Seasonal Ground Solar Thermal Energy Storage – Review of Systems and Applications
Abstract
The building sector accounts for about 40% of the total energy use in the European Union (EU) countries (International Energy Agency, IEA 2009). However, at the same time the building sector has a documented cost-effective saving potential of up to 80%, which can be effected over the next 40 years. In order to ensure these considerable energy conservations and at the same time to apply renewable energy in an optimal way, the development of integrated, intelligent technologies for buildings is needed.
