THERM-opti-BALCONY-P2 - Thermal Optimized Renovation of Balconies Phase 2: In-Situ-Pilot-Station

Pre-cast cantilever balconies represent a particular problem in the case of thermal rehabilitation of buildings. With the THERM-opti-BALKON-System a solution is currently being investigated under laboratory conditions. Phase 2 aims to create an in-situ-pilot-station. The most important object of study is the long-term behavior of the THERM-opti-BALKON-System.

Evaluation of temperature differentiation on a room-by-room basis in passive house apartments

In the passive house Utendorfgasse a room–by-room temperature control was installed in 11 apartments. The experiences were evaluated from a technological and from a sociological point of view.

"gugler! build & print triple zero" - subproject 3: recyclable constructing

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.

ZSG - Sustainable Concepts in urban redevelopment and building refurbishment

Project on research and implementation for ecological and energy efficient concepts, urban redevelopment and building refurbishment. Performance of a routing project on a former ter-ritory of the Austrian armed forces in Steyr.

Gründerzeit with future - sub project 2: Foundations and feasibility studies

Documentation of available knowledge on the renovation of historical buildings ("Gründerzeitgebäude") as an input for the preparation of 5 demonstration projects as well as the development of an accompanying monitoring system within the scope of the project "Gründerzeit with future".

Certified passive attic conversion of a typical building from the period around 1900

Conversion of an attic of a typical building from the period about 1900 to a passive attic with photovoltaic system and renovation of the existing building equipment. The aim is to keep the additional construction costs under 10 %, to avoid overheating in summer and to make possible a reproduction for the large amount of buildings from the same period.

ThermSat - pilot training program "Thermal renovation engineer in construction industry"

The goal was to design, offer, evaluate and refine a practical training, adapted to the current development. Aim of the courses is to have well-trained engineers and technicians with practical and theoretical knowledge in the field of thermal renovation of buildings.

GAINING BUILDING LAND without expansion - development of single-family housing settlements

Identifying and utilising potentials for higher densities and re-structuring in single-family housing areas requiring renewal

School vent cool - Ventilation, cooling and strategies for high performance school renovations

Based on a building typology, strategies for prefabrication for high-quality thermic-energetic renovation of school buildings were developed. New solutions for ventilation systems to achieve good air quality and shading systems were analysed and tested. The "School vent cool" method for renovation of schools has been developed.

COOLSAN - refrigeration concepts for office and administrative buildings retrofit

Technologies to enhance comfort and minimise energy requirements for air conditioning in existing office and administrative buildings. Possibilities to reduce the cooling loads and strategies for the use of passive cooling systems.

Existing building reconstruction and implementation of passive house components

Implementation of passive house components, systems and techniques into the practice of existing building reconstruction, in order to reduce the energy consumption as much as possible and to increase the living quality substantially. Craftspeople and planners, who are specialized in building renovation, should gain access to passive house know-how.

"Communal living for elderly - ecological, social and economical aspects" - eco-com.60+

The research project examined different forms of communal living of elderly people and contributes to the development of new, common forms of living for the elderly. Questions concerning demographic change and economic as well as ecologic challenges of our time had been dealt with.

BIGMODERN - Subproject 5: Feasibility studies about innovative technical solutions

The application of innovative technologies means additional planning and coordination effort which usually cannot be incorporated into the conventional planning processes of the BIG. To overcome these barriers for the application of innovative technologies, the sub project at hand aims at preparing information, feasibility studies, planning records, experiences and practical examples in a way, that they can be implemented directly into the planning process.

WOP - Restoration of residential buildings in passive house quality, Linz, Austria

Pilot scheme for the restoration of the multi-storey residential buildings to a low energy building while people keep living in their flats with energy efficient, ecological and economical criteria.

"gugler! build & print triple zero" - subproject 5: Ecoeffective building

On the basis of the commercial building gugler with 2140 m² useable floor area existing and 3260 m² useable floor area to be built a concept for a 100% recyclable ecoeffective building will be developed.

Gründerzeit with future - subproject 5: Documentation and monitoring

The main aim is the documentation and monitoring of the demonstration projects within the scope of the project "Historical buildings of tomorrow" with regard to the technical implementation, investment and operation costs and to the energetic performance. All demonstration projects will be accompanied by an evaluation process regarding occupants' satisfaction and the refurbishment process. Beyond that, legal constraints for innovative refurbishment of historical buildings will be documented and proposals for adaptations of the rental law and refurbishment subsidy schemes will be developed.
