The potentials of photovoltaic elements in an urban context of the near future

Stefan Diez & Christian Steiner


While photovoltaic systems on roofs in rural areas or on agricultural fallow land are becoming more and more widespread, PV systems in urban areas have hardly been realised so far due to building regulations, such as regulations for the protection of historic buildings, or simply because of the ownership structure of buildings in cities. The situation is similar in public places, where it has also not been common practice to use PV systems to generate electricity.

This is tragic insofar as there are plenty of facades, roof surfaces, streets or squares available in cities that would be suitable for the generation of solar electricity and whose photovoltaic activation would not be in competition with agricultural areas, fallow land or nature in general.



What would it be like to use photovoltaics in cities, either as an integrated part of the existing building stock or in public spaces such as parks, bus stops, kiosks and bicycle stands, while at the same time having an innovative and aesthetically positive impact on the cityscape? What if photovoltaics were to become an integral part of the cityscape, spreading across all buildings in the cities? What storage options for solar power would be conceivable in an urban context? What if the planning of such elements were to take place in the municipal context (and no longer be in the hands of the building owners)?


The SUNNY GROUP will work closely with the manufacturer of organic solar cells - ASCA - , but will also work with conventional solar modules and develop visions that put a forward-looking, self-confident usage of solar energy in our cities at the centre of their efforts.


With the support of ASCA and SYNDIKAT WALDEN, your visions can be realised and experimentally tested in the form of prototypes.



According to Greenpeace, a central European currently emits an average of 12 tonnes of CO2. However, in order to achieve the goals of the Paris Climate Agreement, which limits global warming to 1.5 degrees Celsius, each person would have to get by with only 2 tonnes of CO2 per capita per year.

The construction sector is responsible for more than a third of the world's energy consumption and more than a third of the world's waste. This now puts enormous pressure on the building sector to save both materials and energy.

At the 2014 Venice Biennale, architect Rem Koolhaas showed in an impressive exhibition how designers, engineers and craftsmen work together to design the elements of architecture. These semi-finished products have been designed for centuries with an awareness of a coherent whole - both at the level of the building and at the level of the cityscape.
With the Paris Agreement, the guidelines for architecture are now changing fundamentally, and so are those for its components. In the transformation of the building sector, architects, civil engineers and designers will therefore share the responsibility for making it a success.

So what will our utopias of sustainable living and working look like in the future if we rethink them from the elements of architecture? What role will photovoltaics play in this?

With the advent of modernism, designers and architects have repeatedly tried to express their utopia of living and working in the future through so-called CASE STUDY HOUSES. Particularly noteworthy are the works of Buckminster Fuller, Jean Prouvé, Le Corbusier, Charlotte Perriand, Lacaton Vassal, Coop Himmelb(l)au, Haus Rucker and, more recently, the works of Werner Sobeck. (See extensive research on this topic).

During the summer semester, students of ID1 designed photovoltaic elements that could significantly shape the cityscape of Vienna in the future.
In the coming winter semester 2022-23, these ideas will be further developed and then combined with the results of the other teams (led by Katrin, Elisabeth and Marcus) to form an overall picture in the form of a CASE STUDY BUILDING.

This CASE STUDY BUILDING will be presented to the general public during the Salone del Mobile in Milan in April 2023.

Examination Modalities

The grades in the subjects Design Draft 1.0 and 2.0 are made up of subaspects that are merged into an overall grade after the final presentation and submission of the image and text materials. All materials must be handed in within 2 weeks after the finals. The evaluation is completed 3 weeks after the finals.



The project RETHINKING THE ELEMENTS OF ARCHITECTURE (REOA) is designed for a period of 2 semesters. It started in March 2022 with an extensive research on the topic and will end in January 2023 with the final presentations.
A selection of the most convincing works will be shown in a group exhibition at the Salone del Mobili in Milan in April 23.

IMPORTANT: This course is also open to all students who have not yet worked on REOA. Original Briefing, Presentation, and Research

Briefing 2nd part:

Kick off for the semester project is 6 October 2022. All further dates will be published in the ID1 calendar.

Communication during the semester project will take place via SLACK and WORKBOOK. All details can be found in our STUDIO MANUAL.
