Why BR18's 2026 amendments are a PM problem, not a designer problem
The new energy and accessibility chapters do not change much for architects. They change a great deal for whoever holds the documentation chain through kommunal sign-off.
BR18's 2026 amendments tighten the energy-frame calculation and the accessibility clearances. Designers will adjust. The shift is downstream: the documentation chain that satisfies the kommune at hand-over now sits squarely in the project manager's domain — and it needs to be assembled from week one, not week forty.
Energy-frame recalculations are now required at every material design change. On a fit-out programme that means a recalc at brief sign-off, at the end of design development, at any post-tender variation, and at handover. We have started baking that schedule into the master programme from kick-off; doing it retroactively is where projects lose two weeks at PC.
Wider accessibility clearances change the partitioning grid on almost every project we have walked this quarter. Catch it before tender, not after. The cost delta is a rounding error if it lands in the drawings; it is a full re-tender if it lands in the snag list.
Kommunal response times have lengthened across most of Sjælland through the second half of 2025. We are now writing a four-week buffer into closeout programmes by default — and starting the documentation pack ten weeks before PC, not six.
