The design aims not only at creating comfortable living spaces and practical work environments, but at connecting these realms, thus providing a holistically attractive “living space”. A pilot project will be built on an appropriate site in the very core of Moosburg, neighbouring both the village square and the educational campus.
Exemplary transformation of a traffic abused open urban structure. The target was to develop a model through supplementary housing as well as social measures and measures for the surrounding.

In this study approaches of low-tech buildings were examined and particularly innovative and representative concepts were documented in detail. The aim was to elaborate the current state of the art and the existing know how and knowledge on the basis of realized examples as well as to show potential for further development.
lowTEMP4districtheat - Reduction of the system parameters of heating networks for the integration of renewable heat sources using soft sensors
Analysis of the use of soft sensors in addition to selective real measurements for the complete recording of real-time parameters of heating networks. The data obtained enable detailed grid simulations with low computing power requirements and form the basis of a strategy for lowering the grid temperatures and feeding in decentrally generated heat.
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.
The objective of this research project is to design a methodology for developing data and process models and to apply them by modelling selected MEP systems. A particular but not exclusive focus is put on the renewable heating technologies, e.g. heat pumps, solar heat and biomass as well as ventilation systems. The data and process models developed in this research project will be scientifically evaluated in two pilot projects. The models, the approaches taken during development and the project team’s experiences with the pilot application of the models will be disseminated openly.
A robust, predictive controller which utilises weather forecast data to control thermally active building systems had been designed, researched and assessed in terms of energy efficiency and comfort compared to standard controllers, especially for cooling purposes. Simulations and real measurements using two "Test-Boxes" with thermally active building systems which are constructed and built for this purpose were used to analyse energy efficiency and comfort. Low complexity and transparency of methods and solutions should allow for transferability of all results to guarantee maximum usability for similar applications.
This study uses several data sources to analyze the effects of the research programe "Haus der Zukunft" ("Building of Tomorrow") on the Austrian housebuilding industry and the built environment.
This project addressed the development of construction details for the implementation of vacuum glazing panels in new windows. In this project such constructions (form of frame, thermal bridges, structural aspects, mounting of glass) were explored via empirical experiments and via simulation. As an outcome, a mock-up was constructed, and the findings were documented in a comprehensive document.
In the frame of the project a classification system for Smart City Technologies had beed developed, the relevance of a wide range of technologies in terms of their potential contribution to the development of sustainable and more resilient cities with a high quality of life had beed evaluated and a comprehensive classification of the technical maturity of relevant technologies, technical (sub-)systems and technology-related services had been given.
OEKOPLUS-KOMPLEX - Analysis of the technical, economical and ecological preconditions for the establishment and utilisation of plus-energy-buildings and building assemblies
The evolution of the low energy house and the passive house standards to the plus energy standard results in a clear reduction of green house gas emissions as well as the primary energy input. The goal of the project was the determination of the technical, ecological and economic basic conditions for the construction and the use of "plus-energy-buildings" in order to finally realize them.
The primary research topic of OPEN HEAT GRID was to investigate the possibilities of enforcing the feed-in of industrial waste heat into existing district heating networks. The project results show that excess heat is not for free: despite minimal variable costs, the investment costs need to satisfy usual payback periods. The analysis shows that there is no need for a regulation in the sense of a feed-in obligation or market liberalization. However, from an economic point of view, information asymmetries exist, which may lead to irrational decisions.
How much energy does a passive house actually save? Does a passive house pay-off by itself? What are the costs for maintancence? For the first time an approximation for the running costs of a passive house were systematically documented and compared.
OttoWagner-ArealPlus - Feasibility study for a certified plus-energy-district-renovation of the listed Otto-Wagner-Area
Development of an innovative concept for the transformation of the Viennese Otto-Wagner-Area into a plus-energy-quartier while meeting requirements of cultural heritage management. The historic architectural jewel covers an area of around 50 hectares, consists of 70 buildings and a gross floor area of around 200,000 m². The solution meets highest energy efficiency standards and comfort requirements.
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.
With the city of Leoben as a use case this exploratory project will, for the first time ever, examine the spatial effects, synergy- and energy potentials of newly developed wide-span light-weight solar canopies for streets and squares in urban public space as well as their implications on the townscape, the image of the city and the city function.
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".
Analysis of different options for the use of industrial surplus energies of various shapes (waste heat, waste water, waste) and renewable energy sources in the industrial sector (e.g. solar panels on roof surfaces) in adjacent urban areas, which act as an "energy sponge". Based on real consumption and availability data, a simulation model was created and opportunities for synergies were documented.
The passive house standard and energy-efficient building technologies are getting increasingly important for office buildings, too. However, standardisation is not completed on the same level as known from the residential building sector. The project at hand brings in definitions and makes a suggestion on a standardised calculation method for office buildings in passive house quality.
Piezo-Klett: Development of piezoelectric hook-and-loop application for the energy supply of active sensor technology in the building industry
The present project considers buildings, parts of buildings and their joints (component nodes) as energy generators by using the hook-and-loop fastener in combination with the piezoelectric effect to perform a so-called energy harvesting.
