With rising energy prices and the threat of climate change, energy costs and energy savings have
become a central and important part in building. Therefore it is interesting to explore different and
non-conventional methods of energy conservation. Building Earth sheltered houses is such a method.
Earth provides good insulation and provides the ability to both reduce the total heating needs and to
reduce the maximum power demand. The aim of this study was to construct a house in Malmö and see
if Earth sheltered houses can be a cost effective alternative for the construction of sustainable and
Previous studies have shown that Earth sheltered houses have reduced their power requirement with up
to 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, was
performed on a house with different degrees of earth covering. Thereafter, additional investments
because of the strengthened structure to accommodate the weight of the earth have been made.
Subsequently, a number of economic calculations performed for various scenarios of future energy
price were made. The study shows that it is profitable with Earth sheltered houses and that a 10 cm
thick layer of earth on the roof is the optimal amount.
