This 1960s Vienna apartment was entirely renovated to meet the Passive House standard.
Successful application of Saint-Gobain's principles to build better resulted in improved thermal and acoustic comfort and the delivery of a constant supply of fresh, oxygen-rich air.
As well as saving on energy costs, the apartment – which now sports new windows, as well as a new kitchen and bathroom – has significantly increased in value.
Highlights and challenges
The aim of this project was to renovate a fourth floor apartment, located within a six-storey multi-family residential building, to achieve the Passive House standard – paying particular attention to insulation and acoustic performance.
