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.
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.
The objective of this research project is 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 are developed and evaluated on the basis of four typical use cases.
This project aims 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.
ÖKO-OPT-AKTIV - Optimised control and operating behaviour of thermally activated buildings in future urban districts
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.
EnerPHit-green concept Modernisation of a historic building with application of an aerogel insulation plaster
This demonstration project shows the comprehensive modernization of a historic building within the constraints of a regional protection zone. By using the Aerogel high-performance insulating plaster, a comprehensive energy-efficient building refurbishment had been realized without changing the outer appearance of the façade.
Sol4City - Integrated solar supply concepts for climate-neutral buildings for the "city of the future"
Intelligent technology coupling to achieve high solar coverage of the buildings (multi-storey residential building) heat and electricity demand. At the end of the project, integrated energy supply concepts for multi-storey residential buildings based on high network interaction and flexibility potential, maximum surface efficiency of conversion technologies on site and high economic competitiveness are available for the broad applicability in the "City of the Future".
The goal of FitNeS is the development of modular split heat pumps with compact and silent façade-integrated outdoor units for heating and domestic hot water preparation (and optionally cooling in combination with PV). The outstanding features of the concept are a modular design with a high degree of prefabrication and representing a visually and architectonically attractive, economic and sustainable solution for both new constructions and renovations. One of the main development goals is the minimization of sound emissions by means of optimized flow control.
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.
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.
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.
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.
