Pre-cast cantilever balconies represent a particular problem in the thermal renovation of buildings. The central goal of this project is the development of practical and cost-effective mounting solutions for the thermally decoupled reconstruction of balconies on building frontages and achieving a significant increase in the energy performance of the thermal renovation measure.
Pre-cast cantilever balconies represent a particular problem in the case of thermal rehabilitation of buildings. With the THERM-opti-BALKON-System a solution is currently being investigated under laboratory conditions. Phase 2 aims to create an in-situ-pilot-station. The most important object of study is the long-term behavior of the THERM-opti-BALKON-System.
In the course of the project FFF-TaliSys novel daylighting systems based on freeform surface technology are developed and implemented into functional models, thus, innovative systems that solve the contradictory requirements of daylighting systems. The aim is to develop systems for façades and skylights that yield optimal visual and thermal functionality, but work without moveable parts and complex controls.). For the integration into the building skin as well as the optimization of the optical systems both thermal and visual boundary conditions are taken into account. Thereby, energy-efficient solutions shall result, which guarantee highest visual and thermal comfort in new and retrofitted buildings.
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.
The project "Urban wind energy" aims to create the basis for the assessment of roof-mounted small wind turbines (SWT) in urban areas. Therefore, methods for the characterisation of turbulent wind flow fields are developed and on the other hand the impacts of turbulent wind conditions with reference to selected turbulence indicators on the performance of small wind turbines are investigated. The overall aim of the project is to address the question how to evaluate sites in urban areas for the application of small wind turbines.
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.
Syn[En]ergy: Development of Potential Synergy Effects between the Interdependency of Urban Planning goals and Photovoltaic Usage on Open Urban Landscapes
Open spaces such as parking lots, brownfields and some categories of recreation areas offer an underutilised potential for photovoltaics in urban regions. In the course of Syn[En]ergy an inter- and transdisciplinary approach potential synergies and conflicts with other use demands were investigated, a typology and practical solutions for selected areas with regard to requirements from economy, urban planning and design, legal as well social aspects developed, and then evaluated by stakeholders from enterprises, administration and the general public.
Within this project the intensive use of thermally activated building elements (TABs) as an additional thermal storage in different buildings, with solar technologies (thermal, PV) preferred for energy supply, was investigated. The aim was to activate and use the thermal storage potential that is immanent in the building elements and thereby achieve solar coverage of the building's heat demand of nearly 100 %.
The aim of this project was to advance the state of the art in the engineering of double-leaf building facades that facilitate natural ventilation while providing sufficient sound insulation. Realization of natural (window) ventilation is in some instances difficult due to a number of factors. Thereby, noise pollution (especially traffic noise) plays an important role. To address these issues, the project explored innovative solutions in terms of facade constructions for concurrent natural ventilation and noise control.
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.
Research on the influence of collector hydraulics, piping and the arrangement of plant components on the stagnation behaviour of thermal solar systems.
AGelFa - Development of surface structurable final-coating stucco systems on high-performance heat-insulating aerogel insulation plaster for historic building facades.
High-performance insulating plaster systems represent an important option toward improving the thermal insulation of historic buildings without changing their physical appearance. The high-performance aerogel insulation plaster has recently become available for deployment. In this context, the present will explore final stucco systems suitable for building with structured surfaces.
Improvement of operational parameters (efficiency, quality of current waveform, reduced size and weight) and reduction of manufacturing costs
The main objective of the key project "e80^3" was to develop high-performance renovation concepts focusing on plus-energy-buildings. Afterwards these concepts were realized in at least one or two demonstration-projects.
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.
Whiscers is a system for installing internal wall insulation with minimal mess, whilst the resident remains in the property. It involves measuring the walls in the property using a laser device that enables fast and highly accurate measurement. Information is then sent electronically to a computer controlled off-site cutting machine that is rapid, precise and mess-free.
CellPor - cellulose polymerized - new methods for the processing of a polymer-cellulose-foam according to ecological criteria in construction
The development of a spray applicable cellulose composite as insulating material on the basis of renewable resources, combined by the development of a prototype for the spray-on technology for processing the new, water free cellulose composite are the demanding challenges of this project.
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.
FM.Comfort/FM.Ware - Software for optimizing the use of energie and other resources in the virtual house
The expert system FM.Comfort/FM.Ware realizes the so called virtual house (vh). The virtual house is the computer model of a real building. This computer model supports the optimization of the use of energy and other resources by analysis of the life and work habits of the residents and the positive influence on inhabitants-behaviours (user motivation).
