Estimation of base-values for Grey Energy, Primary Energy, Global Warming Potential (GWP 100A) and Umweltbelastungspunkte (UBP 2006) for Swiss constructions from before 1920 until today

Abstract

This paper presents a framework to estimate base-values for embodied energy and CO2 emissions of the Swiss building stock. These values are estimated for existing, renovated and future constructions. Using the approach of Fonseca et al. (2014), the impacts of standing and future buildings at the urban scale can be calculated from these values. The framework allows to quickly estimate the environmental impact of a set of buildings from its year of construction or renovation, saving the effort of a thorough examination of buildings properties. The work was done as part of the so called INDUCITY Project by ETH Zürich, Siemens A.G. and WERZ institute (2014), which compared the impacts of embodied energy in buildings for the sustainable transformation of an urban area in Switzerland.
