This study evaluates building materials in terms of CO2 emissions, primary energy demand, and thermal behavior of an office unit with three different ceiling construction types. Simulations of the construction types are performed to assess the impact of their thermal mass on energy demand. The variants are analyzed regarding the life cycle stages of production, construction, operation, end of life, and benefits outside the system boundary. The results show that over a life span of 50 and 100 years, the unit with a solid timber ceiling has the lowest CO2 emissions and non-renewable primary energy demand compared to the others.     «
