MULTI COMFORT design principles can be applied to any type of building (residential or non-residential, new build or renovation project) in any country or climate around the world.
This 1960s Vienna apartment was entirely renovated to meet the Passive House standard.
Successful application of MULTI COMFORT principles 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.
