Air-conditioning water for green façades

NAMIB SYSTEMS™ · Engineered in the Netherlands

Green façades.Watered by your
air conditioning.

We collect the water your air conditioning produces, store it in a tank and use it to water the plants on your façade.

01 / 06Where it started

The idea behind NAMIB™

Use the water
that is already there.

In the Namib Desert, a beetle collects fog on its back. The droplets run down to its mouth. It survives not by finding more water, but by gathering what is already there.

That is the thinking behind NAMIB™.
Before we look for more water, we look at what a building already has.

FogWater to drink

02 / 06The source

Your air conditioning
also produces water.

When air is cooled, moisture turns into water. This is called condensate. In most buildings, it goes straight down the drain.

NAMIB™ collects that water for your green façade. How much planting it can support depends on your cooling system, the climate and the plants you choose.

Less water lost to the drain. More available for plants.

02 / 06District cooling

Connected to district cooling?
NAMIB™ can still work.

The chilled water from district cooling stays in its own closed circuit. The water NAMIB™ uses comes from the air: condensate that forms on the building’s cooling coils.

Cross-section of a building connected to district cooling: a closed blue chilled-water circuit runs from the district cooling plant to the air handling unit and back, while a separate green condensate route carries water from the cooling coil drain to the NAMIB™ unit and up to the irrigated green façade.

Cooling water stays in the system.
Cold water is supplied from the district cooling plant and returns through a closed circuit. NAMIB™ does not use this water.
Moisture in the air becomes water.
When warm, humid air passes over cold cooling coils, moisture condenses into water.
NAMIB™ collects it for your plants.
Condensate is collected, checked and, where needed, filtered or treated before it is used to irrigate the green façade.

Different water. Same building.

Explore the details

Blue — district cooling. Cold water is delivered through a network of pipes, cools the building and returns through a closed circuit. NAMIB™ does not use this water.

Green — condensate recovery. When cooling coils cool humid air, moisture turns into water. It leaves the units through condensate drains, separately from the chilled-water circuit.

These drains may eventually connect to the building’s general drainage system. NAMIB™ assesses the existing installation to determine whether recovery is feasible.

03 / 06How it works

From air conditioning
to green façade.

We connect water collection, storage and irrigation in one system. Here is the route the water takes.

01
Collect
Gather water from the air-conditioning drains.
02
Check
Assess whether the water is suitable for the plants.
03
Treat
Filter or treat it where the water quality requires it.
04
Store
Hold water in a tank until the plants need it.
05
Water
Send it to the plants when moisture sensors show they need it.

04 / 06Your building

Designed to fit
your building.

We look at where your air-conditioning water drains, where a tank can go and which parts of the façade can be planted. Maintenance access matters just as much as the planting.

Existing buildings

Find a water route that works with the systems and space already in place.

New developments

Include collection, storage and planting in the building design from the start.

05 / 06Smart control

Water the plants.
Keep the rest for later.

Sensors measure moisture around the roots. The system uses that reading, the water in the tank and the expected incoming water to decide when to irrigate.

AI suggests an action.
Set control rules determine whether the system carries it out.

Three examples of how the control works — not live building data.

Façade plantsSoil needs water

Water the plants

The plants need water and condensate is available. The system sends it to the façade.

What the system looks at

How much water is expected from the air conditioning, how much is stored and how moist the roots are. Those three inputs guide watering and storage.

Designed for the whole year

The water supply changes with humidity and cooling use. We consider wetter and drier months across a full year when sizing the tank and planning the planting.

06 / 06Your project

Could this work
on your building?

Start with four questions about your building, cooling and façade. Or talk to us directly about the water available and the planting you have in mind.

Experience, not just an idea

More than 27 projects in the Netherlands have shaped how we work with green façades. We bring that experience to a different question: how can a building’s own water support its planting?
