Overall Description

This funding topic supports innovative strategies and model projects contributing to an energy- and resource-efficient, climate-neutral and healthy building stock by 2050. It covers the optimisation of existing buildings, environmentally compatible urban densification and sustainable approaches to new construction.

Projects should take an integrated, whole-life-cycle approach and combine technological development with high-quality design, planning, evaluation, documentation, education and dissemination. Particular attention is given to timber construction, circular construction, healthy indoor environments and digital planning tools.

Funding Amount
