About 20 Degrees
20 Degrees is a collaborative healthy housing programme, delivered by Sustainability Options. We provide free home assessments for anyone interested, living in the Bay of Plenty. Whether a whānau rents, owns a home, or anything in between, we will take a journey with whānau to help whare reach a healthy 20°C on a cold winter’s night.

The 20 Degrees Vision
Founded by Sustainability Options, the 20 Degrees vision arose when the team found themselves visiting far too many homes facing cold, damp conditions that were threatening their health and wellbeing.
Sustainability Options recognised the magnitude of this problem across the Bay of Plenty and knew that one organisation couldn't address it alone. This is why 20 Degrees partners with community organisations that are already working alongside whānau/families in need, to help maximise our impact.
Who is Sustainability Options?

Sustainability Options believes in the simple act of giving forward, acting with kindness towards those in our communities and kaitiakitanga towards the environment.


Why 20 Degrees?
