Sonnenhäuser weisen einen Primärenergiebedarf von maximal 15 kWh/m²a für Heizung und Hilfsenergie. In den gut gedämmten Gebäuden deckt eine Solaranlage typischerweise zwischen 60 und 70 % des Wärmebedarfs. Der Rest wird meist über eine Biomasseheizung abgedeckt. Der geringe Primärenergiebedarf ist bei den Sonnenhäusers (auch SolarAktiv-Häuser genannt) mit Mehrkosten für die Gebäudehülle und Anlagentechnik verbunden. Ein neue Tool, das am Fraunhofer-Institut für Solare Energiesysteme (ISE) entwickelt wurde ermöglich nun die Berechnung der erforderlichen Mehrkosten.

Power of the Sun. Dirt cheap   In a world hungry for energy, top scientist Michael Grätzel hopes to make solar cells more affordable by copying photosynthesis.   In the late 1980s, the German-born chemist Michael Grätzel literally tied his name to an invention that is hailed as a revolution in renewable energy.   Dye-sensitized solar cells (DSSC) - officially dubbed Grätzel cells to honour their creator - are transparent photovoltaic cells inspired by the way plants generate energy.
