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.
CityStore - Sondierung des wesentlichen F&E-Bedarfs zur Optimierung von städtischen Energiespeichern in integrierten Energiesystemen
CityStore pursues a first-of-its-kind, innovative approach on spatial location of storage needs and potentials. This includes the evaluation of concrete challenges and prerequisites as well as the identification of useful storage technologies and capacities. Model calculations for the model cities Graz and Weiz will be carried out. If, and to which extent, the results can be generalized will be investigated in the Follower Region South Burgenland. The results should enable optimized planning and realization of urban energy storage facilities – thereby enabling targeted investments in energy infrastructure to achieve (local) climate and energy targets.
Climate Hub Vienna - Concept development and preparation of an innovation laboratory to accelerate Vienna’s path to climate neutrality
Preparation of an urban innovation laboratory to support decarbonisation in Vienna by 2040. The focus is on systemic innovation and accelerated roll-out of RTI projects through infrastructure, services, networking and the systematic involvement of city administration and users. The innovation lab is intended to strengthen the effectiveness of innovations and the participation of the Viennese in the transformation.
Climate-School-Life - Preparation of the climate-neutral educational campus in Gratwein-Straßengel
The project aims to start the transformation process of the educational campus of the market town of Gratwein-Straßengel into climate-neutrality. The need for the expansion and modernisation of the elementary school forms the central part of this development. The project provides an integrated district concept for the four central infrastructure topics of the project: urban development, architecture, mobility and energy. Participation processes of the population and innovative financing models are further components of the exploration.
Co-Housing Gutenberg: Integrated Sector Coupling for Shared Living, Energy, and Mobility
The "CoHoGutenberg" project aims to establish a sustainable co-housing model in the rural community of Gutenberg, Styria, by combining sufficiency principles with state-of-the-art energy technologies.
Cool Windows - Windows with shading optimising the trade-off between summery overheating, wintery heat protection and adequate illumination
Windows with their associated components such as sun and glare protection are optimised as a holistic building equipment unit regarding different seasonal requirements in light of the climate crisis. The results serve as a basis for new developments in the window and shading technology in order to provide summery and wintery heat protection as well as adequate natural illumination over the year.
CoolAIR - Predictive control of natural nighttime ventilation and daylight-optimized shading for passive building cooling
Natural nighttime ventilation and daylight-optimized shadowing are high potential approaches to efficiently and economical cool buildings. Nevertheless, the full potential cannot be acquired, since, if at all, such behavior is manually initiated by users. Goal of this project is the development of an automated, self-learning system that can assess the full cooling capabilities and establish an alternative to conventional air conditioning systems.
Cooling LEC - Energy-flexible buildings by controlling cooling systems via unidirectional communication in local energy communities
As a result of climate change and the rise in temperature, especially due to the increase in active cooling systems, especially at low-voltage level, new challenges are being posed to the electricity system (in particular to the distribution network). Due to the high electrical input of active cooling units and the high density of plants, which are sometimes operated uncoordinated and at unfavorable times, leads to peak consumption in the system. The project Cooling LEC therefore has as its overall objective the development and demonstration of a central control / intelligence of decentralized active cooling systems by further developing the unidirectional communication of ripple control systems to create energy-flexible buildings in the sense of the new approach of "Local Energy Communities" by creating a "special tariff". Ripple control systems have been established for many decades and are available and proven by all energy suppliers. The upscaling potential is very big.
Cooperative Living Volkersdorf (KooWo - Volkersdorf) - sufficiency, space and energy efficiency in the quarter
The jointly planned demonstration project "KooWo" in Volkersdorf aims at reaching sufficiency as well as energy and CO2 reductions in a holistic way. System boundaries are shifted in order not to look only at energy consumption in buildings, relating to unit of floor space, but to consider all use of resources and relating it to persons and social communities.
Counterintuitive Building Types - Innovation Potentials for Sustainable Transformation of Commercial and Retail Locations
Selected commercial retail and properties provide existing resources for this project’s case studies that will convert and further develop them towards more positive energy, use, and life cycle balances. The currently underperforming properties will be transformed into more active and attractive places of higher experiential density and environmental relevance through multiplication of space and uses in the interior and exterior areas, demonstrating opportunities for more sustainable development of these understudied building typologies.
DALEC - Day- and Artificial Light with Energy Calculation
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.
