final review_solar-tower-plant

waking up the sleeping giant


the main idea is to lighten up the building and transform its appearance into a remarkable icon, a vivid landmark at the pireaus harbour, that represents the gate to modern Athens.
the sun always played a central role in ancient as well as modern greek culture. In the Greek mythology it was Helios, the god of the Sun, whose task was to drive the solar cart across the sky.
today modern technology has replaced the explanation, but the sun always was and still is driving the Greek and mediterranian climate.

this concept for Piraeus Tower‘s new facade is based on the sun‘s diurnal and annual path accross the sky, combining optimized illumination through light performing systems and shading
in order to save energy for cooling systems and artifical lighting. The concept does not only rely on passive shading devices, but on the active use of solar light and solar power.
the Piraeus Tower‘s new facade and its revitalized public accessibility will transform it into a bright shining symbol for the efficient use of solar energy.
not only by making use of quite a lot already well known concepts, but by literally visualizing the concept through its enlightened exterior, educating its visitors by astonishment.

the new facade of Piraeus Tower is activated to use the entire spectrum of solar power.
versatile like a gecko skin, there is one general element, implemented on a irregular grid, which is able to react differently to the local solar radiation,
depending on its precise position, function, and the sun‘s diurnal and annual angle.
the element geometry in particular,  is parametrically transformed in three solar power systems, such as redirectional light shelves, photovoltaic cells and parabolic reflectors.

parametric strategy

the main element is a simple twistet shape. a versatile vector is responsable for he exact geometry.
it changes its geometry depending on its function.

specifiction of solar-elements:
1. solar concentrating  paraboli- trough elements

2. solar collecting photovoltaic cells

3. redirecting light shelves

these elements are implamented on an irregular grid, which is deformed by attractor curves.

the designprocess is led by the appearance of the regular irregularity of a gecko skin, which is able to embed different functions and geometries in one uniform pattern.

1-6 describe the general design process.
attractor curves are disturbing the regular grid (1-3),
in which  the elements are implemented (3-6)
