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.
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.
P2PQ - Peer2Peer im Quartier
The research project Peer2Peer im Quartier deals with applications optimizing the selfconsumption of PV-generated energy within urban quarters by enabling peer-to-peer relations among energy prosumers based on Blockchains. Aim is to develop and validate these applications in real operation.
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.
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.
PV-Arc Detection - Circuit supervision using DC-Arc Detection in PV systems on dwellings.
It was the aim of this project to make a technology leap in the safe and realistic detection of DC arcs. In reality the variety of conditions of ignition is huge and therefore not covered by the standards and most available products. The focus of this project was the research of conditions of ignition, to derive new detection methods based on the outcomes.
PV4residents – Innovative Finance Service and Business Model for PV Power Plants of Multiple Dwellings with On-site Use of Electricity
The aim is to develop a business model, which enables a stronger penetration of PV plants on multiple dwellings with self-consumption of produced electricity by the residents. Involvement of the municipality allows to deliver surplus electricity for their needs. Basis of the business model is an analysis of the technical, legal, administrative, user related and economic barriers with participation of stakeholders and to identify best practice solutions.
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.
ParaSol - Multifunctional solar canopies for urban streets and places
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.
PersonAI - User-Centered AI-based energy services built on personal preference models
Conduct a large-scale, long-term study with 40-50 people to create personal comfort profiles to increase comfort in buildings. The personal comfort profiles will then be fed back into the building control system as input variables in a proof-of-concept.
PhaseOut – Heat pump technologies in the renovation of existing buildings
The aim is the conception, optimization, implementation, demonstration and evaluation of innovative, minimally invasive renovation solutions (thermal renovation and heating system replacement) with heat pumps and PV in multi-storey buildings on seven identical buildings.

Photonic Cooling – Efficient cooling of buildings through the use of photonic
Within the scope of the project a photonic cooling approach was investigated and evaluated in terms of feasibility and cost efficiency for building applications. In particular cost-efficient photonic surfaces and concepts were investigated which need to have a high reflectivity in of the incident solar radiation (>97%) and a high emission coefficient within the spectral range of 8 – 13 micrometer in order to enable the emission of heat into the sky.
