To Decarbonize or Not to Decarbonize: A Case Study of a High-Rise Office Building in Frankfurt am Main

In this case study, we investigate the financial and technical implications of decarbonizing a high-rise office building in Frankfurt am Main, Germany. This paper provides insights into energetic assessment modeling, energy-saving projections, and the investors’ economic decision-making process of implementing sustainability action roadmaps. Furthermore, the impact of reduction in energy and greenhouse gas emissions (GHG) on financial performance indicators is presented. This case can be used as an introduction for property owners to understand the methodology for energy performance assessment and to make informed investment decisions regarding the reduction of greenhouse gas emissions and energy consumption.
