Blower door test of a housing unit

The rooftop dwelling was developed for industrialised housing constructions. Accordingly there has been strong focus on construction, assembling details as well as air tightness.

Cold bridges in constructions can result in considerable heat losses. In the rooftop dwelling the cold bridges between wall and ceiling, wall and floor etc. are sought eliminated by optimisation of the joint details keeping energy in focus.

Low air tightness in buildings will also lead to a considerable energy-consumption. In the dwelling there has been focus on a high level of air tightness so the heat losses caused by air leaking constructions are minimised.

The rooftop dwelling has air tightness equal to a natural air exchange of maximum 0.05/hour which is only 50% of the demands for a new building according to the new energy directives from 1 January 2006.

The industrial production process also means that it has been relatively simple to focus on air tightness and cold bridges.
