Impact you can check.
A source and a date sit under every number on this page. Where a figure is ours, it comes from our own products. Where it is the industry’s, we name who measured it.

01 · Carbon
Carbon, counted like money, while the design is drawn.
In Caldaia Studio, element by element, from official UK and EU data. Reported by the modules of EN 15978, with a range and a coverage beside the total; what is missing is named, never folded into a clean headline.
- 2028
- EU life-cycle carbon reporting becomes mandatory for large new buildings.
- 2045

Engineering time, back to engineering.
Heat loss, hydraulics, heat pumps and hot water, sized in one project from real products with their technical data and prices. The engineer’s judgement goes to the design, not to copying numbers from one tool into another.
