Italian know-how · Egyptian buildings

Cooler buildings.
A lighter grid.

Ventilated façade systems designed for Egypt's hot, arid climate, backed by the construction experience of the EGY Holding group in Italy.

How it works The 2027 programme
50%

of Egypt's electric power goes to air conditioning in the peak summer months.

Alaa Olama, UNEP consultant and Head of the Egyptian District Cooling Code, quoted by UNEP, 2022.

The technology

A wall that uses the sun to cool itself.

Three layers and one air gap: an outer cladding, a ventilated cavity open at the base and at the top, and an insulated wall that the sun never touches.

Section of a ventilated façade: air enters at the base, rises through the cavity and leaves at the top

  1. Sun hits the cladding

    The outer panel absorbs the radiation instead of the structure.

  2. Cavity air warms

    Warmer air becomes lighter than the air around it.

  3. Hot air rises out

    It leaves through the top vents, carrying the heat away.

  4. Cool air drawn in

    Fresh air enters at the base. The flow never stops.

No fans. No power. Only physics.

In section

The wall, layer by layer.

Scroll and the cladding is fixed panel by panel. Once the cavity is closed, the warm air starts to rise and leaves at the top: no fans, no power.

The real obstacle

If it works so well, why isn't it everywhere?

Khamsin storms can fill the air cavity and stop the airflow. Sub-frames and cladding cost more than plaster on brick. Our design focus starts exactly there.

  • Filtered intake grilles at the base
  • Shielded outlets at the top
  • Cavity access for cleaning and inspection
  • Non-combustible cladding and cavity barriers

Design principles to be validated through testing and a monitored pilot.

The programme

Four steps from 2027.

A step-by-step path, starting from one measured building.

  1. Establish EGY Green

    An Egyptian company to lead the programme locally.

  2. Select suppliers

    International manufacturers chosen on climate performance.

  3. Build a pilot

    One façade, fully monitored, compared with a standard wall.

  4. Scale with data

    Measured results guide public and private projects.

Part of EGY Holding.

One group, two markets

EGY Holding also controls SMB S.r.l., an Italian construction company. EGY Green brings that way of building to Egypt, focused on one problem: buildings that overheat.

One building to prove it.

We are looking for a pilot site, access to the technical committees and joint monitoring of the results.
