Sensible storages, which are currently used in district heating networks for seasonal storage of excess heat (e.g. from solar thermal or industrial waste heat), exhibit high space demand, investment costs and heat losses. Within this project, concepts for using innovative storage technologies, e.g. thermochemical storages (TCS) having high heat densities and enabling pressure- and lossless storage, were developed and analyzed on a technological, economic and ecological basis. Additionally, the regulatory framework has been evaluated.

Feasibility of a resource cadaster to inventorize, characterize and locate material stocks in subsurface infrastructure networks. The results are used for the economic assessment of secondary resource potentials.
Development and coordination of indicators for energy and ecological evaluations of urban areas based on the Swiss 2000-Watt certification system. The results will be used for the development of a quality assurance system for urban areas similar to the klimaaktiv declaration for buildings and the e5 certification for communities.
Participation in CEN TC 350 (sustainability of construction works) - WG4 Economic Performance Assessment of Buildings
Participation in the CEN TC 350/WG4 to develop a standard to evaluate the integrated effectiveness of buildings during their life cycle. Evaluation and integration of national comments in order to prepare the standard for the final vote.
Based on the results of previous research projects, the project at hand deals with the development of a wooden prefabricated module construction for energy efficient office buildings with up to 20 storeys. This sustainable system ensures cost certainty through the whole life cycle of the building.
Development of basic principles and proposals for highly recyclable constructions. A catalogue with main principles of recyclable designing with a particular focus on material inherent bonding and joint techniques as well as a selection of constructions including ecological benchmarks, calculation of building physics plus costs was created.
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.
The focus of the project is on quality assurance within the commissioning process with the aim to speed up and to improve the operational adjustment of newly constructed or comprehensively renovated buildings. The fragmented know-how which is hardly accessible for the relevant target groups will be consolidated and elaborated in the form of a practice guideline which will be directly applicable in commissioning processes in practice. In this way the project contributes to the development of a common, well-established standard for quality assurance within the commissioning of buildings.
Innovation & Cost efficiency: Building standards for multi family residential buildings at optimal cost (Inno-Cost)
In this project, innovative building standards were examined concerning their economical aspects through the life cycle of a building. By means of life cycle-costs for 40-50 multi family lowest energy and passive house residential buildings on actual data from the day-to-day operation, reliable data and know-how was compiled for the first time, which is to support further market penetration of innovative building standards in the field of multi family residential buildings.
Targeting a high level of decentralised energy supply on basis of renewable energy, the project analysed the possible combinations of solar thermal energy, photovoltaic and heat pumps. The project aimed to maximise the domestic energy supply due to utilisation of the building as short term energy storage. In addition to that, several optimisation measures had been developed. The impact on the energy supply and demand will be economically assessed through life cycle costing. On this basis, the potential load transfer and the use of this kind of systems had been evaluated in combination with smart grids.
Energy efficient, resource conserving and differentiated renovation of historic European building stocks (ReCoRe)
The project goal was the development of an integrated, long term and life cycle oriented approach to sustainable modernisation of historical building stocks. Within this project the partners used common objectives and planning tools and followed a common procedure in order to develop a specific national application which results from a historical, technical, social and cultural understanding of the specific national stock fragments.
Cooperative Living Volkersdorf (KooWo - Volkersdorf) - sufficiency, space and energy efficiency in the quarter
The jointly planned demonstration project "KooWo" in Volkersdorf aims at reaching sufficiency as well as energy and CO2 reductions in a holistic way. System boundaries are shifted in order not to look only at energy consumption in buildings, relating to unit of floor space, but to consider all use of resources and relating it to persons and social communities.
The aim of the project is to provide a "proof of concept" of a control loop and tool set for the management, optimization and evaluation of green and climate-sensitive urban (district) planning- The tool set consist of urban and open space planning instruments as well as climate simulations at different scale levels.
BIMSavesEnergy - BIM-based planning-methods for the assurance of energy-efficiency in the building process
The Building Information Model (BIM) brings about fundamental changes in the planning and construction of buildings, as the common base makes it possible to work closely together across disciplines in construction projects. In this project, BIM-based planning methods are developed, which make the influence of planning decisions on energy efficiency quantifiable and controllable in the management process.
The present project aims to close the gap between specialist consultants and Building Information Modeling (BIM) applications. For that, relevant data for cost estimation, scheduling construction planning and management or sustainable building operation and facility management, shall be added automatically to BIM elements and imported into the respective specialist planning software. This data exchange shall be carried out using IFC interface according to ÖNORM A6241-2 and the properties of the ASI properties server via a central platform, the "6D BIM-Terminal".
"Biotope City" is an overall concept for the implementation of comprehensive urban greening with the aim of using the regenerative mechanisms of nature. With this approach, quality of life is to be comprehensively, sustainably and cost-effectively increased and resilience against extreme weather events in cities will be improved. The project aims to generate realistic components of a "construction manual" for the green city of the future, which are generalizable and transferable.
Development of transferable concepts for energy-plus quarters as substantial preparatory work for the implementation of an energy showcase quarter in Vienna based on six concrete areas. The support for the broad application of the concept shall be a precursor for the realisation of future energy showcase quarters in Vienna and other cities.
SCI_BIM - Scanning and data capturing for Integrated Resources and Energy Assessment using Building Information Modelling
