Monitoring Sunhouse Eferding

In course of the monitoring project the effectiveness of the energy-technical system was checked on the basis of running measuring data. The data were evaluated and, if required, the arrangements and settings of the control system were adapted. Main result is that the energy balance could have been improved explicitly whilst the monitoring process.

Serial refurbishment for buildings in timber construction

Refurbishment of single- and two-familiy houses in timber construction in Austria has a large CO2-saving potential. To meet the special requirements for the refurbishment of timber constructions, a concept for the renovation to passive house respectively plus-energy house standard with special focus on ecologic construction materials was developed in this project.

The CircularFood project investigates the material and energetic cascading use of organic food residues from Austrian food production. The aim is to develop innovative processes for the extraction of high-quality protein components, liquid biofertilizers, organic plant substrates and peat substitutes in order to promote the circular economy and reduce CO2 emissions.

Earth movement: Clay - a climate- and resource-friendly building material

Manufacturing processes and transport of building materials are energy-intensive and cause high CO2emissions. In addition, many building materials pose a health and disposal problem due to their content of disruptive and harmful substances. Locally available clay can replace conventional materials if appropriately prepared and processed, and helps to save both manufacturing processes and transport routes.
