LIGHT + TECH 135
the week, divided by pathways accessible to the public. Each of these segments has 24 columns to represent the number of hours in a day. As time passes, the hour column glows, suggesting a countdown to addressing the current climate urgency.
The column also acts as a ‘metabolic element’. From top to bottom, it comprises light cones, parametric solar fins, horticulture pods, vertical gardens and energy reservoirs.
The greenery growing around and up the columns, together with the shading from the solar fins that branch off the columns below the light sources, makes the installation a conducive social space. Diff erent elements in each of the segments are designed to encourage diff erent responses from people. The design and positioning of the installation responds to both local parameters and existing street compositions, as well as incident radiation, which is calculated to capitalise on the position of the sun during the summer months, starting from April to October.
The geometry of the clock segments
is further optimised to maximise their radiation exposure. While 24 of the hour columns are organised in the same pattern for each segment, the modulations and resulting variations of the algorithmically optimised geometry are reflected in their diff erent heights. The solar fins, which will automatically adjust to maximise sun exposure, are made of multi-junction solar cells that have a higher conversion ef iciency than that of traditional photovoltaics. The conversion ef iciency arrived at by Mandlik is assumed to be 42.5% (theoretically 87%) ‘to reflect a real-life scenario’. The ground area houses energy reservoirs and their connections with the city grid. The estimated energy that the installation will generate (1,077.6MWh) is therefore based on calculating 42.5% of the annual incident radiation. Each segment of the pie will actually vary slightly in the energy it generates (between 11.5% and 16.4%). Around 67% of the total energy produced is directed towards the city grid, supporting approximately 200 households based on the average household consumption of 3,500kWH, and the remaining 43% is used by the proposal itself.
However, partially filtered wastewater is drawn from the city grid for the maintenance of the vertical gardens and to aid the process of plantation growth from seed to the sapling stage, housed within the horticulture pods. Of the 43% of self-used energy, 28% is used for vertical farming processes, 11% for the rotatory motion of the solar fins on activation, and just 4% for the light cones.

The installation is aligned with key UN Sustainable Development Goals, including ensuring well-being, promoting access to sustainable energy, and combating climate change.
