The aim of the project "DraussenDaheim - Promoting climate-neutral mobility through digitally supported scenarios of gender-just urban public open spaces" is to develop a method for the simulation-based evaluation of different planning scenarios of urban open spaces with a focus on gender-relevant groups. In particular, the question of when the green and open spaces are (should be) available to whom and with what time and economic effort they are (should be) accessible to whom is examined. The point is that space-time (policy) should be an explicit component of urban and spatial planning and its implementation in practice will be investigated. The time management concept of urban open spaces is to be developed by means of analyses, gender-appropriate visualisations and a simulation-based evaluation together with gender-relevant groups.

The project ZQ3Demo aims at developing and supporting three innovative new building districts towards Plus-Energy, in order to demonstrate sustainable and at the same time economic solutions for the implementation of Plus-Energy districts on real examples. During the project, the development and implementation of system solutions for the simultaneous optimization of the technical-economic neighbourhood goals (minimisation of CO2, primary energy and costs during construction and operation) will be supported, with the overall goal of increasing the replicability of Plus-Energy-Districts (PED). In addition, technical and sociological monitoring will be conducted and operation optimised during at least the first year of use. Due to the broad diversity of the demonstration districts in terms of function (living, working, education), degree of implementation (concept, submission, construction) and financing model (freely financed; non-profit; rent and ownership), the project addresses different issues, providing relevant results for a variety of future typologies and thus ensuring a high replication.

While large joint widths for pavements are desirable from the perspective of drainage, they are undesirable from the perspective of walking comfort and wheelchair accessibility (Grimm 2018). In the course of a master's thesis written at the Institute of Transport, the topic of barrier-free use of of road surfaces was investigated in terms of good rollability with wheelchairs (Aigner 2020). A new measurement method was developed and tested for this purpose. The basic hypothesis of the method is that there is a correlation between the objectively measurable physical quantity of acceleration and the resulting jerk on the one hand and the subjective perception of wheelchair users on the other. To test the hypothesis, a wheelchair was equipped with a mobile phone as an accelerometer. The wheelchair equipped in this way was driven over 14 different street surfaces in the city centre of Vienna and the accelerations were measured. Eleven people who are dependent on a wheelchair in everyday life drove on nine of these surfaces and evaluated their barrier-free rollability. Despite the relatively small sample, it can be assumed that the presumed correlation between physical measured variables and subjective perception exists. Accordingly, the accelerometer is a suitable method for assessing the accessibility of surfaces in public spaces. The study pursues several objectives. Firstly, the test method developed in (Aigner 2020) is to be validated in more detail and checked with regard to its possible applications in practice (WP1, WP3). Among other things, the influence of the wheelchair type and the steering wheels, which was largely excluded in (Aigner 2020), will be investigated. Based on this, a criterion for barrier-free rollability is to be derived with the help of extensive measurement tours (WP2) as a function of joint width, slab size and evenness. Finally, paving materials commonly used in Vienna will be evaluated with regard to infiltration and barrier-free rollability with the help of this criterion (WP4).
