CHALLENGE - Highly efficient use of hot gas and waste heat in air/water heat pumps for plus-energy buildings and quarters

CHALLENGE aims to further develop the system concept for air-to-water heat pumps in such a way that they can be used efficiently and without the above mentioned negative effects in densely built-up urban areas. In concrete terms, validated simulations and a functional model of the overall system on a laboratory scale are to be used to demonstrate that the concept can save 10% of electrical energy, reduce the noise of outdoor units in summer to a minimum and prevent the formation of local heat islands.

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.

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.
