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.
GameOpSys - Gamification for optimizing the energy consumption of buildings and higher-level systems

The "greening UP!" Knowledge pool with concrete recommendations and clearly presented findings as well as the conception of a digital tool for the "First Green Aid" complete the project.
PowerShade - Development of electricity-generating shading solutions for energy-flexible buildings in urban space
The main goal of the cooperative R&D project "PowerShade" is the development of low-cost and universally usable electricity-generating shading solutions for energy-flexible buildings in urban space.
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 project deals with applications optimizing the self-consumption of PV-generated energy within urban quarters by enabling peer-to-peer relations among energy prosumers based on blockchain technology. The aim is to develop and validate these applications in the field being used by consumers.
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.
The core of the project P³Power is the measurement technology NetDetection, which is able to detect the power consumption of a household from any point, e.g. a regular wall socket. Based on this technology a plug&play powerplant, consisting of photovoltaics and battery pack, is realized. The system is able to guarantee 100% self-consumption within flexible aggregates (from single households to whole communes) without any changes of existing infrastructure. The measurement technology will be implemented into digital hardware, evaluated comprehensively in lab and household environment and subsequently new energy service business models are developed.
SPACE4free - Retrofitting souterrain areas in 19th century townhouses to apartments with high quality of life and low energy consumption
Planning of durable and damage-free apartments with high quality of life and low energy consumption in moisture exposed souterrain areas of 19th century townhouses. Using innovative ventilation control systems comfortable room climate will be created. Additionally the tolerance of different types of use is ensured. A planning tool enables the scaling of the findings and thus the applicability to various planning situations.
The aim of this research project is the development of a construction site-suitable augmented reality (AR) system included a Remote-Expert-System and a BIM-Closed-Loop data transfer system for improving the quality of construction, building security and energy efficiency as well as increasing the efficiency of construction investigation.
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.

Development and simulation of scalable, distributed control strategies for the use of the storage effect of thermally activated components in buildings of future city districts for their energy supply by an energy centre.
The integration of heat pumps can increase the cost effectiveness of existing heating networks and counter the high costs for the expansion of power grids at the same time. Aim of the project is to develop innovative business models for small and medium municipal heating networks with focus on synergies between heat and power market. Main focus is a heat pump pooling for several heat grids.
Innovative, dynamic control concepts shall be developed which enable (air) heat pumps in combination with PV- or renewable grid electricity to use the building mass of a multi-familiy house as heat storage. User acceptance shall be evaluated and possible business models shall be developed.

User behavior is a key factor for the energy consumption and the actual energetic performance of a building. A new type of user feedback system will be investigated in this research project. Users provide feedback on the sensed room quality. The data obtained by the feedback system are used to optimize settings of building services in order to improve the energy efficiency and the comfort in the building. A basic proof of concept of this system will be undertaken by means of two use cases.
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.
