There are 130 results.
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.
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.
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.
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.
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).
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.
Elaboration and programming of a software that reduces effort and time consumption of Passive house and Plusenergy house planning. By developing direct interfaces between CAD-applications and PHplusCAD and interfaces between PHplusCAD and Passivhouse planning tools based on MS Excel the system could be improved and the related working processes alleviated.
It was the aim of this project to make a technology leap in the safe and realistic detection of DC arcs. In reality the variety of conditions of ignition is huge and therefore not covered by the standards and most available products. The focus of this project was the research of conditions of ignition, to derive new detection methods based on the outcomes.
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.
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.
Development of new manufacturing technique for photovoltaic solar modules, which fulfil the special requirements of building integration.
The overall objective of the present project is to develop and implement an optimal overheating protection system based on polymeric materials. The aim is to reduce maximum room temperatures in buildings caused by facade integrated solar-thermal collectors in stagnation.
