Highly energy efficient presence detectors, control systems for sun shades etc. are de facto not available on the market. Regarding plus-energy office buildings, the minimisation of the power consumption of these components is a central criterion to achieve the "plus" part in terms of the energy of the building. A highly energy efficient presence detector was successfully sketched in this project, which undercuts the intended standby consumption of 0,05 W.
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.
LTS Flywheel - Long Term Storage-Flywheel: New approaches for increasing the economically usable storage time and safety
Development of the fundamentals for a Long Term Storage (LTS)-flywheel for decentralized storage of electrical energy (e.g. from wind or PV power plants), with a significant increase in storage time (goal: 12 hours) and safety, featuring low system costs. Therefore, the LTS-Flywheel is an essential contribution to the building of the future.
The research project investigates how digital technologies can support us in determining the existing and future material resources in construction qualitatively (building materials and their recycling) and quantitatively (quantities of building materials).
Maize cobs accrue as an agricultural by-product can be used for a core material of light weight panels with good material properties and insulation characteristics. The aim was to work out a concept for the production and optimisation of material properties.
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.
ARAFIT develops a concept for the regional management of the loads of public water treatment plants in a partnership of planners, operators and major water consumers following the idea of sustainable least cost planning resulting in efficient, flexible and future oriented regional infrastructure.
Compilation of the manual to realise initiatives for energy regions of tomorrow; integrating the experiences generated in the winner projects, outcomes of representative energy-projects and the know-how of scientific works; distribution by multiplicators, realization of distribution activities
The intention of this project was to visualize the current activities of the IEA Energy Technology Network and to identify possible gaps and overlaps. The mapping includes 185 ongoing tasks and annexes (Status September 2017).
Concept for launching of a new business unit or an independent ROI-Contracting Consulting with effects on sustainable development.
Stationary battery storage devices for the maximisation of the private consumption in PV-systems, large heat storage for local and district heating systems, thermal activation of buildings and the area of innovative storage systems have been chosen for the first market survey within this project. The historical market diffusion of these technologies is surveyed empirically and documented up to 2020.
Mechanical processing of the non-reusable part of collected end-of-life apparels (e.g. cutting, sifting, etc.); development of marketable application for the obtained short fibers in the field of construction materials (e.g. bitumen modification)
Analysis and implementation of alternative ventilation systems for windows, focusing on thermal renovation of old buildings. The investigated ventilation systems were presented to an expert group. The aim was to discuss ventilation technologies with the help of different aspects and to develop a SWOT analysis.
MehrWertStrom 2030 - PV-Community system - Exploring a participatory pilot project with regional added value for structurally weak regions
The "MehrWertStrom 2030" project analysed the legal, technical, organizational and economic feasibility of PV community joint venture facilities on multi-party buildings including the added value for structurally weak regions and developed innovative solutions related to organization, financing and realization.
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.
Methodical optimisation of biogas plants based on strategic learning from realised plants and projects.
Methodical optimisation of biogas plants based on the preparation and presentation of affirmative experiences and mistakes from the realisation of plants in the past. Combination of experiences from different industrial sectors (designer of plants, assemblers, consulters and operators)
Development of a mobile and modular thermally-driven-cooling-system for cooling powers ranging from 17 to 210 kW. The driving heat is provided by solar collectors and a biomass boiler. For research purposes a cooling systems (70 kW) will be installed in Gleisdorf where the company EnergyCabin is located.
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.
Concerning to an accurate and adaptable construction of 2 to 4 storey solid timber houses with the characteristics of a passive house, a digital construction and dimension system will be developed. The system which contains standardised modular ecological detailed solutions enables an exact dimensioning and installation of passive houses by small carpentering companies.
