Use of waste heat and covering of the remaining energy demand by the renewable energy sources hydropower and biomass in a metal-processing company.
Application of the Stirling cycle for environmentally compatible cooling - systems analysis
Conventional cooling has adverse effects on environment (eg. ozone depletion, global warming). One option for environmentally compatible cooling systems for near ambient temperatures (-10 to -50°C) is the Stirling cooler with environmental friendly process.
Ecologically friendly resin impregnation of rotating machines with the use of the joule effect
Windings of rotating machines or electrical generators (e. g. wind and water power generators) are impregnated with resin. A new technology using the heating effect of current is investigated. The high efficiency of heating with the joule effect results in quick heating of stator leading to fast gelling of the resin, which implies low emission.

Strategic optimisation of the regulation of air moisture through ventilation systems to reduce energy demand for humidifiers and dehumidifiers
For the validation of coupled room and building component simulations, an analytical solution of this unsteady problem was developed. Finally, a simplified method for determining the humidification and dehumidification demands considering a room's effective moisture capacity was developed.
Contracting Platform for SME´s
Evaluation of requirements and framework conditions for the implementation and the operation of a Contracting Platform for SME´s in Austria for the cost efficient identification and realisation of energy efficiency measures.
Energy Performance Contracting (IEA DSM Implementing Agreement - Task X)
The objective of this task within the IEA DSM programme is to facilitate the use of performance contracts and other energy service company (ESCO) contracts. In this scenario, the ESCO has taken on the project's performance risk by guaranteeing a specified level of energy savings. Its compensation for this risk is directly tied to achieving savings. The financing for such a project could come from the ESCO, the equipment supplier or a third-party company.
Sustainable energy supply for Austria
Rapidly increasing energy consumption and decreasing resources of fossil fuels lead to dramatical economical, ecological and social problems.This study identified the feasible long term potential of renewable energy sources. Then ways were developed how to supply the demand for future energy consumption with renewable energy sources, despite increasing energy services.
