Overview

Analysis reveals carbon reductions and material impacts in building energy renovation, suggesting strategies for economic benefits.

Key Points

  • Façade refurbishment reduces lifecycle emissions by 0.3% but increases material use by 21-25%.
  • Refurbishing heating systems shows greater carbon reduction potential compared to other methods.
  • Rebuilding could decrease emissions by 17% but would triple material use and construction costs.
  • Circularity strategies may offset 89% of material footprint and lower emissions by 23%, yet significant cost increases remain.
