About us

We are the pioneers of the sustainable energy revolution

The 21 Degrees journey began with a pivotal moment in 2007. Driven by a healthy sense of scepticism, our co-founder, Chris, attended a Passivhaus conference with the intention of debunking this emerging, radical concept from Austria and Germany. But what he discovered there changed everything. Instead of finding lofty ideals or impracticality, he faced the true problem: the traditional, wasteful methods of energy consumption that had dominated the building industry for decades. Chris saw how inefficient practices were draining both the environment and people’s wellbeing – and how Passivhaus principles held the key to a better future. The enemy was no longer the new ideas, but the stubborn resistance to progress.

Rather than a sceptic, Chris returned as a believer – inspired by the potential of harnessing renewable energy, reducing waste, and transforming how buildings could empower people to sustainably meet their energy, health, and comfort needs. Today, 21 Degrees stands as a leader in this revolution, driven by our unshakable commitment to challenge outdated systems and champion sustainable living. Every home, business, and industrial facility we touch is not just built to meet expectations – it’s designed to exceed them, setting a new standard for energy performance, environmental stewardship, and human wellbeing. Our world is changing, and the opportunity is now. Change the way you think about energy.
