The Commission is in the process of updating some of the content on this website in light of the withdrawal of the United Kingdom from the European Union. If the site contains content that does not yet reflect the withdrawal of the United Kingdom, it is unintentional and will be addressed.

The European Commission released today a set of legislative measures related to the energy sector, referred to as the Winter Package. Most notably, it contains the revised Renewable Energy Directive (RED), the Energy Efficiency Directive (EED) and Energy Performance of Buildings Directive (EPBD). Together, they constitute the legislative pillars underpinning the EU renewable energy sector.

Solar houses have a primary energy demand of maximum 15 kWh/m²a for heating and auxiliary. A thermal solar plant covers typically between 60 and 70 percent of the heat demand. The remainder is usually generated by a biomass boiler. The low primary energy demand of the solar houses (in German “Sonnenhäuser” or “SolarAktiv-Häuser”) is linked to additional costs at the building envelope and the building services systems. A new tool, developed at Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE), allows now the calculation of the necessary additional costs.

This report, prepared within the framework of the Solar Heating and Cooling Programme (SHC) of the International Energy Agency (IEA), presents solar thermal market data from 61 countries covering an estimated 95% of the worldwide market (the remaining 5%of the market were extrapolated and are labelled as “all other countries”). These data were collected from a survey of the national delegates of the IEA SHC Programme’s Executive Committee and other national experts active in the field of solar thermal energy.

This guide, released by the Zero Carbon Hub, is a step-by-step guide for small and medium-sized enterprises (SME) housebuilders on building energy efficient homes cost effectively. It begins with highlighting high areas of cost risk when building a low energy home and focuses specifically on photovoltaics (PV) and solar thermal, wall insulation, heating, airtightness and ventilation, thermal bridges and orientation.

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.

Aufgrund des hohen Erfolgs der vorangegangenen Jahre wurde das Förderprogramm „Demoprojekte Solarhaus“ für 2016 neu aufgelegt. Dabei kann eine Investitionsförderung von bis zu € 17.000- für den Neubau oder die Sanierung eines Ein- oder Zweifamilienhauses beantragt werden. Den Zuschuss gibt es zusätzlich zu den verfügbaren Landesförderungen.

So far seasonal storage systems, mostly realised as hot water storage systems, had to be rather large in order to use summer heat for heating during the winter. Smaller storage systems tend to cool down too quickly. Therefore seasonal storage systems are mostly applied for housing estates or large consumers. Within the SolSpaces project, scientists are developing and testing a new solar heating system including an evacuated tube air collector and a thermochemical heat storage system to store solar heat for the use in winter.

Bisher waren saisonale Wärmespeichersysteme (meist ausgeführt als Warmwasserspeichersystems) sehr groß, um die Nutzung von sommerlicher Wärme in der Winterzeit zu ermöglichen. Kleine Speicher kühlen zu schnell aus. Deshalb wurden solche saisonalen Speicher auch meist in Siedlungen oder für Großverbraucher eingesetzt. Im SolSpaces-Projekt des ITW der Universität Stuttgart entwickeln und testen Forscher ein neues solares Heizsystem das Vakuumröhren-Luftkollektoren mit einem thermochemischen Speicher koppelt.
