Jordtäckta hus
Energiberäkningar och kostnadskalkyler på ett jordtäckt hus i Malmö
With rising energy prices and the threat of climate change, energy costs and energy savings havebecome a central and important part in building. Therefore it is interesting to explore different andnon-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 toreduce the maximum power demand. The aim of this study was to construct a house in Malmö and seeif Earth sheltered houses can be a cost effective alternative for the construction of sustainable andenergy-efficient houses.Previous studies have shown that Earth sheltered houses have reduced their power requirement with upto 25% and their use of energy with 10%. Numerical calculations in Comsol Multiphysic 4.2, wasperformed on a house with different degrees of earth covering. Thereafter, additional investmentsbecause 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 energyprice were made. The study shows that it is profitable with Earth sheltered houses and that a 10 cmthick layer of earth on the roof is the optimal amount.
