LifeCycle Tower - Energy efficient prefabricated multi-storey timber houses
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.
SPRINKLE - Smart city governance processes in small and medium-sized cities
The project aimed at comprehensively analyzing existing approaches for the coordination and regulation of Smart City development in small and medium-sized cities. In the context of case studies, this study combines the analysis of relevant legal-institutional frameworks as well as of governance processes for selected, energy-related fields of urban activity.
aspern Vienna´s Urban Lakeside - subproject 6a: Energy Consumption Monitoring
This subproject of the flagship project "aspern plus" derived the basis for a centralised monitoring of the energy consumption in Seestadt aspern.
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.
scaleFLEX - Scalable method for optimizing the energy flexibility of districts
Development of a decentrally organized automation method for improving the demand-side flexibility options of buildings and districts. The utilized data-driven algorithm promise high scalability and therefore low installation and operating costs. The developed method will be validated using different building types (high-tech office buildings, low-tech office buildings, residential buildings).
MuT - Monitoring of urban Technologies: Classification, Specification, Evaluation
In the frame of the project a classification system for Smart City Technologies had beed developed, the relevance of a wide range of technologies in terms of their potential contribution to the development of sustainable and more resilient cities with a high quality of life had beed evaluated and a comprehensive classification of the technical maturity of relevant technologies, technical (sub-)systems and technology-related services had been given.
Renovation of the "Gründerzeit" building Eberlgasse in passive house standard
Based on the latest available technical capabilities, the renovation of Eberlgasse 3 will show that passive house standard is achievable even in a typical 19th century building.
CiQuSo - City Quarters with optimised solar hybrid heating and cooling systems
The project CiQuSo aimed to develop, evaluate and optimize concepts for solar energy systems to provide energy for buildings and cities. The applicability of the developed methods and concepts were shown as an example at Itzling, a part of Salzburg city.
Development of thermal solar systems with unproblematic stagnation behaviour
Research on the influence of collector hydraulics, piping and the arrangement of plant components on the stagnation behaviour of thermal solar systems.
smartEXT - extended application boundaries for proven passive house technology
The present study aims to explore the application options for compact units (ventilation devices including micro heat pumps, developed for passive houses) in low energy buildings. Compact ventilation units for heat recovery, heating and domestic hot water shall bear the basic heating load, whereas peak loads shall be covered by newly-developed auxiliary heating equipment combined with intelligent control algorithms. This allows increased energy efficiency as well as cost effectiveness together with higher living quality and lower ecological load.
E_PROFIL - neighborhood profiles for optimized energy transformation processes
E_PROFIL is a set of methods (an IT-supported toolkit) for the elaboration of neighbourhood profiles. The aim of the project is to facilitate an energy and resource efficient development in the planning practice of Austrian cities. Furthermore, the project is an important asset for research and planning activities in Europe and can also be applied to other neighbourhoods.
ECR Energy City Graz - subproject 2: Framework-Plan Energy City Graz-Reininghaus
Main project-issue is the scientific work and the demonstration of the vision of the energy self-sufficient, CO2-neutral city-district Graz-Reininghaus. The Framework-Plan Energy City Graz-Reininghaus shall stimulate an awareness-raising process towards energy-efficient and sustainable city-development.
Bi-directional integration of buildings with heat sources in thermal networks
This project analyzed the integration of decentralized heat sources into domestic heat grids technically, but also economically.
Mechanical ventilation system for windows for the renovation of old buildings
Analysis and implementation of alternative ventilation systems for windows, focusing on thermal renovation of old buildings. The investigated ventilation systems were presented to an expert group. The aim was to discuss ventilation technologies with the help of different aspects and to develop a SWOT analysis.
BIGMODERN - Subproject 10: Evaluation, Documentation and Ensuring Transferability
The subproject 10 is part of the flagship project BIGMODERN. It is based on the results of subproject SP 7 in which a monitoring concept has been developed. This concept is now implemented through monitoring of different aspects occurring during the first two years of operation of both BIGMODERN demonstration buildings.
aspern Vienna´s Urban Lakeside subproject 2: Inter-building energy distribution
Development of comprehensive concepts for local distribution systems for thermal and electric energy within a residential area including the consideration of the interaction with construction and city planning. Derivation of measures for demonstration buildings and the infrastructure of the residential area. Integration of computing models to a prototype simulating energy distribution in the residential area.
Update of content and usability for the Manual for Energy Consultants (HfE-New)
The Manual for Energy Consultants had been adapted to present and future needs in energy consulting. The updated manual will preserve the basic concept (buildings with at least close to domestic energy use patterns, up to 1000 m² heated floor area, concentration on refurbishment) and the existing structure: Checklists, data sheets and explanations.
HEDWIG - Collection of measurement data to assess the impact of green buildings
HEDWIG aims for the assessment of effects from green roofs and facades on buildings by using monitoring data referring to microclimate and building physics. The objective is to define validated vegetation parameters and performance indicators on indoor and outdoor level and on microclimatic relevant street space level. Standardised indicators, evaluation and analysis procedures will be elaborated.
BIGMODERN - Subproject 2: Demonstration project of an official building in Bruck
In the frame of this subproject being part of the flagship project BIGMODERN, a decision matrix as well as a handbook for planning, including feasibility analysis and a collection of information, serving as decision guidance for planning and implementation of sustainable building refurbishment, is being developed. In this way, the risk for planners and builders of the usage of new sustainable technologies shall be minimised.
Reduction of maintenance costs of ventilation systems in plus energy buildings
Maintenance costs for central air ventilation systems are approximately 0,42 Euro/m².a excluding VAT, for decentralized systems 1,16 Euro/m².a excluding VAT. 50% savings in operating costs of apartment passive houses opposed to apartment low-energy buildings [SCH11] can be achieved with maintenance costs of around 0,42 Euro/m².a.
