Agricultural Lighting Facade: Food Producing Office Buildings

This Master’s Thesis examines the application of Agricultural Lighting Facade (ALF) for office buildings. There the question is answered how the coexistence of everyday office life and eatable plants cultivation can be optimally designed. Based on extensive research, different designs and application scenarios are developed. A prototype on a 1:1 scale enables the study on an ALF Module to be visualized and tested in practice. The acceptance of the different ideas is evaluated based on a survey where further design options are also queried. The second part of the work represents a concrete application scenario. On the example of the O2 Tower in Munich aesthetic lighting in combination with working hours, yield and consumption of salads are studied. The example of the use of ALF showed that only 1/4 of the placed ALF in the maximum scenario on the facades of the O2 Tower is sufficient to cover the consumption of lettuce by the employees of the building. That is why different variants were developed to optimize cultivation and consumption: maximum possible yield - consumption of vegetables in the area, optimized yield – occupancy by ALF of the necessary area of the facade, extension of the concept of ALF to other plant species. Finally, all findings are summarized and the further development potential of ALF for office buildings are determined.
