The modern urban electricity factory

Imagine producing electricity exactly where it's needed! Sounds simple, doesn't it? But in the city, it's a real challenge. The roof areas are rather small compared to the vertical façade area and are far too valuable as potentially usable open space. And conventional building façades simply don't provide enough energy yield.

A team of scientists from the Institute of Architecture at HTWK Leipzig is intent on changing this situation, - they want their solar façades to bring photovoltaic Systems (PV) into dense, urban spaces.

Professor Frank Hülsmeier's team from HTWK Leipzig has developed an energy producing façade with ALUCOBOND® tray panels in cooperation with 3A Composites. The geometry is three-dimensional and silicon half-cells adhere onto the upwardly inclined panel surfaces.

The first company building with this façade has been standing in Bad Rappenau for some time now. 400 PV modules are spread over two hundred ALUCOBOND® tray panels around the building. The total annual energy generation is 10,000 kWh. Enough, for instance, to supply two four-person households with electricity all year round.

A digital, parametric design process was needed to achieve this: software developed especially for the task calculates the optimal façade to produce the best light yield and, in so doing, the highest electricity yield for each and every location, compass direction and building. This obviously means that every façade has to be different; no location, no side of a building can be the same as the next

But, they do have one thing in common: they are all made of ALUCOBOND®, folded into lightweight but very strong tray panels. Special software calculates the optimal shape to produce the best light yield and minimise self-shading.

Using computer-controlled systems, the composite material can be precisely cut, individually folded into very different shapes bonded with PV modules and easily installed.

The HTWK Leipzig research group won, among other things, 3rd place in 2022 Reallabore Innovation Award special sustainability category because of the exemplary way in which new technologies are turned into concrete applications and create real added value for climate and environmental protection,.
