Ventilation and heating in passive houses: Comparison of variants in terms of thermal comfort and sustainability
This projects aims at systematic resarch on thermal comfort and the sustainability of heating passive houses with and without air heating. The results of the comprehensive investigation of different variants will provide valuable information for building developers, planners and for funding decisions.
ThinkHome is a networked controlled home of the future with the ultimate goal to optimise energy efficiency and user comfort at the same time. On this way, smart interaction between all building services is of utmost importance. Goals of this project include the definition of a comprehensive knowledge base that holds all relevant building data, the evaluation of control strategies based on artificial intelligence and machine learning, as well as agent based software engineering.
Based on four case studies the comprehensive contribution of open space to the increase of quality in real estate development was presented and provides the basis for the development of application oriented measures of quality management and strategies for innovative solutions.
In the course of DALEC an online concept evaluation tool for architects, building engineers, lighting designers and building owners was developed. Although easy to use, the software accounts for the complex thermal and light processes in buildings and allows a simple evaluation of heating, cooling and electric lighting loads. Not only energy, but also user behavior were considered (e.g. in terms of glare protection) and visual and thermal comfort were evaluated. This novel and innovative, holistic approach makes sustainable and energy efficient building design possible for new buildings as well as refurbishment.
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.
KELVIN - Reducing the urban heat island effect via improving the reflective properties of buildings and urban areas
The aim of this project was to estimate the potential to reduce urban heat islands via low-tech measures such as the variation of the surface albedo, using the City of Vienna as an example. The project has also assessed the energy savings and greenhouse gas emission reductions due to the decreased energy demand for cooling as a result of such measures.
This project targets the further development of windows with integrated vacuum glazing. Such glass products regularly feature a very low Ug-value, and their dimension is in comparison to insulation glass thin and light. As such, these products offer a new alternative for highly-insulating window constructions, and thus also for energy-efficiency measures in buildings. The project is based on the findings of a previous exploratory project (MOTIVE) and focuses on the construction of functional prototypes of vacuum glass windows together with business partners.
Knowledge consolidation of the exploratory project VIG_SYS_RENO; This project focused on the application of vacuum glass in existing casement windows for purposes of energetic performance improvement of buildings. Expected results include new insights about and a guideline for the application and utilization of vacuum glass products in existing window systems.
In the course of the project FFF-TaliSys novel daylighting systems based on freeform surface technology were developed and implemented into functional models, thus, innovative systems that solve the contradictory requirements of daylighting systems.
Intensified Density - a small scale densification strategy for the suburbs by using modular construction
The project investigated whether a small scale densification strategy for the suburbs / intermediary cities, using modular construction, and existing infrastructure on empty plots of land, can offer a competing alternative to not only the sprawl of single family dwellings but also to large projects.
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.
Multfunctional facades with integrated artificial- and daylighting systems had been simulated and evaluated regarding lighting and energy (lighting quality and energy demand). The results create basics for further façade developments and for academic education.
VisErgyControl - Integral control system for daylight and artificial lighting for high visual and melanopic comfort with minimized primary energy consumption
Within the project VisErgyControl an integral, simulation-based, energy-efficient open loop daylight and artificial lighting control system had been developed. The research project focuses on the visual and melanopic requirements of users while minimizing the energy consumption for heating and cooling.
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.
Populations with high exposure to noise emissions will generally agree: Noise means trouble. The aim of project RAARA is to develop a simple, intuitive albeit accurate method for reducing noise imissions in urban areas. This method involves placing a noise-source into its planned real-world destination prior to actual installation, by means of augmented reality. The ensuing sound-imissions are then made tangible by means of sound effects and coloured visualizations. This exceptional approach will facilitate planning for heating and cooling devices and thus reduce noise pollution in urban areas. This, in turn, can contribute to an increase in societal acceptance and investment in renewable energy.
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.
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.

SmallWindPower@Home - Impact assessment of building-mounted small wind turbines on performance, people, building and environment
Within the project SmallWindPower@Home the impact of complex obstacles on the local flow pattern as well as on the inflow and the performance of different building-mounted small wind turbines (SWT) will be evaluated. Furthermore the effects of these building-mounted SWT on the building, the resident people and the direct environment will be analysed.
