CO2 payback of aluminium renovation systems

To illustrate how the energy performance of existing buildings can be upgraded, the European Aluminium compiled renovation case studies and performed simplified life-cycle-assessments focusing on greenhouse gas emissions. Examined buildings are located in Zeist (NL), Denkendorf (D) and Thessaloniki (GR). The three analyses concluded CO2 payback periods in the range of one to five years. An independent expert has been involved in order to secure the scientific validity and technical quality of the results.
