Open Access Government — the European Commission’s next EU long-term budget

Grapes ripening in the greenhouse

Open Access Government, edition 28, charts the priorities of the European Commissioner for Budget and Administration for the next EU long-term budget and the impact of COVID-19 on the Union.

The project is featured in the same edition, in the section on green energy technologies.

More coverage is collected under press; the technology itself is described on the project page.

How the glass is built

The panel is a laminate: an active layer carried between sheets of architectural glass, sealed at the edges and mounted in the same profiles a greenhouse or facade already uses. Nothing about the installation asks the builder to learn a new trade, which matters more for adoption than any laboratory figure.

Transparency is the design parameter that everything else follows from. A pane that passes most of the visible light leaves the crop unaffected but generates modestly; one that passes less produces more current and starts to shade. The specification is chosen per project, against the crop and the latitude it will grow at.
