Priority model of sustainability
Individual areas are seen in their relationship and dependence on each other. No economy without society, no society without ecology.


Planning process
Anchor sustainability goals early in the planning process.

The dedication to develop sustainable buildings can be guided by an interest in marketing and reputation advantages, by increased demand from investors, tenants, and customers, or by striving to make a meaningful contribution to climate protection. In any case, everyone makes an essential contribution to achieving the goals of sustainable development of the 2030 Agenda and is part of the large group of actors.
We support wholeheartedly with our experience from almost 40 years of accumulated professional experience, recognized instruments for objective evaluation and knowledge from our research activities.

C5 makes it easier to build sustainably. We offer creative consulting for circular and certified construction.
