- Worth noticing
- The ventilation calculator lists room-by-room extraction rates from the 1982 order; the stair tool includes a Blondel check.
Field notes
The catalog is split into four groups, from measurements and masonry to finishes and energy or electrical work. Individual entries name outputs rather than merely the topic: the paint tool estimates liters and pots, while the stair tool includes a Blondel check. The homepage names source types such as DTU documents and decrees, and specifically lists the 1982 order for room-by-room ventilation extraction rates.
