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.
GREENsChOOLENERGY - Development and practical implementation of sustainable solutions for urban hotspots in combination with greening / PV / water
Use of the synergetic effects in the construction of photovoltaic, greening and irrigation systems at the location of HTL1 Klagenfurt Lastenstraße, to optimize the yield of experimental photovoltaic elements and at the same time reduce urban heat islands.
The declared aim of the project is the development of the GREeNvaluation toolkit, as a precursor to the implementation of green and liveable cities. The visualization and accounting (cost / benefit) of green infrastructure services makes the benefits more tangible and understandable. The GREeNvaluation toolkit aims to create awareness far beyond the target areas by means of target group-specific communication formats.
Heat Harvest - Harvest of urban solar excess heat from buildings and surfaces to avoid summer overheating in cities
"Harvest" of solar urban excess heat from building surfaces, sidewalks, streets and squares to avoid urban heat islands by lying flat absorber pipes, which are then fed into geothermal probe storage tanks for later use as a source for heating buildings.
Application of the prototype in the operational environment for a period of 20 months. Technical monitoring thoughout the cycle of seasons, user interviews concerning satisfaction, evaluation of the potential use of LooPi material streams as soil conditioner for organic farming. Results serve the development towards market maturity.
MUFUWU Stadtbaum - Development, evaluation of multifunctional urban tree habitat in existing streets. Root zone, retention, microclimate
Applied research and development of a construction concept for road construction that enables the establishment of large-crowned urban trees and is tailored to specific local requirements, such as metrological, geological, and climatic conditions. The results are taken as a basis for a standard construction concept for densely built urban areas.
