Generating energy by design

Structural Solar Façade transforms the building envelope into an energy-generating system — a new façade typology that replaces conventional cladding while adding the capacity to generate energy, for retrofit and new building alike.

A lightweight structural layer integrates translucent photovoltaic modules into a permeable façade system, producing renewable energy while maintaining daylight and spatial quality.

Designed by architects. Engineered for construction.

High performance with a clear and refined architectural expression.

Large building surfaces hold untapped energy potential. Structural Solar Façade activates it at scale.

Modular by design, the system extends seamlessly across façades while maintaining a clear structural order.

Applicable across a wide range of mid-rise building types:

industrial
logistics
commercial
office
public buildings
residential (targeted)

01 Works with existing buildings

Installed in front of the façade with minimal intervention, scalable across large surfaces

02 Turns façade cost  into value

Combines building envelope and energy generation into a single system

03 Enhances architectural
quality

A precise and efficient structural logic

Each façade field combines photovoltaic modules with a lightweight, highly engineered steel support structure anchored directly to the primary structure.

Organised around a vertical mast with horizontal arms, the system forms a slender, permeable layer that establishes a clear structural rhythm while minimising the number of connection points.

All colours

transparency

0% 90%

Designed for architectural thin-film photovoltaic modules, the system offers a wide range of transparency levels (0%- 90%) and colour options.

The façade filters daylight while generating electricity, with modules positioned in front of opaque surfaces or in combination with glazing, acting as a daylight-modulating screen—reducing solar radiation and heat gain.

As daylight passes through the modules, the supporting steel structure remains visible—contributing to both improved interior comfort and a carefully composed architectural expression.

A clear architectural order and efficient installation

The system is conceived as a secondary façade layer, installed in front of the primary building envelope, allowing integration into both refurbishment projects and new developments with minimal intervention and reduced disruption.

Structural connections to façade elements or slab edges enable adaptation to different building configurations.

The system can be supplied as a product or integrated into projects with full support.

SEE HOW WE WORK

Applicable across industrial, logistics, residential, office, commercial and public buildings, as well as façade refurbishment projects.

Particularly suited to upgrading existing mid-rise buildings, enabling photovoltaic generation without altering the primary envelope.
