An integrated technical energy plus office concept without additional building costs demonstrates the feasibility of such projects instancing a concrete office project with 50.000 m² floor area in Vienna with economical cost consideration.
The aim of the project is 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.
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.
Sol4City - Integrated solar supply concepts for climate-neutral buildings for the "city of the future"
Intelligent technology coupling to achieve high solar coverage of the buildings (multi-storey residential building) heat and electricity demand. At the end of the project, integrated energy supply concepts for multi-storey residential buildings based on high network interaction and flexibility potential, maximum surface efficiency of conversion technologies on site and high economic competitiveness are available for the broad applicability in the "City of the Future".
Goal of this subproject was to select the building with the highest potential within a building-portfolio. Therefore a criteria catalogue was developed, which is generally applicable.
Development of transparent, technical and economic models for medium and high volume residential buildings, with special focus on the non-profit sector. Topics such as generation living, teleworking as well as smart homes are developed in an integrated model, for dense structures as well as pavillons and townhouses. All models follow the three pillars of sustainability.
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.
OttoWagner-ArealPlus - Feasibility study for a certified plus-energy-district-renovation of the listed Otto-Wagner-Area
Development of an innovative concept for the transformation of the Viennese Otto-Wagner-Area into a plus-energy-quartier while meeting requirements of cultural heritage management. The historic architectural jewel covers an area of around 50 hectares, consists of 70 buildings and a gross floor area of around 200,000 m². The solution meets highest energy efficiency standards and comfort requirements.
In a practical way the project showed that with optimised small wind turbines a useful potential of wind power can also be generated at different suitable locations with low wind conditions directly at households and companies.
A Catalogue of Passivhouse Details for Refurbishments for buildings of all building periods from the 1870 to the 1980s. Special consideration to the refurbishment of building parts in contact with the earth. Integration of controlled ventilation services. Construction elements description with drawings, building physical data and ecological life cycle assessment. This project aimed at contributing to "Replicable refurbishment concepts for meeting passive house (or comparable) standard in buildings of all building periods".
Based on the selection of suitable demonstration projects in Subproject 1 an innovative concept for passive and active building envelopes and energy supply of so called "Plus Energy Buildings" (renovation) has been developed.
The "oh456 Plus Energy Office Building" with its adjoining small hydro-electric power plant shall serve as a prototype for testing innovative technologies and also provide the companies residing in the building integral home surroundings comprising common break and leisure facilities. A wide public will have access to the building which will be a location for the most diverse events, exhibitions and lectures on climate protection as well as being a joint promotional platform for sustainable construction.
The aim of this project is to optimise the direct usage of PV-electricity produced in buildings. The main question concerning the right dimensioning of the PV generator should be answered in order to achieve a high direct usage rate of produced PV electricity under economic considerations. This analysis will be carried out for various building categories. As result, a calculation method will be developed (incl. report), in order to achieve the optimal, most economic PV system for various building categories and user typologies.
ArcheNEO is a highly energy efficient office park, that produces more energy than it needs. It features an integrated energy concept that saves energy, uses renewable energies in combination with electric mobility and batteries as electricity storage and manages energy and was planned and built in Kitzbühel Oberndorf. The demonstration object will be multiplied and exported.
Future quarter 2.0 - Replicable, thermally and electrically grid-supportive conception of (positive energy) districts in a dense urban context
Development of a replicable concept for grid-supportive integration of innovative (positive energy) district with high on-site energy supply into the existing network infrastructure (electricity and district heating network).
The objective of the project was to develop online teaching materials on the topics energy-efficient buildings and renewable energy sources in collaboration with technical vocational schools and vocational higher secondary schools.
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.
The multifunctional neighbourhood "+ERS - Plus Energy Network Reininghaus Süd" was realized within the urban planning area of Graz-Reininghaus. The project aims to optimize the energy concept of the single buildings as well as of the building cluster in order to achieve a plus-energy standard within the residential neighbourhood.
Elaboration and programming of a software that reduces effort and time consumption of Passive house and Plusenergy house planning. By developing direct interfaces between CAD-applications and PHplusCAD and interfaces between PHplusCAD and Passivhouse planning tools based on MS Excel the system could be improved and the related working processes alleviated.
The demonstration project "Technology centre aspern IQ" showed that the energy required for space conditioning (heating, cooling, ventilation, lighting, hot water) can be covered from domestic energy production.
