LessIsMore - Energy efficient human centric lighting by innovative components and daylight integration
Human Centric Lighting (HCL) is focused on the positive visual and non-visual (biological) effects of light on humans, but is wasting energy by the inefficient use of components and daylight. In LessIsMore an exemplary pilot installation will be developed and evaluated.
The project LINE-FEED develops technologies that are required for a photovoltaic storage system which can be installed by anybody by simply plugging it into a wall socket. The aim is to create a storage system for households in urban areas that do not have the possibility to install a photovoltaic system themselves.
Application of the prototype in the operational environment for a period of 20 months. Technical monitoring thoughout the cycle of seasons, user interviews concerning satisfaction, evaluation of the potential use of LooPi material streams as soil conditioner for organic farming. Results serve the development towards market maturity.
Highly energy efficient presence detectors, control systems for sun shades etc. are de facto not available on the market. Regarding plus-energy office buildings, the minimisation of the power consumption of these components is a central criterion to achieve the "plus" part in terms of the energy of the building. A highly energy efficient presence detector was successfully sketched in this project, which undercuts the intended standby consumption of 0,05 W.
LTS Flywheel - Long Term Storage-Flywheel: New approaches for increasing the economically usable storage time and safety
Development of the fundamentals for a Long Term Storage (LTS)-flywheel for decentralized storage of electrical energy (e.g. from wind or PV power plants), with a significant increase in storage time (goal: 12 hours) and safety, featuring low system costs. Therefore, the LTS-Flywheel is an essential contribution to the building of the future.
Optimized & reliable operation of Heating, Ventilation and Air Conditioning (HVAC) systems in terms of maintenance and energy management, using predictive, data-based & self-learning error detection. Conceptual design and prototype implementation of an AI (Artificial Intelligence) tool for automated data analysis and recommendations for technical building operators.
Analysis and implementation of alternative ventilation systems for windows, focusing on thermal renovation of old buildings. The investigated ventilation systems were presented to an expert group. The aim was to discuss ventilation technologies with the help of different aspects and to develop a SWOT analysis.
MehrWertStrom 2030 - PV-Community system - Exploring a participatory pilot project with regional added value for structurally weak regions
The "MehrWertStrom 2030" project analysed the legal, technical, organizational and economic feasibility of PV community joint venture facilities on multi-party buildings including the added value for structurally weak regions and developed innovative solutions related to organization, financing and realization.
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.
A robust, predictive controller which utilises weather forecast data to control thermally active building systems had been designed, researched and assessed in terms of energy efficiency and comfort compared to standard controllers, especially for cooling purposes. Simulations and real measurements using two "Test-Boxes" with thermally active building systems which are constructed and built for this purpose were used to analyse energy efficiency and comfort. Low complexity and transparency of methods and solutions should allow for transferability of all results to guarantee maximum usability for similar applications.
Concerning to an accurate and adaptable construction of 2 to 4 storey solid timber houses with the characteristics of a passive house, a digital construction and dimension system will be developed. The system which contains standardised modular ecological detailed solutions enables an exact dimensioning and installation of passive houses by small carpentering companies.
This project addressed the development of construction details for the implementation of vacuum glazing panels in new windows. In this project such constructions (form of frame, thermal bridges, structural aspects, mounting of glass) were explored via empirical experiments and via simulation. As an outcome, a mock-up was constructed, and the findings were documented in a comprehensive document.
Multi-WP – High-efficiency multivalent heat pump concepts for the thermal use of external air with geothermal storage
Optimization of multi-WP systems consisting of air-source heat pumps and geothermal storage with regard to increasing flexibility and efficiency from 30 kW for individual buildings as well as neighbourhood solutions and addressing aspects such as PV utilization optimization, mode of operation, utilization conflicts and noise pollution from air-source heat pumps. The project will establish the use of the heat source external air in combination with seasonal storage as a particularly efficient alternative for heating, cooling and hot water supply.
Development for the application in the passive house standard (e.g. low-energy houses).
The "oh456 Plus Energy Office Building" with its adjoining small hydro-electric power plant shall serve as a prototype for testing innovative technologies and also provide the companies residing in the building integral home surroundings comprising common break and leisure facilities. A wide public will have access to the building which will be a location for the most diverse events, exhibitions and lectures on climate protection as well as being a joint promotional platform for sustainable construction.
OptiMAS - Optimization of building energy efficiency through model-based energy flow analysis with non-invasive sensors
Using a model-based energy flow analysis supported by non-invasive sensor technologies OptiMAS investigated how to monitor, analyze and optimize existing buildings independent of the installed HVAC systems and automation components. With the OptiMAS approach the optimization potential of individual buildings up to entire areas can be detected, located and tapped by adjustment of system parameters to ensure highest energy and resource efficiency.
Optimisation of ecological construction components for industrial serial production of precast elements
The project focused on passive house elements from straw and clay. Special interest was paid at a novel straw insulation as well as at an efficient drying process of the clay. Sustainability of the building materials was a very important aspect within the project.
The necessary efficiency of modern energy-self-sufficient buildings can only be achieved with intelligent control of the key parameters. The main focus of the project is the adaptation of optical sensor concepts for application in building technology. The future goal of the project is to supply the modern energy-plus-house with an appropriate and intelligent control device to minimize energy loss.
The research project Peer2Peer im Quartier deals with applications optimizing the selfconsumption of PV-generated energy within urban quarters by enabling peer-to-peer relations among energy prosumers based on Blockchains. Aim is to develop and validate these applications in real operation.
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.
