A parametric study of the energy and moisture performance in Passive House exterior walls
(2011) 4th Nordic Passive House Conference, 2011- Abstract
- Adding insulation to improve the energy performance of a building with a traditional Swedish wooden construction may increase the risk of mould growth in the wooden construction.
There is a need to address this potential problem since the amount of passive houses and low energy buildings are increasing as a means to reduce energy use, energy dependency and greenhouse gas emissions.
This paper evaluates energy performance and moisture performance simultaneously in order to create a more holistic approach. Space heating demand, peak load for space heating and risk for mould growth are evaluated.
The analysis of these three different aspects shows that there is no contradiction between moisture safety design and...

There is a need to address this potential problem since the amount of passive houses and low energy buildings are increasing as a means to reduce energy use, energy dependency and greenhouse gas emissions.
This paper evaluates energy performance and moisture performance simultaneously in order to create a more holistic approach. Space heating demand, peak load for space heating and risk for mould growth are evaluated.
The analysis of these three different aspects shows that there is no contradiction between moisture safety design and energy efficient design. It may however not be suitable to increase the amounts of insulation in traditional wooden constructions without considering risk of mould growth. (Less)
