Abstract
Issue:
With today's increasingly stringent demands for reduced energy consumption for buildings, many choose to build so-called low-energy or passive houses. These houses have that in common that they are well insulated and advantageous from an energy perspective but alongside this more prone to moisture damage. In this work, a passive house was designed and energy calculations were executed. The house's basic, wall and roof constructions were evaluated from a building physical point of view.

Purpose:
The purpose of this study was to find a solution and design a new Swedish passive house that met FEBY12s requirements. The different construction elements must also be moisture proof. The one-family house is projected for one family... (More)

Purpose:
The purpose of this study was to find a solution and design a new Swedish passive house that met FEBY12s requirements. The different construction elements must also be moisture proof. The one-family house is projected for one family will be designed as rationally as possible for the building to be economically advantageous.

Main questions:
Is the house’s construction suitable from energy perspective?
Is the house’s construction moisture-proof?

Method:
Work began by literature studies in the subject were books, scientific articles and relevant websites have been the basis for learning. Subsequently architectural drawings in Revit were made. The house's energy consumption and moisture safety was simulated and calculated in WUFI Plus.

Conclusions:
From the energy meets the house FEBY12 requirements and thus the name "Projected Passive House according to FEBY 12". Passive house's total specific energy demand is expected to be 49,3 kWh/m²A_temp.

The house’s wall-, roof- and foundation design is therefore suitable from the energy perspective because all the energy requirements were met.

From a moisture standpoint the solution with a diffusion close paper in the roof structure is at risk for mold growth. If a roof with a diffusion open roofing felt is elected may the houses construction be considered as moisture-proof. The house's basic- and wall construction is deemed to be moisture-proof (Less)
