Evaluation of a web-based survey on mold growth and prevention (2013): An important task of Vienna’s Municipal Department 39 is to advise citizens on mold growth and prevention strategies. To evaluate the frequency of mold in Vienna, a web-based survey was developed. With this instrument the personal risk potential could be determined by residents based on their usage behavior and characteristics of the home, and feedback given immediately at the time of the survey. more
Ecological Optimization of the Thermal Insulation of Buildings (2013): In this project the reduction of ecological impacts due to the higher thermal quality of the building envelope was calculated for natural gas, light fuel oil and wood pellets and compared with the higher impacts due to the required greater thickness of the insulation, using EPS (expanded polystyrene) as an example for an insulation material. more
The Urban City and Residential Development - A New Urban Renewal (2013): The aim of this research project is to establish measures and interventions for the improvement of the living spaces provided by existing residential projects dating back to the 1950s and 1970s and examine the extent to which density can represent a relevant concept within the context of urban planning and residential development policies. This includes an assessment of the possible degree of effectiveness re-densification measures can achieve. more
Growing Inwards. Growth potential of Vienna’s Gründerzeit districts (2013): Gründerzeit districts, along with the peripheral expansion areas, have to provide an appropriate contribution to urban growth. This requires the development of effective strategies for creating new living space by refurbishing, extending lofts, and adding storeys, as well as for preserving and creating affordable and easily accessible housing. more
