Heat Harvest - Harvest of urban solar excess heat from buildings and surfaces to avoid summer overheating in cities

"Harvest" of solar urban excess heat from building surfaces, sidewalks, streets and squares to avoid urban heat islands by lying flat absorber pipes, which are then fed into geothermal probe storage tanks for later use as a source for heating buildings.

BIMBestand - BIM-based management of existing buildings

The objective of this research project was to develop information requirements and process descriptions for the application of BIM models related to building services in facility management and to demonstrate the lifecycle-oriented use of these models in an open BIM environment. For this purpose, software solutions for the use of IFC in the open-source platform SIMULTAN and building management software were developed and evaluated on the basis of four typical use cases.

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.

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.
