Timberdate – Dein Date mit Holz

Die Veranstaltungsplattform rund ums Holz

5th Forum Wood Building Baltic (WBB)

5th Forum Wood Building Baltic (WBB)

Forum Wood Building Baltic is the main conference for architecture and engineering topics of wooden buildings: design for manufacturing and assembly, building physics, energy performance, fire safety etc. in the countries around Baltic Sea. The conference  is a part of the international organization Forum Holzbau. The overarching theme of Forum Wood Building Baltic 2024 is integrated design where different disciplines come together with their own possibilities and limitations to cooperate and push the boundaries of innovation in timber construction.

Scope of the conference:

— Regenerative and circular architecture
— (Prefabricated) timber-based renovation solutions
— Process innovation in design and construction of wooden buildings
— Timber structures (Eurocode 5)
— Fire safety in timber buildings
— Building physics of timber structures
— Zero emission wooden buildings (LCC, LCA)
