ARIS - Application of non-linear control engineering and implementation of intelligent sensor systems for the improvements of energy efficiency in the building sector
The major goal of the project was the development of innovative control concepts for controlling and optimizing heating, cooling and ventilation systems (HVAC) as well as building loads. The implementation of advanced, energy efficient non-linear control techniques in building management systems is supported by new sensor technologies that are applied to building and energy systems in order to improve their energy-efficient operation.
The aim of this project was to advance the state of the art in the engineering of double-leaf building facades that facilitate natural ventilation while providing sufficient sound insulation. Realization of natural (window) ventilation is in some instances difficult due to a number of factors. Thereby, noise pollution (especially traffic noise) plays an important role. To address these issues, the project explored innovative solutions in terms of facade constructions for concurrent natural ventilation and noise control.
The objective of this research project is to develop information requirements and process descriptions for the application of BIM models related to building services in facility management and to demonstrate the lifecycle-oriented use of these models in an open BIM environment. For this purpose, software solutions for the use of IFC in the open-source platform SIMULTAN and building management software are developed and evaluated on the basis of four typical use cases.
This project analyzed the integration of decentralized heat sources into domestic heat grids technically, but also economically.
Dissemination of results of the research initiative "Building of tomorrow" for two specific target groups - master builder and installer - implementation in further vocational training concepts
For the future supply of energy services the combination of energy efficiency, energy storage and decentralized use of renewable energy in buildings offers itself. The project identified dynamic potentials of possible active and passive energy yields of construction units with use of renewable energy sources, pointed future solutions to energy-efficient and ecological design of building construction-units and united all results to a signpost: From today's passive house to the energy-plus-house of the future.
COP5+ - Further development of a heat- and cooling system with seasonal heat storage at the example of Central Europe´s biggest geothermal depth drilling field
The aim was to increase the overall energy efficiency of Plus-Energy-Houses by making the heat excess of summer available for use in winter. This was carried out by improvements of the technology seasonal heat storage to an intelligent overall system. The biggest geothermal depth drilling field in Central Europe has been established.
On the basis of our relieable CPC-collector SOLARFOCUS S1 we develop the CPC-lightweight construction collector to get more material efficiency and maximum output of solar hightemperature energy.
The project CiQuSo aimed to develop, evaluate and optimize concepts for solar energy systems to provide energy for buildings and cities. The applicability of the developed methods and concepts were shown as an example at Itzling, a part of Salzburg city.
Evaluation of the quality and efficiency of state-of-the-art installed solar combisystems, potentials for improvements and measures to increase the quality
Connection of innovative strategies and technologies to a holistic, resources-friendly plus energy building (FUTUREbase)
On the basis of a construction project in Giefinggasse 4 in Vienna the combination of new, innovative strategies and technologies to an integrated, resources conserving plus energy building with high signaling and multiplication effect had been tested for feasibility. A regional, energetical bond between the buildings TECHbase, ENERGYbase and the Klima-Windkanal had been developed.
Cooling LEC - Energy-flexible buildings by controlling cooling systems via unidirectional communication in local energy communities
As a result of climate change and the rise in temperature, especially due to the increase in active cooling systems, especially at low-voltage level, new challenges are being posed to the electricity system (in particular to the distribution network). Due to the high electrical input of active cooling units and the high density of plants, which are sometimes operated uncoordinated and at unfavorable times, leads to peak consumption in the system. The project Cooling LEC therefore has as its overall objective the development and demonstration of a central control / intelligence of decentralized active cooling systems by further developing the unidirectional communication of ripple control systems to create energy-flexible buildings in the sense of the new approach of "Local Energy Communities" by creating a "special tariff". Ripple control systems have been established for many decades and are available and proven by all energy suppliers. The upscaling potential is very big.
Using an interdisciplinary approach, the legal, technological and economic aspects of the cross-building exchange of heating and power were analysed separately within a methodological framework which includes different system configurations relevant to the specific situation in Austria.
In the present project an absorption chiller will be adapted to meet the specific requirements necessary to integrate it with the CHP unit. By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.
In the course of DALEC an online concept evaluation tool for architects, building engineers, lighting designers and building owners was developed. Although easy to use, the software accounts for the complex thermal and light processes in buildings and allows a simple evaluation of heating, cooling and electric lighting loads. Not only energy, but also user behavior were considered (e.g. in terms of glare protection) and visual and thermal comfort were evaluated. This novel and innovative, holistic approach makes sustainable and energy efficient building design possible for new buildings as well as refurbishment.
Within the project at hand a production plant with store house and offices had been constructed. It serves as a reality testing field for long-term measurement of components and systems developed in previous projects. It serves for the demonstration of innovative energy systems and components for the interested public and for experts.
Development of affordable building equipment and services for future "Energy Plus houses" (Plus-Hybrid)
"Plus-Hybrid" integrates knowledge and experience from current activities and complement them by adopting a holistic approach, considering the intelligent interconnection of components as well as managing the planned efforts and human resources in time. The goal of this project was to develop affordable building equipment and services for future "Energy Plus houses".
Research on the influence of collector hydraulics, piping and the arrangement of plant components on the stagnation behaviour of thermal solar systems.
Aim of the project Eco.District.Heat is to provide strategic decision-making support that enables Austrian towns and cities to deal with aspects of grid-bound heating (and cooling) systems in accordance with integrated spatial and energy planning from a holistic perspective when elaborating urban energy concepts.
EnerPHit-green concept Modernisation of a historic building with application of an aerogel insulation plaster
This demonstration project shows the comprehensive modernization of a historic building within the constraints of a regional protection zone. By using the Aerogel high-performance insulating plaster, a comprehensive energy-efficient building refurbishment had been realized without changing the outer appearance of the façade.
