CO₂ is the only goal. The balance covers the entire material cycle.

IAnticipation

Building is anticipation. What holds today — and what remains in thirty years.

A house has to carry two generations.

IICO₂

The greatest CO₂ lever is the house that is never demolished.

IIISubstance

Substance before gesture.

Structure and building physics are not deliveries to the design — they are the design.

We do not plan fast.
We plan right.

I · Anticipation

Planning decides conditions that will hold in thirty years. Structure, envelope and services are designed to survive a change of use: floor plans that can be divided, loads with reserve, components that remain individually replaceable.

II · CO₂

The operation of a house has become calculable; its production is rarely counted. We calculate across the entire material cycle: production, use, dismantling. An existing building that is reused ranks before any new build, because the embodied CO₂ has already been spent.

III · Substance

Object planning, structure and building physics sit in one HOAI process and in one hand. Spans, thermal bridges and connection details are decided together, not reconciled afterwards.

IV · Consequence

Attitude is verifiable. Every statement on this page must be found again in the structural analysis, the building physics and the construction documents. The HOAI phase 4 permit submission runs, for all projects requiring a building application, in cooperation with a partner architect registered in the AKNW architects list.
