- On 16 September, we will bring our technical expertise to The 87 DAY in Brussels, contributing to two key task forces: Alexandre Chaudron leading "Who Owns Urban Data, and Who Can Use It?" Nicolas Lambilliotte participating in "Urban Digital Twins for Decision-Making" Today, real estate data is trapped in silos. Tomorrow, those who own and master this data will lead the industry.

- What if Claude Code could be connected to your building data? For the past few months, Data4Green has made it possible. We built an MCP connector that links AI directly to your portfolio. No exports. No intermediaries. No waiting. Ask a question. Build a dashboard. Check compliance. Get the answer in seconds. One condition: your data needs to be clean, centralised, and structured. That's exactly what we do first.
- WAT.BXL(beta) isn't just our office space. It's a live test on how buildings can actually perform. Over the past months, Data4Green has been tracking air quality, temperature and consumption across the building to improve all three. 🌬️ Air quality: improved by 17% since end of May 2026. Collaboration with AIRSCAN.org ⚡ Energy: WAT runs on a local energy community with RaYSun and energilia. 60% of May consumption came from shared solar surplus with neighbours. (9 tons/yr of CO2 avoided & cheaper electricity) 🔥 Heating: target
- Data4Green will be at the Young Leaders Summit, hosted by EightySeven (ex-PropTech Lab). Our Managing Partner Nicolas Lambilliotte will be there Thursday morning for a session on AI, innovation and leadership in construction and real estate. Nicolas will present our latest innovation: connecting real estate data to any #AI platform. Building data has always been scattered and hard to access. That's changing now. 📆 Thursday, July 9 | 9:00 AM – 1:30 PM 📍 87 Hub, Bd de la Woluwe 2, Brussels
- 100 assets. 10 countries. 120,000 m². This map is just getting started. 🗺️ When we launched Data4Green, the ambition was clear: help real estate players master their building data to make sustainability profitable, obvious, and effortless. Today, this map shows where we are. One day, it should be entirely covered. Because every building on this map is a building that knows its energy consumption, tracks its emissions, and acts on real data instead of guesses. Proud of the journey. Excited for what's next.
- Last week, the Data4Green team spent a day racing sailboats on the North Sea at Sailing for Climate 2026. Sun, wind, a bit of friendly competition. ☀️⛵ The perfect mix for a great team-building event. You can't sail without reading the wind. You can't save energy without reading your data. Big thanks to the teams who shared the water with us (XLG, SEL Studio, IBA, TRACTEBEL and many more). A special shoutout to Flexisailing for organising such a unique day.
- We analysed 20+ buildings in Brussels. Every single one had at least €10,000/year in easy energy savings. Without any mandatory CAPEX. Just waiting… Most owners have no idea, because nobody ever ran the numbers for their specific building. So we built a #financial scan that does it. From your address alone, you get: → Your estimated energy savings → Your rooftop solar production or optimisation potential → The funding Brussels gives you to act on it. (subsidies, green certificates, energy communities...) The scan is free until June
- Romain is officially joining Data4Green on a permanent contract. Some of you might remember when we welcomed him as an intern a few months ago. Turns out, once you have Romain on the team, you don't let him go. He continues as Data Analyst, turning complex datasets into decisions that drive real impact on buildings. Focused on maximising the #financial and #sustainable ROI of our clients, straight from field data. Welcome to the team, Romain. For good this time. 🙌
