Energy2POG - Hybrid Energy Cluster Pogusch - Renewable energies and cost-efficient operation

The aim of the project was the design, optimisation and demonstration of a hybrid energy supply system as well as optimised material flows for a restaurant and hotel business in an exposed location. The concept allows the integration of material flows into the heat and energy supply system.

Booklet issued by Building of Tomorrow with about 20 practical passive house thermal bridges free connection details for large-volume residential buildings

In particular, for buildings with very low energy consumption on heating the influence of heat bridges have a special value. Since in passive house construction a largely heat bridge free execution is required, the most frequent and significant heat bridges are collected in a booklet.

BIPV as Architectural Tool

15. June 2018
TU Wien, Getreidemarkt 9, 1060 Wien, AT

Within the international meeting of the IEA PVPS Task 15 "Enabling Framework for the Acceleration of Building integrated Photovoltaics (BIPV)", a workshop on "BIPV as Architectural Tool" is organized providing the opportunity to meet local PV-Architects and BIPV stakeholders.

aspern Vienna´s Urban Lakeside - subproject 5: Monitoring of Energy Consumption in Demonstration Buildings in Seestadt Aspern

Goal of the project is to develop a monitoring tool that allows to predict the expectable (final) quality of the residential buildings based on decisions made during the planning and construction phase. For this purpose, the current certification tool for the determination of "TQB-points" will be equipped with "interim" certifications, which shall allow the land developer to carry out a quality monitoring parallel to the construction phase. The tool will be tested with the data obtained from selected construction projects during the first residential development phase in seestadt aspern.

Spatial models as a basis of decision making for the utilisation of regionally available energy potentials for a CO2 neutral satisfaction of the local heat demand

Analytical GIS-methods to model regionally available renewable energy potentials for the evaluation of measures to achieve a CO2-neutral heating and cooling supply.

Scenario assessment for the economic market potential of relevant energy technologies.

Economic analyses and scenarios for the future relevance of various sustainable energy technologies considering interaction of technologies, learning effects and exogenous scenario parameters. Recommendations for the future orientation of research and technology development.

IEA SHC Task 58/ECES Annex 33: Material and Component Development for Thermal Energy Storage

This Task/Annex addresses second generation materials for PCM and TCM energy storage and includes material development, characterization and testing under application conditions. In addition, the focus was on the interaction between material and storage component and on the expected storage performance of innovative materials.

Transferproject: Professional strawbale building - "Virtual building-site", exhibition and instruction material

Strawbale-workshops are considered as the best way to inseminate this ecological building-technique. The "virtual building site" has some decisive advantages over the common situation: it does not depend on the weather, allows the comparative study of different constructing methods and can, as a permanent installation, be used as an exhibition.

IEA HPT Annex 59: Heat Pumps for Drying Processes

Drying processes are highly energy-intensive and widespread in industry and commerce as well as in households in various forms. In this project, the potential for energy savings in drying processes in various applications will be investigated, which can be tapped through the use of heat pumps and made available to the relevant target groups in the form of guidelines, data, etc.

IEA HPT Annex 64: Safety measures for flammable refrigerants

New bans on chemicals and the revision of the so-called F-Gas Regulation pose new challenges for the heat pump and refrigeration industry. In this project, new knowledge regarding the safe future use of flammable refrigerants in heat pump and refrigeration systems up to 50 kW for room temperature control and hot water preparation is being developed and made available to the relevant target groups.

IEA Bioenergy Task 45: Climate and Sustainability Effects of Bioenergy within the Circular Bioeconomy (Working period 2025 - 2027)

Promoting sustainable bioenergy as part of the circular bioeconomy: Task 45 participation aims to improve understanding of the environmental, social, and economic impacts of bioenergy. The focus includes regional differences and the development of robust impact assessment methods to support decision-making by stakeholders such as communities, businesses, and governments.

User-friendly heating and ventilation systems for low energy and passivehouses

The goal of the research project is the evaluation of different heating and ventilation systems for passive- and low energy multi family and office buildings taking into account indoor climate, possible variation of user behaviour, final and primary energy demand, costs, space demand and fail save installation and operation.

urban pv+geotherm - Innovative concepts for the supply of large volume buildings/ quarters with PV and geothermal energy

The use of renewable energies in inner city locations is mostly linked to higher costs andconsidered as problematic. The aim of this project was to optimize (cost and energy) heating (and where required, cooling) using geothermic and photovoltaic for an urban, densely-built development area. With the project´s findings it will be easier to ecologically and economically plan the use of renewable energies especially in urban areas.
