Facade Integrated Solar Collectors

Within the framework of this project system-, structural- as well as building physical basis theories should be elaborated, which will serve as a basis for constructional and aesthetically attractive solutions for the production of facade integrated solar collectors without thermal separation. The recyclability of the materials used and resource efficiency play a central role when it comes to the development of constructional solutions.

Based on the selection of suitable demonstration projects in Subproject 1 an innovative concept for passive and active building envelopes and energy supply of so called "Plus Energy Buildings" (renovation) has been developed.

Multi-Activ-Facade

Multi-Activ-Facade is a pre-manufactured, multifunctional panellised façade, which incorporates ventilation with heat recovery, passive house windows and photovoltaic for smart self-supply within retrofitting measures. The specific challenge is the application within social housing.

SpeedReg - Prompt quality assurance of the commissioning process of buildings

The focus of the project is on quality assurance within the commissioning process with the aim to speed up and to improve the operational adjustment of newly constructed or comprehensively renovated buildings. The fragmented know-how which is hardly accessible for the relevant target groups will be consolidated and elaborated in the form of a practice guideline which will be directly applicable in commissioning processes in practice. In this way the project contributes to the development of a common, well-established standard for quality assurance within the commissioning of buildings.

PEAR – Test facility for energy efficient automation and control of buildings

The energy demand calculated in the design phase often differs from measured values in the actual building operation. This projects reviews building automation and operation by presenting a solution how to assess energy efficiency of control strategies in the fields of air conditioning systems, concrete core activation and free cooling. The results are implemented in the demonstration building "Post am Rochus".

Passive cooling concepts for office and administrative buildings using earth-to-air and earth-to-fluid heat exchangers

Analysis of existing passive cooling concepts, examination of various other passive cooling concepts and a comparison with conventional air conditioning systems. The elaboration of practice-oriented tools for the planning and implementation of the passive cooling concepts selected.

ecoRegeneration: Development of a "Merit-Order" in order to assess regeneration heat for geothermal probes within urban residential neighbourhoods

In urban residential areas there are not enough active-cooled usages, to use the waste heat of the cooling process as required regeneration heat for geothermal probes; free cooling of the apartments is not sufficient. The project is developing various options (waste heat from commercial uses in the ground floor zones of residential buildings, by using waste heat of data centres, additional installation of heat generation systems for regeneration) within the urban settlement area, business models and is calculating life-cycle-costs of all solutions. The result should be a kind of "merit order" for regeneration heat.
