In the course of DALEC an online concept evaluation tool for architects, building engineers, lighting designers and building owners was developed. Although easy to use, the software accounts for the complex thermal and light processes in buildings and allows a simple evaluation of heating, cooling and electric lighting loads. Not only energy, but also user behavior were considered (e.g. in terms of glare protection) and visual and thermal comfort were evaluated. This novel and innovative, holistic approach makes sustainable and energy efficient building design possible for new buildings as well as refurbishment.

ECC – EnergyCityConcepts – Development of a methodology and concept for the implementation of sustainable energy systems in cities by the example of Gleisdorf and Salzburg
In the context of this project two concrete model regions (small city Gleisdorf and urban city quarter Salzburg-Schallmoos) will be developed and tested with new methodical approaches (interdisciplinary urban and regional energy planning, modeling and simulation). An ambitious political commitment of both model regions is a 100% renewable or rather CO2-neutral energy supply.
Within the research project TFlex it was checked if the losses adherent to small district heating networks during low-load periods can be reduced. One possible solution is by deactivating the network and supplying the customers from previously charged decentralized storages. The optimal clustering of the storages and the possibility of solar-charging the storage were calculated with the aim of a guaranteed one-hundred percent heat supply.
Many traffic areas in urban environments are actually used as such only a small fraction of the time. Subject of this project was to investigate the possibility of using those areas by additional integration of photobioreactors for the production of biomass, integrating such systems to the maximum extent into the urban substance and energy cycles.
