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.
ecoRegeneration: Development of a "Merit-Order" in order to assess regeneration heat for geothermal probes within urban residential neighbourhoods
In urban residential areas there are not enough active-cooled usages, to use the waste heat of the cooling process as required regeneration heat for geothermal probes; free cooling of the apartments is not sufficient. The project is developing various options (waste heat from commercial uses in the ground floor zones of residential buildings, by using waste heat of data centres, additional installation of heat generation systems for regeneration) within the urban settlement area, business models and is calculating life-cycle-costs of all solutions. The result should be a kind of "merit order" for regeneration heat.
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.
Multi-Activ-Facade
Multi-Activ-Facade is a pre-manufactured, multifunctional panellised façade, which incorporates ventilation with heat recovery, passive house windows and photovoltaic for smart self-supply within retrofitting measures. The specific challenge is the application within social housing.
SocialLowCostFlex - Collaborative flexible low-cost energy supply concepts for social housing
This project aimed for feasible low-cost solutions, which allow residents of multi-party houses, with special focus on social housing to profit and participate in the energy transition process and associated trends (e.g. community generation units, exploitation of flexibility). The results of the project are low-cost concepts and business models of community generation units and utilization concepts, tested for their feasibility in a social housing complex. These concepts are based on special requirements of different lifestyles in low-income households and take the framework of social housing such as tenant fluctuation into account.
PEB - Plus-Energy-Office
An integrated technical energy plus office concept without additional building costs demonstrates the feasibility of such projects instancing a concrete office project with 50.000 m² floor area in Vienna with economical cost consideration.
Monitoring Sunhouse Eferding
In course of the monitoring project the effectiveness of the energy-technical system was checked on the basis of running measuring data. The data were evaluated and, if required, the arrangements and settings of the control system were adapted. Main result is that the energy balance could have been improved explicitly whilst the monitoring process.

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.
