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.
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.
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.
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.
In course of the monitoring project the effectiveness of the energy-technical system was checked on the basis of running measuring data. The data were evaluated and, if required, the arrangements and settings of the control system were adapted. Main result is that the energy balance could have been improved explicitly whilst the monitoring process.
All pilot projects of "Building of Tomorrow Plus" had to be evaluated in a common monitoring project on energy efficiency, user's acceptance, and the integrated building performance. monitorPlus documented and assessed the results of this evaluation.
This study uses several data sources to analyze the effects of the research programe "Haus der Zukunft" ("Building of Tomorrow") on the Austrian housebuilding industry and the built environment.
This project addressed the development of construction details for the implementation of vacuum glazing panels in new windows. In this project such constructions (form of frame, thermal bridges, structural aspects, mounting of glass) were explored via empirical experiments and via simulation. As an outcome, a mock-up was constructed, and the findings were documented in a comprehensive document.
Based on the results of the national-funded exploratory projects called “Smart Exergy Leoben”, and “Energy Sponge Bruck”, the present implementation project aims at analysing how local, renewable resources support the supply of electric mobility in Leoben in the long term and to integrate it into the municipal distribution grid in a good economic sense.
Multi-Activ-Facade is a pre-manufactured, multifunctional panellised façade, which incorporates ventilation with heat recovery, passive house windows and photovoltaic for smart self-supply within retrofitting measures. The specific challenge is the application within social housing.
Sustainable mixed-use utilization of urban commercial and industrial areas with a specific focus on energy-related aspects.
In the frame of the project a classification system for Smart City Technologies had beed developed, the relevance of a wide range of technologies in terms of their potential contribution to the development of sustainable and more resilient cities with a high quality of life had beed evaluated and a comprehensive classification of the technical maturity of relevant technologies, technical (sub-)systems and technology-related services had been given.
The main goal was to raise awareness for energetic renovations of settlement houses due to the handbook "Neue Standards für alte Häuser" in Slovakia and the Czech Republic. In doing so, the refurbishment potential has been identified in the target countries, experiences exchanged and information transferred. Contacts to the relevant target groups have been established.
In the NETSE project the basics for the implementation of energy communities are developed. This includes the relevant technical equipment and interfaces, the development of a platform for the operation of an energy community as well as tools for the optimization of the technical setup and the operation of energy communities.
The use of sustainable building materials is a key issue for sustainable development of the building sector. Emission free indoor air, minimized embodied energy of construction materials and health risk for construction workers are three main aspects. Between five hospital operators in Austria, Germany and Switzerland a practical exchange of experience focused on material ecology will be initiated and moderated.
