Manage_GeoCity - Development of a method for the coordinated management of geothermal energy in urban areas

Based on the urban region Graz a method had been developed for the coordinated use and management of shallow geothermal energy for heating and cooling as well as seasonal heat storage in urban regions. Ground water flow, different geologic conditions, heating and cooling demand, heat input from solar collectors and industrial waste heat and the possibilities of seasonal heat storage in the subsurface were considered.

ProKlim - Optimisation of Energy Efficiency of automated indoor climate systems by using weather forecasts

Investigation of the basic energy savings potential for buildings in commercial use by including weather forecasts as a variable. Additionally, a concept for integrating weather forecasts into the heating and air conditioning control systems in buildings is planned to be developed. Within the scope of the feasibility study, a detailed analysis of technological possibilities, including both hardware and software, will be conducted.

Transferproject: Professional strawbale building - "Virtual building-site", exhibition and instruction material

Strawbale-workshops are considered as the best way to inseminate this ecological building-technique. The "virtual building site" has some decisive advantages over the common situation: it does not depend on the weather, allows the comparative study of different constructing methods and can, as a permanent installation, be used as an exhibition.

StromBIZ - demonstration projects: business models for decentralized electricity generation and distribution

Feasible business models to utilize locally generated renewable energy are expected to induce a tipping point for the "Energy Turnaround" in Austria. Within the proposed project a number of demonstration PV plants on residential and non-residential buildings had been realized. On this basis new approaches of business cases had been developed, implemented, tested and disseminated.

"gugler! build & print triple zero" - subproject 2: building with recycros

Building with recycros is working out basics in order to close the cycle of materials in the building sector as well as to increase the usage of recycled materials (recycros). The existing material cycles in the building sector are going to be analysed. Furthermore, there will be a catalogue presented, covering the actual situation of which materials are used in today´s engineering and how the waste is treated. The project will be completed with a summary of results and a proposal of concrete materials and constructional systems for the building project gugler.

Gründerzeit with future - subproject 5: Documentation and monitoring

The main aim is the documentation and monitoring of the demonstration projects within the scope of the project "Historical buildings of tomorrow" with regard to the technical implementation, investment and operation costs and to the energetic performance. All demonstration projects will be accompanied by an evaluation process regarding occupants' satisfaction and the refurbishment process. Beyond that, legal constraints for innovative refurbishment of historical buildings will be documented and proposals for adaptations of the rental law and refurbishment subsidy schemes will be developed.
