There is - worldwide and in Austria - a significantly increasing demand for building cooling. This is driven by a combination of increasing prosperity, urbanization, demographic developments and, not least, climate change. At the same time, and this is the background of the call for tender for the R&D service in question, the current state of knowledge is not yet sufficient to derive concrete conclusions for politics and administration or to initiate technological innovations. According to the call for proposals, the project objective is therefore, firstly, to present and quantify the future cooling demand of buildings and quarters in Austria, secondly, to support decision-makers in the development of climate protection measures and climate change adaptation strategies and, thirdly, to provide energy suppliers and administrations with the necessary information. thirdly, to provide energy suppliers as well as technology and component manufacturers with an estimate of the future cooling demand. These goals will be achieved by firstly a systematic analysis of the formation factors of the increasing cooling demand, secondly a scenario analysis of the cooling demand against the background of different climate scenarios, building structures and comfort demand levels, thirdly, a structured techno-economic technology analysis and fourth, an exemplary application of the findings to five exemplary neighborhoods. The results will be used to draw meaningful, target-group-specific conclusions and recommendations for action. In particular, the cooling demand scenarios will be translated into cooling demand maps.

This project addresses alternative strategies for texturizing plant proteins for the production of sustainable meat alternatives. Currently, vegetable proteins are produced by extrusion technology using high temperature and pressure. This is an energy-intensive and expensive process, which also negatively affects the nutritional properties of food ingredients (e.g., vitamin denaturation and oxidation of oils). This project aims to explore an alternative method for protein texturization based on ultrasonic denaturation of proteins. This will provide a more cost-effective and energy-efficient method for the production of meat alternatives, which will also have a positive effect on the sensory properties of the final products.

For CO2-free urban logistics, construction site logistics is an as yet unsolved problem. Freight transport with high tonnages contributes to high pollution of both CO2 and nitrogen oxides (NO and NO2). Across Europe, the limit values for nitrogen oxides are regularly exceeded, especially in cities.[1] in a large city like Vienna, construction site traffic accounts for about two thirds of freight traffic in tonnes.[2] The construction of one flat causes about 60 lorry journeys. A total of between 2,500 and 3,000 kilometres are covered in the process. The average annual residential construction output in Vienna of 5,000 dwellings thus generates about 15 million lorry kilometres.[3] Typically, older trucks tend to be used in construction site traffic. Due to the high proportion of heavy goods vehicles and the fact that some of these vehicles are already older, construction site journeys account for around 10% of total traffic emissions.[4]
