Personas
Nicole (65 years) is a designer, owner of an old traditional house
and passionate about sustainability. She lives a healthy life and
loves organic food. She is willing to change the energy
performance of Weteringbuurt by contributing actively and
financially.
Anouk (39 years) lives in Wetering for the last 10 years.
She works as a journalist and even if she is positive on
changing habits and adopting a more sustainable way of
life, she is too busy with her everyday life and cannot
really afford a big budget for this scope.
Jan (48 years) is a successful lawyer, he owns a house in
the area for the last 5 years. His life is a continuous run
and he is not really a fan of green energy and
sustainability. He prefers spending his money to a yacht
or a cottage.
