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.
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.
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 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.
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".
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.
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.
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 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.
With the city of Leoben as a use case this exploratory project will, for the first time ever, examine the spatial effects, synergy- and energy potentials of newly developed wide-span light-weight solar canopies for streets and squares in urban public space as well as their implications on the townscape, the image of the city and the city function.
Piezo-Klett: Development of piezoelectric hook-and-loop application for the energy supply of active sensor technology in the building industry
The present project considers buildings, parts of buildings and their joints (component nodes) as energy generators by using the hook-and-loop fastener in combination with the piezoelectric effect to perform a so-called energy harvesting.
The present project is based on the results of the project "The energy-efficient hospital: realistic departure points and identification of possible measures"
This project examines opportunities, potentials and requirements of/for Agrophotovoltaic systems. Thereby, an interdisciplinary study will be conducted that integrates the major aspects of such systems holistically and from an integrative perspective. The complex interdependencies between the different aspects will be explored and described via a case study. Potential approaches toward realization will be studied and subjected to a comprehensive SWOT-analysis.
ProKlim - Optimisation of Energy Efficiency of automated indoor climate systems by using weather forecasts
Investigation of the basic energy savings potential for buildings in commercial use by including weather forecasts as a variable. Additionally, a concept for integrating weather forecasts into the heating and air conditioning control systems in buildings is planned to be developed. Within the scope of the feasibility study, a detailed analysis of technological possibilities, including both hardware and software, will be conducted.
This evaluation will examine the effects that the "City of Tomorrow" programme has achieved since its inception. The evaluation is based on extensive surveys of research project participants and various multipliers from application areas such as civil engineering and urban planning. The evaluation thereby creates an important basis for the design of future research funding.
R-Bau - Development of a replicable deconstruction strategy for residential buildings to force the recovery-oriented dismantling
The aim of the project was to develop a replicable deconstruction strategy for residential buildings to force the recovery-oriented dismantling. The key aspects of the project are the development of standardized building models in order to analyse the recovery-oriented dismantling process, the design of a deconstruction catalogue and the transfer of the project findings to refurbishment, design and erecting of residential buildings.
