HolzBauten

HolzBauten is a term used to describe buildings whose primary structural material is wood. It encompasses traditional timber-frame and log construction as well as modern mass timber systems such as cross-laminated timber (CLT), glulam, and laminated veneer lumber. Wood elements may form load-bearing frames, floors, walls, and roofs, and are often combined with other materials for performance reasons.

Historically, wood has been a common building material across many regions. Traditional timber framing dates to medieval Europe and other forested areas. In recent decades engineered wood products and prefabrication have expanded wood’s role into mid-rise and, in some jurisdictions, tall buildings, driven by sustainability goals and faster construction.

Advantages of HolzBauten include light weight, rapid on-site assembly, good thermal insulation, and lower embodied energy compared with steel or concrete. Wood also stores carbon during its service life. Challenges include sensitivity to moisture, potential decay or pests, and fire safety considerations. Modern design mitigates these issues through protective detailing, treatments, moisture barriers, and compartmentalization of fire resistance.

Environmental aspects emphasize sustainable forest management and certification schemes. Life-cycle assessments often show favorable carbon performance for wooden buildings when forests are responsibly managed. End-of-life options include reuse, recycling, or energy recovery, depending on wood species and treatment.

Regulatory context encompasses building codes and standards that govern fire resistance, structural design, moisture control, and indoor air quality. In many regions, regulations are evolving to accommodate mass timber and prefabricated systems, promoting standardized connections and evidence-based fire testing.
