🌞 Solar Impulse Foundation Endorses WaterRoofs – A Recognized Efficient Solution

A global validation of evaporative roofing as a climate, circular, and urban innovation

The Solar Impulse Foundation, founded by explorer Bertrand Piccard, is one of the world’s leading platforms for vetting and endorsing sustainable technologies that are both profitable and climate-positive.

After a rigorous evaluation process, WaterRoofs has been officially recognized as a Solar Impulse Efficient Solution — placing it among a global portfolio of high-impact innovations capable of accelerating the ecological transition.

This endorsement validates what scientists, architects, and climate experts increasingly understand:

👉 Cities cannot stabilize their climate without restoring evaporation. And rooftops offer one of the most effective pathways.

🌍 Why This Endorsement Matters

The Solar Impulse label is internationally respected because it combines:

• scientific validation

• environmental performance

• economic feasibility

• scalability of deployment

For WaterRoofs, it highlights that evaporative roofing is not just an architectural idea — it is an actionable climate solution ready for cities worldwide.

This recognition acknowledges three pillars of WaterRoofs:

1️⃣ Climate value

Reintroducing evaporation reduces heat islands, restores humidity, and stabilizes microclimates.

2️⃣ Circularity

Tiles are made from 100% recycled PET, reducing waste and closing the material loop.

3️⃣ Innovation

Micro-channel engineered tiles mimic forest evapotranspiration — a world-first in roof design.

💧 WaterRoofs: Rebuilding the Evaporation Cities Lost

Modern cities are covered by 3 million km² of dry roofs — an area equivalent to India — that push rainwater away instantly. This breaks the natural water cycle and worsens heat, drought, and atmospheric instability.

WaterRoofs reverses this pattern through:

• micro-grooves that retain rainfall

• gradual evaporation that cools and humidifies the air

• PET tiles that remain durable in all climates

• a modular system suitable for new builds or retrofits

It is a simple but powerful principle:

M² of WaterRoofs = M² of evaporative canopy M² = M² (forest)

The roof becomes a climate-regulating surface, much like a forest canopy converts water into cooling vapor.

🎯 Alignment With the UN Sustainable Development Goals

The Solar Impulse Foundation evaluates solutions partly on their contribution to the SDGs. WaterRoofs advances several of them simultaneously:

SDG 6 — Clean Water & Sanitation

✔ Restores the water cycle 

✔ Reduces runoff and drainage overload 

✔ Returns moisture to the atmosphere

SDG 7 — Affordable & Clean Energy

✔ Passive cooling reduces the need for air conditioning 

✔ Evaporation provides natural temperature regulation

SDG 9 — Industry, Innovation & Infrastructure

✔ Patented evaporative roof system 

✔ Engineered micro-channel technology

✔ Circular material integration

SDG 11 — Sustainable Cities & Communities

✔ Slows heatwaves 

✔ Reduces flood risks 

✔ Improves urban climate resilience

SDG 12 — Responsible Consumption & Production

✔ 100% recycled PET tiles 

✔ Recyclable up to 40 times 

✔ Supports a circular construction economy

This is what makes WaterRoofs exactly the type of innovation Solar Impulse seeks to elevate: practical, scalable, and regenerative.

🏙️ Turning Rooftops Into Climate Engines

Roofs were once static, passive, and environmentally silent. Today, they can become active climate tools.

With WaterRoofs:

• rainfall becomes cooling power

• evaporation becomes temperature regulation

• PET waste becomes architecture

• rooftops become urban forests in function

This recognition confirms that evaporative roofing is not just a promising concept — it is a validated solution ready for global deployment.

🥇 A Milestone for Evaporative Architecture

Solar Impulse’s endorsement places WaterRoofs among globally recognized climate innovations. It confirms what our research, pilot projects, and atmospheric modeling have shown:

👉 Restoring evaporation in cities is essential for climate resilience. 

👉 Circular materials can lead to high-performance architecture. 

👉 Urban rooftops are one of the greatest untapped climate assets.

The journey is just beginning — but the momentum is strong.
