Operational and maintenance costs in passive houses and low energy houses

How much energy does a passive house actually save? Does a passive house pay-off by itself? What are the costs for maintancence? For the first time an approximation for the running costs of a passive house were systematically documented and compared.

ÖkoInform - Platform for Exchange of Information in Green Building

A platform for the exchange of information to promote the better integration of ecological materials and renewable resources in the research programme "Building of Tomorrow"

The Passive House Catalogue of Building details for renovations

"Building of Tomorrow" funded research reports dealing with building renovation will be analysed for solutions of construction details. This information will be supplemented with structural-physical descriptions, ecological ratings and technical discussions. All the information will be collected and systematically presented in a catalogue of building details for renovation.

Development of a clay - buildingboard with a surface ready to paint

Development of a building board consisting of a wood fibre board, coated with clay-plaster reinforced by natural plant-fibres (BioFaserLehm) for reinforcing planking of timber-constructions and also for statical not stressed inner wall surfaces.

1000 passive houses in Austria - 2nd documentation period 2004 - 2005

2nd documentation period of the joint project of IG Passivhaus Österreich under the programme line "Building of tomorrow", an initiative of the Federal Ministry of Transport, Innovation and Technology (BMVIT) to set up a detailed network documentation on a representative cross-section of all passive houses in Austria.

New High thermal insulated lightweight timber-frame constructions

Development for the application in the passive house standard (e.g. low-energy houses).

Passive house Kindergarten with an integrated therapeutical group

Applied passive house techniques with locally available materials for a public building using limited funds.

CityCalc - Calculation Tool for Energy-Efficiency in Urban Planning

To assess the energy performance of urban planning projects in early design stages with low input and evaluation effort within the project CityCalc, an easily applicable planning and evaluation tool has been developed.

To Renovate with Common Sense - Building of Tomorrow - A Film Project

A professional documentary film and detailed construction-documentation upon the subject of innovative thermal renovation of matured apartment houses and tenement blocks in Austria.

LEKOECOS - combined economic-ecological life cycle assessment model

The consumption of ecological and economic resources over the whole life cycle is supposed to be anticipated and optimised in the design process of buildings and refurbishments. A combined life cycle assessment model together with an economic-ecological base element catalogue considering the klima:aktiv criteria was developed based on the structure of the life cycle cost model LEKOS and the ecological valuation tool Ecosoft.

Applying passive technologies in social housing, 1140 Vienna; Utendorfgasse 7

Multi-storey social passive house construction with 39 units in Vienna, 14 Utendorfgasse under adherence to the international passive house standard and simultaneous extremely low construction costs.

PESI - Paradigm shift in urban energy systems through synergies with industry

Analysis of different options for the use of industrial surplus energies of various shapes (waste heat, waste water, waste) and renewable energy sources in the industrial sector (e.g. solar panels on roof surfaces) in adjacent urban areas, which act as an "energy sponge". Based on real consumption and availability data, a simulation model was created and opportunities for synergies were documented.

PEAR – Test facility for energy efficient automation and control of buildings

The energy demand calculated in the design phase often differs from measured values in the actual building operation. This projects reviews building automation and operation by presenting a solution how to assess energy efficiency of control strategies in the fields of air conditioning systems, concrete core activation and free cooling. The results are implemented in the demonstration building "Post am Rochus".

SpeedReg - Prompt quality assurance of the commissioning process of buildings

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.

Urban consolidation Lehen - Subproject 2: Development - intelligent E-Monitoring

In the oppositional subproject 2 technical and organisational requirements for the transformation of the innovative Smart Metering-concept will be developed. Through the connection of the application of Smart Metering with an active integration of the inhabitants over mutual communication the concept, which is planned for the key project Urban Consolidation Lehen stands out of other comparable antedated activities.

SchulRen+ Innovative plus-energy refurbishment concepts for school buildings

In a technical feasibility study and based on a real example, the project analysed innovative plus-energy refurbishment concepts for school buildings. The goal was to develop refurbishment concepts with a high replication potential which combine future-oriented energy concepts with feasible technical and architectural solutions.

Thermo-Active Building Systems - Development of a Calculation kernel (TBA-CALC )

This project result will provide Austria with a uniform software environment for the simulation of thermo-active building systems in the form of a validated tool.

Comfort and cost optimised air guiding concept for energy efficient housing

Ventilation systems for dwellings can be more efficient in terms of cost and energy, if the air guiding concept with cascade principle (overflow of air from sleeping rooms into living room). In this project, the planning principles had been developed and published in practice guidelines.

Ecological restoration of a listed building with passive house technologies

Ecological exemplary reconstruction of the "Haidenhof"-building, Bad Ischl, Upper Austria. Building refurbishment with respect to monumental protection and newest passive house technologies. Reorganisation of the former residential building to an academy of arts and culture.

Strat-CON - Strategic Actions for Realising the Vision of ICT in Construction

Refinement and validation of the implementation proposals in order to achieve the realisation of the ROADCON vision and roadmap for ICT in construction by means of stakeholder-workshops, structured interviews and questionnaires.
