Castel Madama, a town in Lazio near Rome, is rebuilding its primary school on Via della Libertà with a circular construction approach. Around 70% of the demolition waste from the old building will be reused, recycled, or recovered, and the new footprint will expand by only 5% compared with the previous structure. The project also adds solar panels, high-performance insulation, and a rainwater and groundwater collection system. The school is designed as a Nearly Zero Energy Building and is targeting energy use at least 20% below NZEB standards. It will have flexible classrooms, a green classroom for outdoor learning, and public areas that stay open to the community outside school hours. Construction is underway and the school is expected to open for the 2026/27 academic year.

Good to see demolition waste getting a second life. 70% reuse is a solid number, but I would like to know how they sort the rubble on site and whether the recycled aggregate is actually certified for structural use. The rainwater collection part is easier to pull off, but it only matters if they publish usage data.

This is the kind of project that makes circular construction feel concrete. Castel Madama is not a big showcase city, so the costs and the permitting process here could tell us more about scaling than another flashy pilot. The NZEB target with 20% extra savings is fine, but the real test is measured performance after a year of classes.

Solar panels on a school roof are straightforward. The harder part is the energy model. NZEB definitions vary by country and the 20% below standard claim depends on which baseline they use. I would want to see the actual heating and cooling loads, plus whether the grid connection allows export or if they are just offsetting daytime use.

The 5% footprint increase is a good constraint. It forces the design team to work with the existing site instead of spreading out. I would be curious about the wall assembly and insulation thickness, because that is what will actually cut the heating bill, not the label. Also, schools are empty in summer, so the solar array should be sized for export or storage.

Circular construction tends to live or die by procurement rules. If the tender only scores on price, the contractor has no incentive to recover 70% of the rubble. This project looks like it baked circularity into the brief from the start, which is the part other towns should copy. It would help if they published the waste audit before and after.
