Make every building use less and breathe better.
Ewan uses affordable sensors and artificial intelligence to assess the real condition of existing buildings — then delivers smart recommendations that cut energy and water use while improving indoor air quality.
Three levers, one healthier building
Most existing buildings quietly waste energy and water while air quality goes unmeasured. Ewan makes all three visible — and then improvable.
Energy
Pinpoint where power is lost — HVAC, lighting, standby loads — and act on AI-ranked fixes that lower bills without disrupting the building.
Water
Detect leaks, over-use and inefficient fixtures early, and cut consumption with targeted, data-backed recommendations.
Indoor air quality
Continuously track CO₂, particulates, temperature and humidity so the spaces people live and work in are genuinely healthier.
From sensor to savings in four steps
Low-cost hardware, cloud AI, and clear recommendations — designed to retrofit the buildings we already have, affordably.
Deploy sensors
Affordable, easy-to-install sensors start capturing energy, water and air-quality data across the building.
Analyze with AI
Our models learn the building’s patterns and benchmark performance to reveal exactly where resources are wasted.
Get smart recommendations
Receive prioritized, cost-aware actions — ranked by savings, payback time and comfort impact.
Track results
Watch savings and air quality improve in real time on a simple live dashboard.
Built for real buildings, real budgets

Lower costs today. A lighter footprint for good.
Buildings are among the largest consumers of energy and water. By making existing ones smarter — instead of tearing down and rebuilding — Ewan delivers savings that pay back quickly and sustainability that lasts.
“We don’t need to rebuild our cities to make them sustainable — we need to understand the buildings we already have, and make them work smarter.”
Dr. Abdelhaleem Khader
Dr. Khader founded Ewan to bring affordable, data-driven sustainability to Palestine’s existing building stock. By combining low-cost sensors with artificial intelligence, the company turns everyday buildings into healthier, more efficient spaces — cutting energy and water consumption while protecting the environment and the people inside.
