Carbon Footprint Analysis of HBV Modules in Timber Construction A Collaborative Study Between FHNW and ERNE AG Holzbau

Abstract

The construction industry is responsible for 37% of global CO₂ emissions, with cement and steel as major contributors. Cement alone accounts for 8% due to its energy-intensive processes. HBV modules, combining timber (a renewable carbon sink) and concrete, offer durability and sustainability. However, challenges like lifecycle emissions, transportation logistics, and low-emission material integration persist. ERNE AG Holzbau and FHNW partnered to analyze these issues and develop strategies to align HBV modules with climate goals and carbon-neutral practices.
