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.
SocialLowCostFlex - Collaborative flexible low-cost energy supply concepts for social housing
This project aimed for feasible low-cost solutions, which allow residents of multi-party houses, with special focus on social housing to profit and participate in the energy transition process and associated trends (e.g. community generation units, exploitation of flexibility). The results of the project are low-cost concepts and business models of community generation units and utilization concepts, tested for their feasibility in a social housing complex. These concepts are based on special requirements of different lifestyles in low-income households and take the framework of social housing such as tenant fluctuation into account.
FiTNeS - Facade integrated modular Split-heat pump for new buildings and refurbishment
The goal of FitNeS was the development of modular split heat pumps with compact and silent façade-integrated outdoor units for heating and domestic hot water preparation (and optionally cooling in combination with PV). The outstanding features of the concept are a modular design with a high degree of prefabrication and representing a visually and architectonically attractive, economic and sustainable solution for both new constructions and renovations. One of the main development goals is the minimization of sound emissions by means of optimized flow control.
fit4power2heat
The integration of heat pumps can increase the cost effectiveness of existing heating networks and counter the high costs for the expansion of power grids at the same time. Aim of the project is to develop innovative business models for small and medium municipal heating networks with focus on synergies between heat and power market. Main focus is a heat pump pooling for several heat grids.
BIMBestand - BIM-based management of existing buildings
The objective of this research project was 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 were developed and evaluated on the basis of four typical use cases.
ecoRegeneration: Development of a "Merit-Order" in order to assess regeneration heat for geothermal probes within urban residential neighbourhoods
In urban residential areas there are not enough active-cooled usages, to use the waste heat of the cooling process as required regeneration heat for geothermal probes; free cooling of the apartments is not sufficient. The project is developing various options (waste heat from commercial uses in the ground floor zones of residential buildings, by using waste heat of data centres, additional installation of heat generation systems for regeneration) within the urban settlement area, business models and is calculating life-cycle-costs of all solutions. The result should be a kind of "merit order" for regeneration heat.
Using buildings as energy storage - Monitoring project: Detached house H and detached house F Energy source wind power – Energy source solar power
Monitoring and comparison of performance of thermally activated building components in two similarly built, inhabited detached houses with different energy sources (wind and solar power). The functionality of energy supply through wind power or solar energy will be investigated as well as the verification of the practicability of self-regulating system control due to building temperature behaviour. The results provide an insight into the calculation assumptions, system control and feasibility of the smart grid technology.
Eco.District.Heat - Potentials and restrictions of grid-bound heating systems of urban areas
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.
Exploration of window systems with innovative glass - especially vacuum insulating glass - for building renovation
Exploration of the use of the first fabricable highly insulating vacuum glazing (VG) for highly efficient window systems specifically for the renovation of existing buildings via Verification of the availability and performance of Vacuum Glazing VG worldwide, concepts for structural optimization and thermal simulations of integrated systems, investigation of typical applications and market potential studies and identification of achievable energy savings for single buildings and settlements.
Urban district heating extended – Development of flexible and decarbonized urban district heating systems
Development of innovative urban district heating systems by integration of long-term thermal storage, large scale heat pumps, large scale solar thermal installations, waste heat recovery and analysis and evaluation by simulation. The results of this project will provide templates for technology selection, system design and merit order for new urban district heating areas.
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.
Model Predictive Control von aktiven Bauteilen und Messungen in zwei Test-BOXen (MPC-BOXES)
Es wurde eine robuste, standardisierbare, prädiktive Regelung mit Wettervorhersagedaten für thermische Bauteilaktivierung entworfen, untersucht und ökonomisch bewertet sowie mit herkömmlichen Regelungen, insbesondere für Kühlzwecke, verglichen. Simulationen und Messungen an zwei für diesen Zweck geplanten und aufgebauten Test-Boxen dienten zur Analyse von Energieeffizienz und Komfort.
