Integrated evaluation of CO2eq emission and thermal dynamic simulation for different facade solutions for a typical office building

摘要

This paper presents the results of comparative analysis of energy and environmental life cycle assessment of a building envelope with different WWR. The analysis is simplified to: product stage and use stage as the main sources of GHG emissions. Embodied and operational CO2 equivalent were evaluated for two typical office buildings located in Poland with different wall to floor ratio. Carbon footprint of the use stage, associated with the energy consumption, was calculated according to polish energy fuel mix. The maximum emission of CO2eq occurred for the scenario with glass curtain wall and it decreased along with reduced window area.
