Climate-ABC: X-Factor

The X-factor is the unit of measurement by which resource consumption must be reduced to achieve better energy efficiency.

Increasing resource productivity by the X factor describes sustainable development. In house building, for example, the X factor stands for particularly climate- and resource-friendly construction. The entire life cycle of the house is taken into account.
