Conservation is paramount

Ensure visual integrityNo anachronistic objects/buildingsNo higher than 22 meters

Changes should add value and be reversible

Energy savings measures respect monumental value or technical conditions

Anouk (39 years) lives in Wetering for the last 10 years.She works as a journalist and even if she is positive onchanging habits and adopting a more sustainable way oflife, she is too busy with her everyday life and cannotreally afford a big budget for this scope.

Nicole (65 years) is a designer, owner of an old traditional houseand passionate about sustainability. She lives a healthy life andloves organic food. She is willing to change the energyperformance of Weteringbuurt by contributing actively andfinancially.

Jan (48 years) is a successful lawyer, he owns a house inthe area for the last 5 years. His life is a continuous runand he is not really a fan of green energy andsustainability. He prefers spending his money to a yachtor a cottage.
