Identification of the key sustainability area for the assessment of the office buildings

Abstract

The 2015 Paris Agreement marked the first global initiative requiring nearly 200 countries to act on climate change. The European Green Deal, launched in 2019, aims to further reduce greenhouse gas emissions by 2030. The construction sector contributes significantly to global emissions; consequently, it is scrutinised for its environmental performance at all building life cycle stages. The development of the real estate sector, where buildings are awarded environmental certificates, demonstrates the construction sector’s commitment to sustainability and reducing environmental impacts. No precise sustainability indicators and parameters exist for assessing buildings, their construction processes and other relevant parameters. The assessment of the footprint, for example, for the office building, is related to the technical parameters with required assessment documents like the Environmental impact, Resource use and Primary energy, Waste categories, Output flows, etc.
