Key project: e80^3 – Buildings
The retrofit concept is based on energy efficiency measures (highly insulated, prefabricated active energy roof and energy facade elements with built-in building service units), on a high ratio of renewable energy sources and on an intelligent integration of energy supply in heat and electric power networks. The concept contributes significantly to the achievements of three […]
Oekosan´09 – International symposium for high-quality energetic renovation of large-scale buildings
Starting point / motivation A major part of the energy consumption of the member states of the European Union is consumed by the building sector. Especially in the Central-European moderate climate zones nearly one third of the total energy consumption is spent on space heating. In the field of building renovation the potential savings for […]

Compact Thermal Energy Storage: Material Development for System Integration (IEA SHC Task42 Storage-Materials)
This task deals with advanced materials for latent and chemical thermal energy storage, and excludes materials related to sensible heat storage. Sensible materials for heat storage are only used as reference cases. The task deals with these materials on three different scales: The project is organized in a matrix-like structure and is divided in the […]
SOLTRAIN
The overall goal of this southern African regional project is to contribute to the switch from a fossil fuel based energy supply to a sustainable energy supply system based on renewable energies. This should be achieved by building up training capacities in the participating countries in the field of solar thermal technology and the improvement […]
PEP – Promotion of European Passive Houses
Ziele und Inhalte: Ziel des Projektes PEP war es, den Marktanteil von Passivhäusern deutlich zu steigern. Österreich konnte als einer der Themenführer in diesem Bereich dazu einen wesentlichen Beitrag leisten. Dies passierte durch Know-How-Transfer in die neuen europäischen Passivhaus-Märkte, sowie durch gezielte Aktivitäten in Österreich. Besonderes Augenmerk wurde dabei auf die Nutzung von Synergieeffekten mit […]
IEA – ECBCS Annex 50 – Prefabricated Systems for Low Energy Renovation of Residential Buildings
A really conservation of energy is only in existing buildings possible. The fraction of the total energy consumption for new buildings is in most of the industrial countries only about 10-20%. 80% is allotted to the existing buildings. The topic “sustainable retrofit for residential buildings” is for this reason also of high importance in a […]
NZEB – Towards Net Zero Energy Solar Buildings
The “Net Zero” – Option While “net zero” or “plus-energy” concepts are already widely used for marketing purposes all over the world an international harmonized definition and methodology is missing. A key issue is the (superficial) simplicity of the concept, which turns to be a big challenge: The first strategy is to reduce energy demand […]
KeepCool II – Transforming the market from “cooling” to “sustainable summer comfort”
Das Vorgängerprojekt „KeepCool“ fokussierte besonders auf nachhaltige Kühltechnologien und die Beschreibung von „Best Practice Beispielen für Bürobauten und andere öffentliche Gebäude. Das Nachfolgeprojekt „KeepCool II“ wird die Inhalte und Erfahrungen aus dem ersten Projekt erweiten. Das heißt, die Hauptschwerpunkte des Projektes liegen in den Verbreitungsaktivitäten, das bestehende Material zu überarbeiten und zu erweitern und gute […]
CombiSol
As the market share of combisystems is increasing in most of the European countries but is nevertheless quite small, CombiSol will encourage an accelerated growth in the share of heat produced by solar energy and will promote the quality increase, by tackling some non-technological barriers, thanks to:
