Circular Economy
Basis materials tracing based on: • Concentra<on • Purity • Structure
Buildings cover 1/3rd of materials!
When does economy work?
Scarcity + Prosperity According to em.prof.dr.Heertje Value is an opinion! Whoever calls upon this opinion?
“The only constant is change” Heraclitus, Greek philosopher (app. 500 BC)

Investors interests (B2B)
Trends: -‐ Maximal return on investment -‐ Cash vs value -‐ Minimal risk on unlefable
merchantability
Transparency on what? Secrecy on how much?
From linear to circular
Steps to take – value to make
Material track value break!

Circular building ownership?
Tastes of law: (NL) Merge? (B) Return? (D) Share? (F) Revive? (EU) Split?
download at: briqs.org 2015: ECB in charge for major EU banks?
What do we need?
• Financial models in real estate including material value in <me
• Ownership revised staying simple and transparent
• Contract models for building industry to stay user involved
• Real <me measuring of performance, costs and value opportuni<es
Five economics needing a twist
• End-‐User • Investor • Local Government • Building Industry B2B • Building Industry B2C
No pilot, just projects to do: Circular Building Hoofddorp (Schiphol)
