In this project such constructions (form of frame, thermal bridges, structural aspects, mounting of glass) were explored via empirical experiments and via simulation. As an outcome, a mock-up was constructed, and the findings were documented in a comprehensive document.
lowTEMP4districtheat - Reduction of the system parameters of heating networks for the integration of renewable heat sources using soft sensors
Analysis of the use of soft sensors in addition to selective real measurements for the complete recording of real-time parameters of heating networks. The data obtained enable detailed grid simulations with low computing power requirements and form the basis of a strategy for lowering the grid temperatures and feeding in decentrally generated heat.
The feasibility of daylight-optimized solutions for retrofitting courtyards by an intelligent alignment of different materials has been examined. With it, daylighting levels in lower floors can realistically be increased tenfold. Additionally, a calculation tool for generating and evaluating optimal courtyard solutions was designed. Besides daylighting parameters also economic criteria were considered.
SUBURBAHN – test- and demonstration-area for urban development and mobility around public transport stations in the central area of Upper Austria

In "Enerspired Cities" the concept for an automized junction of judicial secured access regulation to (geo-)energy data is elaborated. This will be adapted to the specific situations in the cities of Innsbruck, Salzburg and Vienna and implemented in dedicated pilot applications. The declared aim is the support of urban planning, monitoring and research by an easy and transparent access to base data coming from various sources for a wide range of users.
Development of systems for the emission-neutral cooling of office, research and urban quarters on the basis of photovoltaic or geothermal energy supply and user integration. Life cycle cost calculations and analyses of grey and operational greenhouse gas emissions allow a holistic assessment.
Development of testbeds and demonstration zones within already designated areas for urban development along the Graz-Gleisdorf Innovation-Axis with a focus on energy, integrated building technology, smart city-spaces, compact settlement structures, generational living, and ‘cities of short ways’. It will pay specific attention to intermodal mobility as well as ICT-based solutions.

urban pv+geotherm - Innovative concepts for the supply of large volume buildings/ quarters with PV and geothermal energy
The use of renewable energies in inner city locations is mostly linked to higher costs andconsidered as problematic. The aim of this project was to optimize (cost and energy) heating (and where required, cooling) using geothermic and photovoltaic for an urban, densely-built development area. With the project´s findings it will be easier to ecologically and economically plan the use of renewable energies especially in urban areas.
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 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.
In the course of DALEC an online concept evaluation tool for architects, building engineers, lighting designers and building owners was developed. Although easy to use, the software accounts for the complex thermal and light processes in buildings and allows a simple evaluation of heating, cooling and electric lighting loads. Not only energy, but also user behavior were considered (e.g. in terms of glare protection) and visual and thermal comfort were evaluated. This novel and innovative, holistic approach makes sustainable and energy efficient building design possible for new buildings as well as refurbishment.
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.
Possibilities and requirements of transferring the Swiss “2000-Watt Site” certificate to Austria
Sensible storages, which are currently used in district heating networks for seasonal storage of excess heat (e.g. from solar thermal or industrial waste heat), exhibit high space demand, investment costs and heat losses. Within this project, concepts for using innovative storage technologies, e.g. thermochemical storages (TCS) having high heat densities and enabling pressure- and lossless storage, were developed and analyzed on a technological, economic and ecological basis. Additionally, the regulatory framework has been evaluated.
InnoGOK – Investigation of the energetic and ecological usability of solar radiation on urban spaces and paths
Examination of the suitability of street space or other paved or not paved surfaces in urban areas for promoting renewable heat from solar radiation. Thus offers a high potential for increasing energy efficiency and conserving resources in urban contexts. Besides, the dissipation of heat from large solar-heated surfaces promises to prevent urban heat islands.
baubehoerde.at - Development of a Vision 2030 for a Digital Building Authority and Recommendations for Action in Austria
In Austria, planning permission applications are submitted and managed largely manually. The aims of the baubehoerde.at project are to evaluate the potential and limitations of digitizing building approval processes and to create a Vision 2030 strategy for a digital building authority.
Assessment of the potential for pre-commercial procurement in the Smart City energy sector in Austria in the areas of innovative building technologies, urban energy systems and systems for urban planning. The results will serve as the basis for recommendations for future priority setting for public procurers.
The objective of this research project is to design a methodology for developing data and process models and to apply them by modelling selected MEP systems. A particular but not exclusive focus is put on the renewable heating technologies, e.g. heat pumps, solar heat and biomass as well as ventilation systems. The data and process models developed in this research project will be scientifically evaluated in two pilot projects. The models, the approaches taken during development and the project team’s experiences with the pilot application of the models will be disseminated openly.
