar building types across Europe. It thus provides a suitable and low cost solution for highly efficient refurbishment and densification in Vienna - and elsewhere.
