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.
Energy-Sponge-Bruck (Energieschwamm Bruck an der Mur)
The aim of the exploration-study for the urban region Bruck/Oberaich "Energieschwamm Bruck" or "Energy-Sponge-Bruck" was to establish clear and stringent basics for a flexible development of the future energy system. Therefore an energy development concept as well as a cadaster for short-term implementation measures had been applied. The structured, Bruck-based approach acts as framework for a general energy-conception-method, valid for small and medium urban regions with 10,000 to 20,000 inhabitants.
Intensified Density - a small scale densification strategy for the suburbs by using modular construction
The project investigated whether a small scale densification strategy for the suburbs / intermediary cities, using modular construction, and existing infrastructure on empty plots of land, can offer a competing alternative to not only the sprawl of single family dwellings but also to large projects.
PVOPTI-Ray, Optimization of reflecting materials and photovoltaics in urban environment with respect to energy balance and bioclimate.
Within the scope of the project PVOPTI_Ray the influence of reflection and energy balance on the performance of building integrated photovoltaics (PV) in complex urban environment have been investigated. Equally the influence of PV modules and of the energy conversion of solar energy at the PV module surface has an impact on micro climate and therefore also on pedestrians who are exposed to the radiation fluxes. This was also investigated.

Building Information Modelling supported compilation of a Material Building Pass; as a qualitative and quantitative documentation of the material composition of, and the material distribution within, a building structure. This project is a central milestone towards standardized, BIM-generated building material passes.
StadtKlimaVISION - Preparing an urban innovation laboratory for climate-neutral urban planning: It's starting in Linz!
In StadtKlimaVISION, an innovation laboratory for climate-neutral urban planning in the city of Linz has been designed with the aim of aligning urban planning instruments more closely with climate change adaptation and climate protection and involving stakeholders from business, science and civil society.
Multi-WP – High-efficiency multivalent heat pump concepts for the thermal use of external air with geothermal storage
Optimization of multi-WP systems consisting of air-source heat pumps and geothermal storage with regard to increasing flexibility and efficiency from 30 kW for individual buildings as well as neighbourhood solutions and addressing aspects such as PV utilization optimization, mode of operation, utilization conflicts and noise pollution from air-source heat pumps. The project will establish the use of the heat source external air in combination with seasonal storage as a particularly efficient alternative for heating, cooling and hot water supply.
Piezo-Klett: Development of piezoelectric hook-and-loop application for the energy supply of active sensor technology in the building industry
The present project considered 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.
Counterintuitive Building Types - Innovation Potentials for Sustainable Transformation of Commercial and Retail Locations
Selected commercial retail and properties provide existing resources for this project’s case studies that will convert and further develop them towards more positive energy, use, and life cycle balances. The currently underperforming properties will be transformed into more active and attractive places of higher experiential density and environmental relevance through multiplication of space and uses in the interior and exterior areas, demonstrating opportunities for more sustainable development of these understudied building typologies.
UrbanEnergyCells - Requirements for the implementation of energy cells in future energy system designs
The transformation of the currently hierarchical electricity system into a renewable, decentralized electricity system poses major challenges for the actors in the energy industry and society. Most of the installed decentralized renewable energy sources are installed in rural areas, due to easier legal implementation and shorter decision-making pathways. However, the energy density in urban areas is significantly higher, resulting in a transport of electrical energy to the consumption centers.
Low Tech - High Effect! An overview of sustainable low-tech buildings: realized best practice examples, innovative approaches, principles and systematic solutions
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.
CityStore - Sondierung des wesentlichen F&E-Bedarfs zur Optimierung von städtischen Energiespeichern in integrierten Energiesystemen
CityStore pursues a first-of-its-kind, innovative approach on spatial location of storage needs and potentials. This includes the evaluation of concrete challenges and prerequisites as well as the identification of useful storage technologies and capacities. Model calculations for the model cities Graz and Weiz will be carried out. If, and to which extent, the results can be generalized will be investigated in the Follower Region South Burgenland. The results should enable optimized planning and realization of urban energy storage facilities – thereby enabling targeted investments in energy infrastructure to achieve (local) climate and energy targets.
Reallabor Weizplus - Reallabor climate-neutral region Weizplus
Clarification of relevant questions for the potential establishment of a real lab in the region of Weizplus, which aims at a 100% supply of the region with renewable energies by 2030. The content-related technological focus of the activities of the future real lab is on all energy-relevant sectors (heating, electricity, cooling) applied to the focal points of energy efficiency and replacement of fossil energy in buildings, in trade and industry as well as mobility.

Strategien zur Marktaufbereitung für das Passivhaus im Osten Österreichs
Ist ökologisches Bauen in der Masse kostengünstig umsetzbar?
Beim Passivwohnbau Utendorfgasse wurden extrem günstige Baukosten erreicht. Würden sich die Baukosten im Falle einer Ausführung mit ökologischen Materialien verändern? Anhand des Ökologischen Bauteilkatalogs und eigener Kostenkennwerten ähnlich großer Projekte werden die Mehr/Minderkosten ermittelt.

Aufbauend auf einer Literatur- und Technologierecherche wurde exemplarisch an Hand eines modernen Bürogebäudes aufgezeigt, welche Konzepte für eine Versorgung mit Gleichstrom schon existieren bzw. welche sinnvoll erscheinen, wie hoch die Effizienzpotenziale sein könnten, welche Einrichtungen dafür erforderlich sind und welche Vor- und Nachteile erwartet werden können. Neben einer ersten Einschätzung zu den Möglichkeiten und zum Potenzial der Anwendung von DC-Versorgungs-, Verteilungs- und Anwendungstechnologien wurden Zukunfts- und Forschungsfragen definiert.
