Evaluation– Element level

• Toxicity• Biological decay and accumulation

– Working environment– Long term effects– Relative

Cradle to Cradle tool

Research aim and field Preliminary research Cradle to Cradle tool Next steps

Conclusion– Building component

• Low score• No certified Cradle to Cradle solutions• Personal interest

– Façade• Low score• No suitable building products• Variety of aspect
