At the development "residential Passive House Utendorfgasse" were reached very low building costs. Would there be different building costs by using ecological materials and technologies? There will be calculated additional and reduced costs by using the ecological building-catalogue and internal characteristic values of projects that are similar in design.
CHALLENGE - Highly efficient use of hot gas and waste heat in air/water heat pumps for plus-energy buildings and quarters
CHALLENGE aims to further develop the system concept for air-to-water heat pumps in such a way that they can be used efficiently and without the above mentioned negative effects in densely built-up urban areas. In concrete terms, validated simulations and a functional model of the overall system on a laboratory scale are to be used to demonstrate that the concept can save 10% of electrical energy, reduce the noise of outdoor units in summer to a minimum and prevent the formation of local heat islands.

Development of systems for the emission-neutral cooling of office, research and urban quarters on the basis of photovoltaic or geothermal energy supply and user integration. Life cycle cost calculations and analyses of grey and operational greenhouse gas emissions allow a holistic assessment.
CoolAIR - Predictive control of natural nighttime ventilation and daylight-optimized shading for passive building cooling
Natural nighttime ventilation and daylight-optimized shadowing are high potential approaches to efficiently and economical cool buildings. Nevertheless, the full potential cannot be acquired, since, if at all, such behavior is manually initiated by users. Goal of this project is the development of an automated, self-learning system that can assess the full cooling capabilities and establish an alternative to conventional air conditioning systems.
In the present project an absorption chiller will be adapted to meet the specific requirements necessary to integrate it with the CHP unit. By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.
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.
Development of a cost-benefit-tool which reaches beyond a pure cost approach and also recognizes the benefits of a building for its inhabitants and users. The inclusion of benefits is based on existing evaluation systems, especially on the Austrian building evaluation system TQB - Total Quality Building, which has been revised in 2009.
Development of a strategy for industrialized serial production of ecological passive houses made out of renewable resources
Development of a strategy for industrialized seria. production of ecological passive solar houses made out of building materials based on renewable resources as foundation for the dissemination of sustainable solutions for the production of prefabricated houses and of single houses.
What are the impacts of the digital transformation of the Austrian construction industry on this sector’s labour market? By looking at the next five to ten years it will be analysed whether and to what extent digital applications lead to an increasing, falling or stagnant demand for employees in the construction industry and in construction occupations.
Digitalization in Urban Planning: From Spatial Energy Planning to Digitalization in Construction Engineering (PBM_integrativ)
The project provides a comprehensive overview of conditions and interrelations between administration, economy and planning and to elaborate the most important features and deficits in the flow of relevant information between the different phases of a building’s life cycle - planning, construction and management/administration.
E_PROFIL is a set of methods (an IT-supported toolkit) for the elaboration of neighbourhood profiles. The aim of the project is to facilitate an energy and resource efficient development in the planning practice of Austrian cities. Furthermore, the project is an important asset for research and planning activities in Europe and can also be applied to other neighbourhoods.
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.
The aim of this project is to optimise the direct usage of PV-electricity produced in buildings. The main question concerning the right dimensioning of the PV generator should be answered in order to achieve a high direct usage rate of produced PV electricity under economic considerations. This analysis will be carried out for various building categories. As result, a calculation method will be developed (incl. report), in order to achieve the optimal, most economic PV system for various building categories and user typologies.
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.
