Model Predictive Control of Thermally Active Building Systems and Monitoring of two Test-Boxes
A robust, predictive controller which utilises weather forecast data to control thermally active building systems had been designed, researched and assessed in terms of energy efficiency and comfort compared to standard controllers, especially for cooling purposes. Simulations and real measurements using two "Test-Boxes" with thermally active building systems which are constructed and built for this purpose were used to analyse energy efficiency and comfort. Low complexity and transparency of methods and solutions should allow for transferability of all results to guarantee maximum usability for similar applications.
Monitoring of multi-family houses “Tonpfeifengasse”
Evaluation of activated building parts as heat storage for renewable energy shown on the example of the multi-family houses "Tonpfeifengasse".
Morphology of a City - The Austrian Built Environment
This study uses several data sources to analyze the effects of the research programe "Haus der Zukunft" ("Building of Tomorrow") on the Austrian housebuilding industry and the built environment.
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.
Multi-WP – High-efficiency multivalent heat pump concepts for the thermal use of external air with geothermal storage
Optimization of multi-WP systems consisting of air-source heat pumps and geothermal storage with regard to increasing flexibility and efficiency from 30 kW for individual buildings as well as neighbourhood solutions and addressing aspects such as PV utilization optimization, mode of operation, utilization conflicts and noise pollution from air-source heat pumps. The project will establish the use of the heat source external air in combination with seasonal storage as a particularly efficient alternative for heating, cooling and hot water supply.
OEKOPLUS-KOMPLEX - Analysis of the technical, economical and ecological preconditions for the establishment and utilisation of plus-energy-buildings and building assemblies
The evolution of the low energy house and the passive house standards to the plus energy standard results in a clear reduction of green house gas emissions as well as the primary energy input. The goal of the project was the determination of the technical, ecological and economic basic conditions for the construction and the use of "plus-energy-buildings" in order to finally realize them.
OPEN HEAT GRID - Open Heat Grids in urban hybrid systems
The primary research topic of OPEN HEAT GRID was to investigate the possibilities of enforcing the feed-in of industrial waste heat into existing district heating networks. The project results show that excess heat is not for free: despite minimal variable costs, the investment costs need to satisfy usual payback periods. The analysis shows that there is no need for a regulation in the sense of a feed-in obligation or market liberalization. However, from an economic point of view, information asymmetries exist, which may lead to irrational decisions.
OWA+Quartier - Sustainable refurbishment and energy supply for the historic Otto-Wagner-Areal towards a plus-energy district
Development of thermal and electrical energy supply for the Otto-Wagner-Areal as well as model solutions for construction and building services in order to initiate the redevelopment of the area in the direction of a plus-energy district.
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.
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.
P2H-Pot - Potentials, economic feasibility and system solutions for Power-to-Heat
P2H-Pot has identified economically feasible potentials for Power-to-Heat (P2H) in urban regions. The suitability of different technical system configurations were investigated using thermodynamic simulation and considering experiences from Scandinavian cases. The assessment of short, medium and long term relevance and economic feasibility of P2H were accomplished by simulating model-based scenarios up to 2050 of the Austrian and German electricity and heat market. In cooperation with a district heating company three case studies have been carried out.
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".
PEQBacker: Integrated District Planning - Enabler on the way to a Plus-Energy District
Development of guidelines for the implementation of Plus-Energy District coordination units based on research of success factors, exploration of mission elements of existing structures and consultation of a broad stakeholder group with the goal of increasing the transformation of existing and emerging neighbourhoods toward Plus-Energy Districts.
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.
PH Office - Criterions for energy-efficient office buildings
The passive house standard and energy-efficient building technologies are getting increasingly important for office buildings, too. However, standardisation is not completed on the same level as known from the residential building sector. The project at hand brings in definitions and makes a suggestion on a standardised calculation method for office buildings in passive house quality.
PLAISIR - Planning Innovation: Learning form socially innovative energy projects
PLAISIR analyses social innovation in energy projects located in peripheral region in order to understand their role in energy transition processes and to give recommendations for energy-oriented, endogenous regional development policy.
PRoBateS - Potentials of planning and building legislation for energetically sustainable city structures
The aims of this project are to analyse planning and building legislation in order to identify barriers, potentials and suitable courses of action for energy-orientated policy measures. Specific policy recommendations are developed with a view to increasing the sustainability of energy-related city structures. For these purposes the project combines two different disciplinary approaches: a thorough legal analysis and a spatial structure and quantitative impact assessment.
PVOPTI-Ray, Optimization of reflecting materials and photovoltaics in urban environment with respect to energy balance and bioclimate.
Within the scope of the project PVOPTI_Ray the influence of reflection and energy balance on the performance of building integrated photovoltaics (PV) in complex urban environment have been investigated. Equally the influence of PV modules and of the energy conversion of solar energy at the PV module surface has an impact on micro climate and therefore also on pedestrians who are exposed to the radiation fluxes. This was also investigated.
