Economic usage of Photovoltaic electricity in buildings
The aim of this project is to optimise the direct usage of PV-electricity produced in buildings. The main question concerning the right dimensioning of the PV generator should be answered in order to achieve a high direct usage rate of produced PV electricity under economic considerations. This analysis will be carried out for various building categories. As result, a calculation method will be developed (incl. report), in order to achieve the optimal, most economic PV system for various building categories and user typologies.

Excess heat has the potential to further grow to become an important part of the energy puzzle. Up to 25% of district heating could be covered by industrial excess heat and more than 10 % of the EU's total energy demand for heating and hot water could be covered by heat from data centres, metro stations, service sector buildings, and waste-water treatment plants.
Building as living lab - Buildings as a living lab for climate-neutral, needs-based and affordable housing

By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.
DiRecT – Direct recycling and upcycling of titanium chips
In the project DiRecT, different new technologies will be developed and evaluated which make it possible to directly recycle the chips generated in the manufacturing process of high-quality titanium products or to produce directly from the chips near-net-shape components or improved semi-finished products (upcycling).
P2H-Pot - Potentials, economic feasibility and system solutions for Power-to-Heat
P2H-Pot has identified economically feasible potentials for Power-to-Heat (P2H) in urban regions. The suitability of different technical system configurations were investigated using thermodynamic simulation and considering experiences from Scandinavian cases. The assessment of short, medium and long term relevance and economic feasibility of P2H were accomplished by simulating model-based scenarios up to 2050 of the Austrian and German electricity and heat market. In cooperation with a district heating company three case studies have been carried out.
Development of foamed products based on protein
An extrusion process is applied for the production of foamed profiles and filling materials consisting of biogenous raw materials. Pellets can be used as insulation material in the building industry, profiles shall break into new markets because of its little weight.

RAARA - Residential Area Augmented Reality Acoustics
Populations with high exposure to noise emissions will generally agree: Noise means trouble. The aim of project RAARA is to develop a simple, intuitive albeit accurate method for reducing noise imissions in urban areas. This method involves placing a noise-source into its planned real-world destination prior to actual installation, by means of augmented reality. The ensuing sound-imissions are then made tangible by means of sound effects and coloured visualizations. This exceptional approach will facilitate planning for heating and cooling devices and thus reduce noise pollution in urban areas. This, in turn, can contribute to an increase in societal acceptance and investment in renewable energy.
